It is avowedly a compilation, and hence, with a few exceptions, no authorities are given for the statements which it contains. Perhaps the following reasons may serve as an apology for attempting to add another work on Obstetrics, to the numerous excellent treatises which have been published within a few years past. Having been for several years engaged in teaching Midwifery, I have experienced the want of some handbook for students attending lectures on this department, a skeleton collection cf facts, which, by being interleaved, might answer as a syllabus for the teachings of any school. I therefore took as a basis my notes of the lectures of Pro- fessor Gilman, and gradually, for a number of years, added such facts and opinions as reading and experience developed. Without seeking to turn aside the student from the study of elaborate treatises, from which alone he can learn reasons for practice, this little work is designed to convey as briefly as possible, facts, as far as ascertained; and, where definite conclusions have not yet been reached, recent opinions, so as to present, as near as may be, a miniature of modern Obstetrics. To the student, it is hoped it may proved an useful and acceptable companion, in the lecture room and in the examining class; while the young practitioner, in his moments of emergency, may per- haps find an issue from his trouble, suggested by a hasty glance at its pages.

Sha])e seen best by removing the ilia by horizontal section; is then seen to be a curved canal; larger in middle than at extre- mities. Ls divided into two straits and a cavity. Abdominal or Superior Strait or Brim.—Formed, behind by promontory and anterior border of alae of sacrum; laterally, by edge of iliac fossa; anteriorly, by superior edge of pubes and horizontal ramus. Shapel said to be heart-shaded ; better a truncated triangle, with base behind, apex in front. Circum- ference, fourteen inches. Has four diameters:—1st. Antero- posterior, or sacro-pubic, or conjugate, or straight, four inches. 2d. Transverse, or lateral, or bis-iliac, five and a quarter inches. 3d and 4th. Oblique, or diagonal, five inches. Sacro-cotyloid, one on each side; from promontory to acetabulum, three inches ten lines. Inferior or Perineal Strait or Outlet.—Boundaries, the inferior part of symphysis pubis and the descending ramus ; the ascending ramus and tuber ischii, by inferior mar- gin of great sciatic ligament, and by the border and point of the coccyx. Shape, oval, interrupted by three osseous projec- 16 MANUAL OF OBSTETRICS. tions. Circumference, thirteen inches six lines. Has four dia- meters: 1st. Antero-posterior, or coccyx-pubic, four inches, increased to five by recession of coccyx. 2d. Transverse, or bis-ischiatic, four inches, immovable. 3d and 4th. Oblique, four and three quarter inches, increased by elasticity of sciatic ligaments. Cavity, the space between the superior and inferior straits. Dimensions.—Height in front, one and a half inch ; on sides, „aree and three quarter inches. The chord of arc of sacrum, four and a quarter inches ; following face of sacrum, five and a quarter inches. Has four diameters, taken at centre: 1st. Antero-posterior, four and three quarters to five and one eighth inches. 2d. Transverse, four and three quarter inches. 2d B,ndx$d.\-X)blique, four and three quarter inches. By dividing the cavity equally, by sections at right angles, two sets of inclined planes are seen, which are supposed greatly to influ- ence the changes in direction necessary for the foetal head to perform in its descent; some, however, say that the motion of rotation is executed when the head is below the influence of these planes. The anterior planes are directed from without inwards; from above, downwards; and from behind, forwards. The posterior are from without inwards; from above, down- wards ; and from before, backwards. Arch of Pubes.—The angle formed by the descending rami of pubes, and ascending rami of ischium; 90° to 100°. At base, is three to three and three-quarter inches broad ; at apex, two inches. Base of Pelvis presents, posteriorly, the notch filled by the promontory of sacrum; laterally, the iliac crests; anteriorly, the spinous processes; notches for muscles and nerves, the spine, horizontal rami, and symphyses of pubes. Apex presents, posteriorly, the coccyx ; laterally, the sacro- sciatic ligaments and tuber ischii; anteriorly, the rami of the ischium and pubes. Direction of Pelvis is not horizontal, but the plane of superior strait inclines at an angle of 55° to 60° from above MANUAL OF OBSTETRICS. IT downwards, and from behind forwards; its inclination alters with position and in gestation. Advantages of this position, to prevent protrusion of pelvic contents, and to afford support, both in pregnant and unimpregnated condition. Axis of Superior Strait is a line drawn perpendicular to the centre of the plane of the strait; terminates anteriorly, near umbilicus; posteriorly, at union of upper two thirds of coccyx with its inferior third. Axis of Inferior Strait, a line from above downwards, and from behind forwards, running from first piece of sacrum, # and falling at a right angle upon the middle of the bis-ischiatic space. The axes of the two straits cross in the cavity, forming an obtuse angle. Axis of Cavity, a curved line parallel to curve of sacrum; is the curve the foetal head must follow in its expulsion ; " cufve of Cams." By comparing the diameters of brim and outlet, it will be seen that a complete change is effected in the relative lengths, which necessarily influences the passage of the head. At the brim, the antero-posterior diameter is four inches ; at the out- let it may become five. The transverse, at the brim, is five and a quarter; at the outlet, four. These changes are effected by degrees, so that the advancing head is gradually turned from having its long diameter in the oblique diameter of the brim to the antero-posterior or long diameter of the outlet. other dimensions. Between two anterior superior spinous processes, 9£ inches. Between highest part of crests of ilium, 10i inches. From crista ilii to tuber ischii of same side, 7 inches.

Depth of symphysis, at least two inches. A line drawn from sacro-iliac symphysis directly forwards, cuts off but little of superior strait. Recent Pelvis.—The soft parts entering into the composi- tion of the pelvis serve to smoothe angularities, to protect the AI03 of ilium, larger, wider, shorter, lighter. Capacity greater. Sacrum, shorter, more con- cave, wider; not so thick. Coccyx, more movable. Brim, long diameter trans- verse. Cavity, more shallow. Tubera ischii further apart. Arch of pubes, angle 90°— 100°. Foram. thyroid., triangular. Depth of symphysis, 18 lines. Cuts off much more. MANUAL OF OBSTETRICS. 19 nerves and vessels during labor, to deaden shocks in moving, and at the same time materially change the shape. The superior strait is influenced by the iliacus internus late- rally, by the psoae posteriorly ; while anteriorly the abdominal muscles are inserted, which assist in expulsive efforts. Superior Strait.—The psoae, rising from the sides of the lumbar vertebrae, pass down, filling the fossae alongside of the promontory, and are inserted conjointly with the iliacus inter- nus into the trochanter minor. By them the shape is changed from oval to triangular, with the base in front; the transverse diameter is shortened half an inch ; they can be compressed in labor, but in very muscular women their action may retard the process; they should be relaxed by flexing the thighs on the trunk. (In the recent state, the pelvis is widest between the ilio pectineal eminences; the transverse diameter being four inches and some lines, while the bis-iliac is one and a half to four inches; beneath the promontory, the transverse is five inches.— Velpeau.) Cavity is influenced posteriorly by the sacral plexus, the hypogastric vessels, pyramidalis muscle, and rectum; ante- riorly, by bladder, obturator internus, obturator vessels, and nerves; laterally, by adipose tissue; vertically, by the perineum; composed of two layers, 1st, superior, concave above, formed by levator ani and ischio-coccygeus; 2d, inferior, concave below, formed by sphincter ani, transversus-perinei, ischio- cavernosus, and constrictor vaginae. The perineum closes the inferior strait; is pierced by urethra, vagina, and rectum. Inferior Strait, influenced by sacro-sciatic ligaments, coccy- geus, adipose tissue, fascia. Uses of the Pelvis.—A foundation for the trunk; a fixed point for muscles ; to protect the pelvic contents in the unim- pregnated; to support the gravid uterus; to direct the foetus in parturition. Two arches are formed: a posterior or superior by the ilia and sacrum; an anterior or inferior by ilia, ossa pubis, and ischia. The ilio-femoral articulation serves as an abutment to both. 20 manual of obstetrics. Deformities of the Pelvis, may influence, first, the whole pelvis; second, some parts; third, may modify the incli- nation, and change the direction of the apertures and axes. DEFORMITIES OF THE WHOLE.—First, by excess; second by diminution. By excess, primA facie not objectionable, but is so ; in the unimpregnated state the uterus is liable to ante, or retro- version, or prolapse. In pregnancy, the uterus falls too low, and compresses rectum, bladder, vessels, and nerves, producing rectal and vesical tenesmus, fecal accumulation, piles, varices, oedema, and cramps. Late in pregnancy, these symptoms recur with more or less intensity; in labor, the expulsive efforts may extrude the uterus, may lacerate the cervix or the peri- neum, may cause haemorrhage by premature separation of the placenta, may rupture cord, may produce inversion of uterus. By diminution, may be uniformly diminished. DEFORMITY OF PARTS.—First, by excess; second, by di- minution. May affect either greater or lesser pelvis. The diame- ters most affected are anterior posterior of the brim, and trans- verse of outlet. Greater Pelvis, affected, first, by too great curvature of the vertebral column, which causes obliquity, and delays labor; second, the alae may be too wide; or third, too narrow. . Lesser or True Pelvis, affected in Apertures, Cavity, or all parts. Of Superior Strait.—Cordiform shape, or reniform, figure OO, triangular, trapezium; more frequently than any other part. Antero-posterior diameter most affected, and all di- mensions occur, from four inches to three lines. Caused, first, by projection of the base of the sacrum; second, by turning back of the horizontal rami of the pubes ; third, by both com- bined- Transverse diameter affected, first, by approximation of the ilia; second, by projection of ossa pubis, both of which changes also increase the antero-posterior diameter. Ob- lique diameter affected, first, by projection inwards of ilia • second, by projection inwards of one side of pubes, while manual of obstetrics. 21 the other bulges outward; produces the "obliquely ovate" pelvis; not uncommon. A woman thus affected may be readily delivered if the long diameter of the head presents in the great oblique diameter, and the bi-parietal in the contracted diameter; while the reverse presentation may require instru- mental aid; in these cases, version may possibly remedy the dif- ficulty. Inferior Strait.—Affected, antero-posterior, by projection forwards of coccyx, by turning up the base of the sacrum; though a mobile coccyx relieves this. Transverse, by approxi- mation of the tubera ischii; is the worst form, because of the immobility. Oblique, by vitiated direction of ischio-pubic rami. Arch of Pubes may be contracted like male pelvis. Spine of ischium may curve inwards. The deformities of the two straits may be compensating; i. e. one enlarged and the other contracted, and vice versA ; so that labor delayed in one stage may in another stage be quite rapid. Sometimes, but rarely, both straits may be contracted, as when the sacrum has too great a curvature, the antero-posterior diameter of the cavity is increased, while the same diameter of each strait is decreased. Cavity, affected, first, by turning back of ossa pubis; second, by projection inwards of inter-pubic fibro-cartilage; third, by excessive length of symphysis pubis; fourth, sacrum too much curved, increases antero-posterior diameter; head rests too long, or else, occiput not advancing, produces extension, which results in face presentation; fifth, sacrum too flat, head cannot rotate, may cause death of child, or great compression of soft parts of mother; sixth, by morbid growths, exostoses, fibro- cartilage. Defective Inclination of Pelvis.—Usually results' from deformities. The inclination may be increased or diminished. Causes of Deformity.—First, and most common, is Ra- chitis, or Rickets, a disease of early life, in which the earthy part of the bone is imperfectly elaborated ; second, from Mala- costeon (Osteo-malacia, Mollities Ossium); occurs later in life ; manual of obstetrics. • the earthy matter is deficient; third, from exostoses, mal-united fractures, morbus coxarius, unreduced dislocation, anchylosis of sacro-ooccygeal articulation from inflammation. Known by.— Inspection or Pelvimetry. A true pelvis should have well rounded hips, and of equal height; the anterior spinous pro- cess, eight or nine inches apart; from iliac crest to tuber ischii, seven inches ; tuber ischii, four inches apart, and on same line. If the hips are projecting and elevated, or the sacral region flat or convex, or arch of pubes narrow, or tubera ischii narrow, or unequal, suspicion will be excited. Pelvimetry, by Baude- locque's calliper, Coutonly's pelvimeter, or simply by the hand. By Baudelocque's, the limbs are placed on pubes and on sacrum ; should measure seven inches; subtract two and a half for sacrum, and one and a half for pubic bones. For oblique, place one end on trochanter major, the other over sacro-iliac symphysis ; should measure nine inches; subtract two and three quarter inches; plus, twenty lines. Inaccurate. By the hand.—Reach for promontory of sacrum ; if it cannot be reached, the antero-posterior diameter is probably suffi- cient ; exceptions to this rule occur. Examine height of sym- physis, width of arch, spines of ischium, shape of the straits. Of course, manual examination is permissible only in the mar- ried, and in these alone is it likely to be required. Fortunate- ly, American practitioners see comparatively few deformed pelves ; such abnormalities are almost invariably found among our foreign population. vessels concerned in obstetrical practice.

Obturator, a branch of int. iliac; emerges from upper border of foramen. manual of obstetrics. 23 Uterine, a branch of int. iliac; is very tortuous ; ascends in the folds of broad ligament. Ovarian, from aorta. Int. pudic, branch of int. iliac; emerges through great sciatic notch ; re-enters smaller foramen, crosses to the ramus ischii; supplies the vagina. Ischiatic, branch of int. iliac; emerges from greater foramen. Veins, usually accompany the arteries. The external iliac vein at the brim lies behind the artery. Pressure produces oedema or varices. Nerves.—Anterior crural, arises from second, third, and fourth lumbar ; passes outside of femoral artery ; distributed to rectus, etc. Pressure on it produces cramps of inner and fore part of thigh, occurring during gestation. Obturator, from third and fourth lumbar ; emerges from obturator foramina ; dis- tributed to abductors ; pressure produces cramps of th,e inside of thigh, as head enters pelvic cavity. Sciatic, from fourth and fifth lumbar, and first, second, and third sacral; emerges by side of pyriformis ; supplies posterior part of thigh, leg, and foot; is subject to pressure during parturition, and cramps are caused in calf of leg and sole of foot; relieved by pressure and friction, sometimes very severe. The fourth sacral supplies bladder and rectum ; hence pressure produces irritation. Pudic from third sacral; supplies clitoris and external organs. Certain Muscles are also interested. Pressure upon these causes pain on motion and in defecation. Levator ani.—Origin, pubes below the brim, spine of ischium and obturator aponeurosis ; direction, by side of vagina ; inser- tion, sphincter ani. Obturator internus.—Origin, obturator ligament and around obtur. foram.; direction, tendinous around spine of ischium ; emerges by small sciatic foram;; insertion, digital fossa. Coccygeus.—Origin, spine of ischium ; insertion, coccyx. Transversus perinei.—Origin, tuber ischii; insertion, sphinc- ter ani, and vagina, and into perineum. Organs of Generation.—Divided into EXTERNAL 24 MANUAL OF OBSTETRICS. and INTERNAL, or better into FORMATIVE and COPULA- TIVE. These may be divided into, Essential and Acces- sory. Accessory.—Mons Veneris, Labia Majora, Labia Minora, Clitoris, Vestibulum, Meatus urinarius, Hymen, Fossa navicu- lars, Fourchette. Essential.— Vagina, Uterus, Fallopian tubes, and Ovaries. The term Vulva includes all the parts external to the vagina embraced by the labia majora. Pudendum is applied to the whole external genitals. Mons Veneris.—A triangular prominence of fatty tissue; situated at lower part of hypogastrium ; extent, three inches broad by two deep; covered by hairs after puberty ; composed of, adipose tissue, vessels, and nerves from external pudics, by ter- mination of round ligaments, skin, and . sebaceous glands; use, in coitus; subject to, abscesses, eruptions, excessive growth of hair. Labia majora, or Externa, are two rounded folds, which bound orifice of vulva laterally; direction, from above down- wards ; formed, externally of skin, internally of mucous mem- brane, with adeps interposed, and vessels, and nerves from ex- ternal pudics ; covered by, hairs; length, three inches ; thickest, anteriorly; in contact, anteriorly; separate, posteriorly ; their union, anteriorly, forms anterior commissure of vulva; posterior, post-commissure or fourchette ; use, to protect inclosed parts; in labor they distend greatly ; subject to, excessive development, inflammation, abscesses, eruptions, pruritus, encysted tumors, lipoma, hernia, varix thrombus, oedema. Labia Minora, or Interna, or Nymphs, are two membra- nous folds, lying between labia majora; arise, just above clito- ris ; descend ; terminate, near middle of vagina ;" shape like a cock's comb; cover, vestibulum, meatus, and part of vagina; unite, superiorly, and form preputium clitoris; composed, ex- ternally of mucous membrane ; internally of erectile tissue • in young, are smooth, rosy, and firm ; in old, flaccid and pale' in fcetal life, salient; use, supposed to be to direct the urine • do MANUAL OF OBSTETRICS. 25 not dilate in labor; subject to, inflammation, laceration in labor, enlargement, " Hottentot apron." Clitoris.—A small elevation, usually about one eighth of an inch long; situated, at the union of nymphae, the lower edge of symphysis pubis ; composed of, two corpora cavernosa, which arise from the crura of the pubes, embraced by erectores, ascend and unite below, and in front of pubes, to which a sus- pensory ligament attaches it; terminates, in a glans; covered by a prepuce, which is continuous with nymphae; is erectile ; analogue of the penis, but is imperforate ; vessels and nerves from pudic; disproportionately large in foetus; use, supposed seat of venereal gratification ; doubtful; subject to, enlargement; one case osseous: is an element in cases of doubtful sex. Vestibulum.—A triangular smooth space; bounded, above and in front by clitoris, below and behind by urethra, laterally by nymphae ; length, an inch. In this space Lithotomy. Meatus Urinarius.—A rounded opening. Situation, an inch below clitoris; diameter, one fifth of an inch, edges thick- ened. Knowledge of its situation essential in introducing catheter. Rule: Pass the forefinger into the vagina, press it gently against the symphysis, then pass an elastic male catheter along the palmar aspect directly in the median line; patient should be supine, and no exposure should be tolerated. Urethra, the urinary canal. Extends, from meatus to blad- der ; length, twelve to fifteen lines ; diameter, one fifth of an inch, but very dilatable, so much so as to permit impregnation in cases of uterus communicating with bladder ; direction, back and upwards ; variations in direction occur in pregnancy, retro- version, prolapsus uteri; separated from symphysis by lax areolar tissue; subject to, tumors, tumefaction, prolapsus. IIymen (Flos virginitatis, Clauslrum virginale).—A mem- brane partially closing orifice of vagina. Not peculiar to human female. Composed of, mucous membrane, nerves, vessels ; shape, crescentic concavity upwards, circular, cribriform; value as a test of virginity, none; other causes besides coitus may destroy ; abnormalities, imperforate, and thus prevent catame- 26 MANUAL OF OBSTETRICS. nial discharge, conception, or coitus ; dense, thick, fibrous; may embarrass parturition. Meigs thinks he has seen it at a second labor. Caruncul^e myrtiformes.—Two pairs of round red tuber- cles at orifice of vagina; supposed to be remains of hymen, but sometimes the two organs said to co-exist; use, supposed to increase capacity of vagina in labor; abnormity, excessive de- velopment. Fossa naviculars.—A depression between the orifice of the vagina and the posterior commissure of vulva. Extent, six lines. Generally obliterated by first labor. A frequent seat of chancre. Fourchette.—A sort of bridle, forming the posterior com- missure. Consists of a fold of mucous membrane, meeting the union of the labia; ruptured in first labor frequently, though not invariably. Perineum.—The musculo-membranous floor of trunk. Ex- tends from, vulva to anus; composed of, skin, adipose tissue, aponeurosis, muscles, raphe on median line; extent, from anus to vulva, one and a quarter inch, but at instant of head passing, much more dilated, four to four and a quarter inches ; use, to complete the floor of pelvis; abnormities, too broad, too thick, too narrow ; the seat of hernia. Vagina.—A membranous sheath, extending from vulva to uterus. Situation, one and a half inch below symphysis; shape, cylindroid, anterior wall concave, posterior convex; di- rection, slightly oblique upwards and backwards; lies nearly in axis of inferior strait; dimension, from four to six inches long; one in diameter of orifice; is longer in girls; widest in middle, most contracted inferiorly; anterior wall the shorter. Use to afford passage to and from uterus. Relative anatomy, ante- riorly, with urethra and bladder; laterally, with ureters, broad ligaments, sacral plexus, levator ani; posteriorly, with rectum • inferiorly, guarded by hymen; superiorly, embraces cervix uteri, forming a cul-de-sac before and behind it; of these the posterior is deeper, and hence the posterior lip of cervix feels MANUAL* OF OBSTETRICS. 27 longer; peritoneum covers superior one fifth, and is thence reflected on rectum. Assists to form, in front, the vesicovagi- nal and urethro-vaginal septa; posteriorly, the recto-vaginal septum. Inferiorly departs from rectum, leaving a triangular space. Its walls are in contact, and normally secrete mucus, in disease, give rise to " leucorrhcea." On opening, rugae are seen disposed in columns, and also transverse; most distinct infe- riorly, and in virgin ; smoother by age. Numerous follicles exist, which may become enlarged. Textures: first, mucous membrane, pink color, in old yellow or bluish, covered by tes- selate epithelium ; second, areolar tissue ; third, fibrous muscu- loid tissue, resembling that of uterus, pearly grey, one and a half Jjnes thick inferiorly, less near uterus; above resembles uterus, below is more muscular and vascular; a congeries of vessels surrounding lower 'part exists, and is called plexus reti- forme; fourth, areolar tissue; fifth, peritoneum over superior one fifth. Arteries from, the uterine, which are from internal iliacs. Veins go to plexus retiforme. Lymphatics, to hypo- gastric plexus. Abnormities, variations, in length and width, double; cicatrices, callosities, atresia, adhesion, cul-de-sac, im- perforate hymen, inflammation, malignant disease. Uterus, OoVepa, jasrpa, matrix.—A hollow viscus, the use of which is to receive, protect, and expel the product of concep- tion. Situation, in true pelvis, above vagina, below small intestines, behind bladder, in front of rectum; not to be felt superiorly in unimpregnated state, unless in very thin females, for fundus is below superior strait. Direction, of upper extremity, upwards and forwards; lower, down and backwards, Shape, like a small pear, flattened from before backwards. apex below, base above; posterior surfaces more convex, and covered throughout whole extent by peritoneum; anterior covered over superior two thirds. Divisions, into Fundus, Body, Cervix, and Os, also two regions, three margins, three angles. Fundus, that part above orifices of Fallopian tubes, a few lines high; body, between fundus and cervix is the largest; neck, below body, ten or twelve lines long; os, the 28 MANUAL OF OBSTETRICS. inferior opening in the cervix. Two regions ; anterior, smooth, polished, slightly convex; posterior, more convex. Three margins, the upper convex, assists to form fundus; two lateral margins, irregular convex superiorly; in virgin drawn out at insertion of tubes analogous to cornua of inferior animals; concave inferiorly, located between the two folds of broad liga- ment. Three angles, the two superior, formed by the meeting of lateral and superior edges, are prolonged into the tubes; inferior, results from meeting of two lateral margins. Dimen- sions, weight, in virgin, seven to eight drachms; in multipara, one and a half ounces, the result of increased nutrition; just before menstrual period, weight is increased; length, two and three quarter to three inches; breadth, two and three eighth inches; thickness, eight lines; superficies, sixteen inches. Cavity of body, shape ; triangular, superior angles leading to tubes, the apertures of which admit a bristle; capacity, about a drachm of fluid ; usually contains mucus more or less sanguinolent. Ca- vity of neck, separated from that of body by a division mark- ing "internal os uteri;" appearance in virgin, plaits, like a leaf called arbor-vitae; often disappear after delivery; shape, oval; length, eleven to fifteen lines, five to six broad ; one to two lines from front to rear. On this surface are seen ovula Nabothi, which are muciparous follicles, the office of which is to secrete the mucous plug which closes the canal of the cervix after impregnation. A viscid white of egg discharge indicates inflammation, and demands use of speculum. Os uteri or os tincce, the vaginal orifice of the uterus; appearance in virgin, transverse, smooth, regular, small, firm, thin, close, one to two lines in extent; in multipara, irregular, deformed, gaping, softer, thicker, fissured, especially on left side. Gives a sensa- tion like the tip of the nose. Most authors say anterior lip is longer, but this arises from mode of touching; in autopsies the lips are usually found equal. The os in normal state is not sensitive. Os internum sometimes closed in old. Texture. 1st. Peritoneum ; rises over bladder, covering pos- terior three-fourths of it, thence reflected from neck to uterus MANUAL OF OBSTETRICS. 29 and covers superior two-thirds, then over uterus and down over superior one-fifth of-vagina, then to rectum; laterally forms the broad ligaments ; connexion intimate above, loose below. 2d. Areolar tissue. 3d. Muscular tissue, resembling a network of fibres; color, dirty yellowish gray, with a tinge of red, but at menstrual period is deeper red (but the cavity of cervix does not participate) ; is difficult to be recognised in unimpregnated state; resembles middle coat of arteries; is unstriped; neck has more areolar and less muscular structure than body. As to muscularity, it is masked in unimpreg- nated, but manifest in pregnant state. Alleged layers are the product of dissection. 4th. Mucous membrane ; denied by some. Is not arranged in folds like mucous membranes gene- rally. Considered mucous from functions, and action during disease; ex. gr. catamenia, haemorrhages, catarrh, decidua, dys- menorrhoea, polypus. Epithelium is of ciliated variety. Functions.—First, to secrete mucus ; second, to eliminate menses; third, to develope decidua; fourth, to receive and nourish embryo ; fifth, to expel foetus. Arteries, four in num- ber, are very tortuous, anastomose frequently; ovarian, arising from aorta or renal supply of the body ; uterine, from hypogas- tric go to cervix. Veins, called sinuses ; have no valves ; empty into internal iliac; increased greatly in pregnant condition. Nerves, not yet entirely settled. Robert Lee says are very numerous; first set arising from sacral plexus distributed to cervix ; second from sympathetic. Lymphatics.—First set run to lumbar and sacral; second through round ligament into gioin ; develope greatly in gravid state. Abnormities, may be wanting, os strictured, or closed ; canal strictured ; malformations ; imperfect development; dou- ble ; displacements; flexious. Broad Ligaments (Alee vesperlilionis) are quadrilateral folds of peritoneum ; extending from uterus to sides of pelvis; divides pelvis into two compartments. Three folds; upper contains Fallop. tubes; posterior contains ovary and ligament of ovary ; anterior has the round ligament; between these 30 MANUAL OF OBSTETRICS. layer; run the vessels, nerves, and absorbents, in areolar tissue. Round Ligaments.—Two in number; arise on front of uterus, a little below Fallop. tubes; contained in anterior fold of broad ligament; direction, outwards y from below^ upwards ; termination, in areolar tissue of mons; appearance, greyish white, fibrous; length, six to seven inches; structure, as observed during gestation, contains vessels, nerves, absorbents, areolar tissue, and some striped muscular fibre. Use, to support organ forwards, prevent retroversion, a point of action during labor; does not depress uterus in coitu; are more manifestly vascular during pregnancy or inflammation ; hence over them is a good place to apply leeches; affected in malignant disease; afford an explanation of pains in groins in course of uterine dis- ease. Other Ligaments.—Anteriorly, vesico-uterine; posteriorly, recto-uterine. Are merely folds of peritoneum. Fallopian Tubes are two cylindrical canals ; calibre, various in different parts, contracted near uterus, expanded towards ovary, admit a bristle, crow-quill; shape, conical, flexuous.; situation, in upper edge or middle fold of broad ligament; extent, from lateral angles of uterus to near iliac fossa; length, four inches ; composed of, externally, peritoneum, middle mus- cular, transversely and obliquely, erectile mucous lining, ciliated epithelium ; termination, fringed, called " fimbriated extremity," " morsus diaboli," " infundibulum," has one fringe attached to ovary; is erectile; by stimulus curves over, and embraces ovary; tubes enter uterus obliquely at fundus; vascularity manifest in menstruation. and pregnancy ; function to emit ova, to transmit sfcmen ; proofs of this by Haighton's and Bi- schoff's experiments; also by tubal pregnancy ; vessels, ovarian ; nerves, hypogastric#plexus, and sympathetic ; abnormities, im- pervious, inflammation, malignant disease. Ovaries, testes muliebres.—Two oval, flattened bodies; lying in posterior fold of broad ligament, behind and below Fallopian tubes; one and a half inch from uterus on either MANUAL OF OBSTETRICS. 31 side ; length, one and a quarter to one and a half inch ; breadth, one half to five-eighths; thick, one quarter ; surface, in virgin smooth, in old numerous fissures, the result of oviposition ; superior margin is convex and loose; the inferior is straight and attached. The ligament of the ovary is a fibrous cord attaching the organ to the uterus; length, one and a half inch ; is impervious and dense. Ovary is composed of, first, peritoneum shining and exhibiting linear cicatrices; is called also '•' indusium ;" second, tunica albuginea; the proper coat is an expansion of the ligament; is dense and fibrous. It forms septa, which tra- verse the organ forming cells, in which, third, the " stroma," the true ovarian structure is found. The stroma is of pale rose color, and developes the ova or Graafian vesicles; of these, there can usually be seen fifteen to thirty, varying in size, but to microscope they are innumerable; the largest found near the surface. (The existence of " stroma" as a distinct form of tissue is questionable.) It is important not to confound the vesicles with the so called hydatids, which are frequently noticed in connexion with the ovary. Blood is supplied through the ova- rian vessels, analogous to the spermatic of the male. The nerves are from the renal plexuses. Function to supply ova, the periodical maturation of which constitutes the effective sti- mulus to menstruation. When the ovaria are removed the female loses her sexual characteristics. Subject to, entire absence, few or no vesicles, inflammation, malignant disease, dropsy, hydatid cysts, displacement. Examples show that a very small portion of, stroma suffices to afford an impregnable ovum. Menstruation is the term applied to the series of pheno- mena that attend the rupture of a Graafian vesicle; usually is said to be a periodical, sanguineous discharge from the female genitals. It is a natural function. An analogous discharge attends the period of heat in some of the inferior animals.

" Seen nothing," or otherwise " So," Flowers, Shedding. The appearance of the menses is an evidence of capacity for concep- tion, but instances of impregnation before menstruation are on record; again the discharge has been known to appear only during pregnancy. Age of appearance, usually fourteen ; varia- tions, nine years, twenty-four years. (Two cases of woman attaining forty-eight years and never menstruated, though pos- sessing sexuality, uteri, and ovaries.— Oldham.) Instances of nine months, eighteen months, two years, three years, etc. (Query.—Should girls ever marry until menstruated?) Influ- ence of climate, said to be delayed in cold, to be hastened in hot. Exceptional cases are found favoring such an opinion, but more accurate researches prove a decided uniformity of age of access. Nevertheless, extremes of climate make about three years' dif- ference. Mode of life.-^-Is later in country girls with labori- ous and simple habits ; while luxurious life, balls, plays, excit- ing books, pictures, and the use of stimulants, hasten it. Fac- tory girls, according to Whitehead, are not precocious in men- struation. Sanguineous temperament accelerates. In some families, a transmitted tendency to premature menstruation is noticed. Premonitory Symptoms, inequality of spirits, headaches, lassitude, uneasiness, weight in loins or perineum, pain in back, tension in epigastrium, pruritus of vulva, mucous discharge, dark shade under eyes, pain in thyroid body, colicky pains, skin a peculiar odor, and disposed to eruptions ; congestion of mucous membranes, as shown by epistaxis, weight. ) Fundus above pubes. r Hypogastric pro- \ j minence. 1 j Fundus at or f ' above umbilicus. ) Fundus in epigastrio.

Duration of Pregnancy.—Is usually calculated from last menstrual period ; from which 9 months are allowed, or 40 weeks, or 280 days. By females the reckoning is corrected by the first perception of motion, which is considered to be A\ months. That the duration may be less than 280 days, no one doubts ; but much controversy has arisen as to the possibility of gestation being prolonged beyond 280 days. It may be prolonged. Desor- meaux's case (singlecoitus), 9 months and a fortnight, 28*7 days ; Girdwood, 274 days; Montgomery, 280 ; Rigby, three cases of single coitus, 260, 264, 276 ; Lockwood, four cases single coitus, 270, 272, 276, 284; Lee, a single coitus, 287 days; Dewees, one coitus, 286 days; Beatty, 291 days ; Skey, 293 ; MTlvain, 293 or 296 ; Ashwell, 300; Asdrubali believes that a preg- nancy of 13 months and 22 days, and Meigs, that 420 days does not vitiate chastity. Reid gives 25 cases of single coitus ; of these labor occurred, 263rd day in 1 case ; 264, in 1 ; 265, in 1; 266, in 2 ; 271, in 2 ; 272, in 1 ; 273, in 1; 274, in 6 ; 275,in 2 ; 276, in 3 ; 278, in 1; 280, in 2 ; 287, in 1; 293, in 1. Dr. Reid, in another table, gives 500 cases of the days inter- vening between the last menstruation and labor, of these 23 terminated in 37th week; 48 in 38th; 81 in 39th; 131 in 40th ; 112 in 41st; 63 in 42nd; 28 in 43rd; 8 in 44th; 6 in 45th week. Merriman's tables of 114 cases show that the greatest pro- portion terminate in the 40th week ; a considerable number in 41st. Murphy, 182 cases; in 39th week, 24 ; in 40th, 25 ; in 41st, 32 ; in 42nd, 25. In the case of animals, where accurate records are practicable, considerable variations occur. Diseases of Pregnancy.—May be regarded under two heads, ls^. THOSE OF WHICH PREGNANCY is the cause. 2nd. DISEASES MODIFIED by pregnancy. Are mostly of 1st class. Ordinarily, are aggravations of ordinary symptoms. MANUAL OF OBSTETRICS. 77 The sympathy between uterus and stomach is well marked even in the unimpregnated state, for uterine derangements have usually dyspeptic symptoms. Of the gastric phenomena the most marked is Nausea.— Occurs usually about fourth to sixth week. Con- tinues six weeks to two months ; not usually after four months. Variations, throughout; very soon after conception ; not till seventh or eighth month; sometimes not till after meal; at bed-time; in night; all day ; not at all; only from special articles. Character, occurs on assuming erect posture ; some- times nausea without vomiting; lasts from ten minutes to an hour; appetite undiminished. Bad effects.—Miscarriage; want of nutrition may cause sinking; death. Good effects: Prevents formation of too much blood. Nature of fluid : Thin, watery, glairy, colorless, bile, blood, greenish or blackish, excessively acid. General Symptoms : Reduction of strength ; pain in epigastrio ; loaded tongue ; constipation. Causes : In mild cases by sympathy ; towards end from pressure ; in violent by gastritis; sometimes odors, indigestible food, articles that readily acidify, acescent vegetables, salt meats; torpid bowels the great cause. Treatment.—First regulate diet, then use cathartics ; if these fail use anti-emetics. If plethoric or pain on pressure over epigastrium, with dry red tongue ; leeches and blister, purga- tives, seidlitz, magnesia, mass. hyd. and hyoscy., ext. coloc. comp., salines. Counter-irritants, &c, to epigastrium : blister, sinapisms, hot turpentine and flannel, cloth\s wet with lauda- num, mint poultice, spice plaster. Narcotics.—Avoid constipation ; effervescing draught with T. opii or sol. morph.; starch and laudanum enema. If add, use alkalies, and if these fail, use acids ; charcoal 3j, every two or three hours with or without soda or magnes., charcoal and milk, lime-water and milk. Anti-emetics: Hy- drocyanic acid, kreasote, strong coffee, clove tea, 20 to Oss, ice, soda water, spearmint tea, ol. tereb., infus. calumbae, mineral acids with bitter infusions, trisnit. bismuth., tinct. nuc. vomic, 78 MANUA.L OF OBSTETRICS. acet. plumb, et morph. Diet: Lightest kind ; no stimulants ; very little at a time; observe if stomach will bear better at some period of the day ; solids sometimes best; quantity small, and position supine; sometimes total abstinence for 24 hours; sometimes a single article, cold arrow-root, gum arabic, iced water and cracker ; lemonade ; food cold ; champagne. In later months, the only resource is horizontal posture. If all remedies fail and life is jeoparded, excite premature labor. Dubois, in thirteen years, met with twenty fatal cases. Au- topsy revealed no lesion. When gestation is arrested spon- taneously or artificially, the vomiting ordinarily ends. Ho says: Do not perform it whexi the signs of extreme exhaustion are present, as loss of vision, cephalalgia, coma, somnolence, and mental disorder. Abstain from operating when the vomiting, though violent and frequent, allows some aliment to be retained, when the patient, though wasted and feeble, is not obliged to keep her bed, when the suffering has not yet induced intense and continuous febrile action, and when other means still remain untried. The proper time is marked by, 1st. Al- most incessant vomiting, by which all alimentary substances, and sometimes the smallest drop of water, are rejected. 2nd. Wasting and debility, which condemn the patient to absolute rest. 3rd. Syncope, brought on by the least movement or mental emotion. 4th. A marked change in the features. 5th. Severe and continuous febrile action. '6th. Excessive and penetrating acidity of the breath. 1th. Failure of all other means. Stoltz relates four cases, three of which proved fatal, the other was saved by the operation. He advises a timely interference. Nutritious enemata will sustain life for a long time. Transfusion might be demanded. Emetics will frequently cause abortion, while puerperal nausea rarely does. Heartburn.—Cardialgia, pyrosis, water-brash. Occurs frequently; sometimes quite early; usually not troublesome till last months ; often in hysterical and nervous. MANUAL OF OBSTETRICS. 79 Causes.—Sympathy; certain articles of diet; some say alteration of gastric juice ; bile in stomach ; affection of eighth pair of nerves ; mental emotion. Symptoms.—Pain and heat in epigastrio, extending along oesophagus; eructations of sour and bitter fluid; aggravated by eating ; sensation of dragging from stomach towards spine; fluid bilious, clear, bitter, acid, acrid ; usually no constitutional disturbance; appetite impaired. Diagnosis from inflammation of oesophagus and stomach by absence of fever, also is intermittent. Pregnancy a presumptive proof of heart-burn. Treatment.—Diet, exercise, attend to bowels. One article of food, rice, oysters, milk, stale bread, sweet butter, ship-bread. Counter irritation to epigastrium, blister, anodyne liniment. Antacids.—Magnesia, ammonia, aq. calcis, carb. soda, liq. potass., mis. cretse. The unlimited use of antacids is objection- able ; magnesia may accumulate. Acids.—Citric, elix. vitriol, ice water, soda water. Attend to bowels; give mist, eccoprot., magnes., ext. coloc. comp. May require opium. Mild bitters in enfeebled. Trisnit. bismuth. Constipation.—A very common attendant. Duration : days, weeks, or months. In slight degree, inconvenient only; if prolonged, is injurious. No woman should be permitted to fall in labor with constipated bowels. Causes.—Pressure, altered vitality. Attendant phenomena.—In slight cases, uneasiness, discom- fort, headache, increased heat; sometimes small, liquid, daily stools, and yet accumulation. If prolonged, headache, sleep- lessness, restless, sense of weight and fulness, irritability, nausea, vomiting, pains in abdomen, irritation of mucous membrane, tenesmus, bloody mucous discharges, scybalse, false pains, abortion from straining, per vaginam can feel enlarged rectum, and sometimes a channel. Always inquire in the diarrhoea of pregnancy whether constipation has preceded.

DIARRHCEA.—Not so frequent as constipation. Those costive before pregnancy may be loose; vice versa ; constipation may precede; alternate, or co-exist. Occurs at any period; often an early symptom of preg- nancy. Causes.—Constipation, quasi vicarious of menstruation; cold ; emotion ; intestinal irritation. Phenomena.—Varieties in frequency and character of stools; watery, dark, offensive, acrid, pain, tenesmus. General symptoms, in slight cases, languor, no fever; but in severe, especially if ulceration exists, great pain, burning sensa- tion, quick pulse, dry tongue, hot skin, great thirst, anorexia, vomiting, frequent offensive stools. Sequences.—Oftener than constipation it causes abortion, especially about third month ; arises from tenesmus. Treatment.—Not always wise to stop suddenly, especially if periodical.

Occurs in hysterical and nervous; in robust and plethoric; in early months is usually nervous'; in later ones, from plethora. Causes of nervous, mental emotion, food, constipation, MANUAL OK OBSTETRICS. 81 fatigue. Of Plethoric: errors in diet, stimulants, warm bath, exertion. ^ Seat over part or whole : hemicrania, megrim,' migraine; in vertex, occiput. Kind of pain : constant, paroxysmal, dull- aching, acute throbbing; without or with intolerance of light and sound. In plethoric, pulse quick, full, strong, carotids throbbing; face flushed; eyes bright or suffused; eyelids heavy ; photo- phobia. Pain dull or acute, over eyebrow; constipation may complicate either form, and then tongue is loaded, and bad taste in mouth. Prognosis.—In Nervous, not dangerous ; in Plethoric, to be guarded. Treatment.—In Nervous, Valerian infusion or Tine. Valer. Ammon., Hyosc. et Camph., Hops, Hop-pillows, Ether, Chloroform, Cologne, Blister behind ear. Brisk purge. In Plethoric.—Venesection, Leeches, Antiphlogistic, Blister to nape. Special attention to diet and exercise. Plethora.—A certain amount is normal, and needs no attention beyond a moderated diet and active exercise. If more marked, use purgatives; ipecac. \ gr. 3 times a day. If manifested by headache, somnolence, flushes of heat, vertigo, dyspnoea, depressed spirits, high colored urine, and full frequent pulse ; or by indications of uterine hyperemia, as sensation of weight in pelvis, groins, and thighs, tension, &c.; small venesections may be practised ; if the uterine symptoms indicate threatening abortion, opiate enemata and venesection. Leeches are objectionable. Piles.—Hemorrhoids ; are frequent. All the different forms are found. Occur : in relaxed, indo- lent, constipated. Exciting cause : pressure of uterus. Period : in early months, or in last, and again after delivery. Attendant Phenomena.—Itching, weight; if inflamed pain, throbbing, heat, bearing down, pain in defecation, motion distresses, tenesmus, bloody discharge. 7 82 MANUAL OF OBSTETRICS. Rarely curable during pregnancy. Treatment.—Open bowels; Sulphur, Bitart. Tot., Confect. Senn., Coloc., Mass. Hyd., Enemata. Diet: bland without stimulants. Anodyne lotions or ointment to external; return if possible; sometimes incision. If inflamed.—Poultices; astringents; cold lotions; cold semicupia. Avoid operations until after labor. 02dema.—Is frequent. Most in latter months. Extent: Feet, legs, thigh^ vulva, hips, face. Cause : Pressure upon veins. Sometimes from renal con- gestion, then albuminuria exists; such dropsy manifests itself be- neath the eyelids and upper extremities, and should always ex- cite apprehension lest convulsions should succeed. Effects: Are mechanical, interfering with motion ; or if in labia, with labor. Relieved by horizontal posture. Sometimes complicated with Eclampsia, Erysipelas, or even gangrene from over-distension. Always examine urine if oedema of face is noticed. Treatment: Rest, salines, diuretics. If extreme.—Punctures, cold water, saturnine lotions. If albuminuria.—Local depletion over kidneys, saline purga- tives. Toothache.—Odontalgia ; not uncommon. Occurs .in early months. Sometimes an early sign of preg- nancy. May be continued or paroxysmal. Causes : Neuralgia ; Gingivitis ; Catarrh ; Carious tooth ; Constipation ; Breath is acid, reddens litmus. Diagnosis: Whether from caries or merely sympathetic; pregnancy is a presumptive proof of neuralgic character. Treatment: If neuralgic.—Oils of Cloves, Mint, or Cinnamon, &c.; Tannin, Kreasote, Stramonium, Valerian, Blister. Tine. Aconit. beneath ear is very effectual. If inflamed gums, scarify, leeches, warm water, purgative*. MANUAL OF OBSTETRICS. 83 Main point of interest is as to extraction. Authorities differ. Usually will not do good, and is likely to produce abor- tion. Dyspncea.—Occurs sometimes in early from sympathy; at quickening ; more in latter months from plethora and mechani- cal cause ; most in primiparae. Also from cardiac or thoracic disease, tumors, &c. Treatment: In early.—Antispasmodics ; Valer.; Ammon.; Ether. If from congestion, VS. ; purgatives ; Ant. Tart.; Ipecac. Mechanical; position. Attend to bowels. Avoid flatulent food. Cough.—Occwrs sometimes in early months from sympathy ; in latter, from pressure. Thoracic diseases. In early: No expectoration; pulse unaltered; no feverish symptoms; subsides spontaneously. In latter : The mechanical succussion may cause premature labor; shown markedly in influenza ; loss of rest and headache also demand interference. Diagnosis: By stethoscope. Treatment: In early.—Antispasmodics ; narcotics; bowels free. In later.—Venesection; Ant. Tart.; Ipecac. Diet: Avoid flatus. Palpitation.—Very common, especially in hysterical. Occurs just after conception ; at quickening; towards close. Causes : Sympathy ; pressure ; mental emotions ; disordered stomach ; flatus ; foetal motions. Treatment: In paroxysm.—Antispasmodics, Valer., &c.; Ether; Chloroform ; Opiates ; Sinapism between shoulders. If plethoric.—VS. In interval.—Iron ; antispasmodics ; posture ; exercise; dress not to bind. Vertigo, and dimness of vision, and faintings, are frequent. Arises from nervous susceptibility or .from plethora. Some women easily affected by moral emotions, as joy, anger, odors, unpleasant sights, foetal motion. Syncope attacks while standing, tinnitus, vertigo, dimness of 84 MANUAL OF OBSTETRICS. vision, weakness of knees. Sometimes yawning, sense of heat, chills, pulse and respiration nearly cease*. Relieve by Ammonia, cold water, horizontal posture, wine and water, &c. Incontinence of Urine.—Enuresis.— Occurs early from pelvic irritation. In latter months, from pressure, especially in ample pelvis. Coughing causes expulsion. Treatment: In early.—Fomentations ; leeches; Belladonna ; Hyoscyamus ; Lupuline ; astringents. In latter.—But little can be effected; cold sponging; eva- cuate bladder frequently to prevent involuntary expulsions. Dysuria.—Caused by irritation ; pressure; paralysis; piles; calculus ; tumors ; displacements. Diagnosis : By vaginal examination. Treatment: If from irritation, leeches, anodynes, mucilagi- nous drinks, fomentations ; if from piles, leeches ; from over- distension, inf. Uva Ursi; if from compression, position; too pendulous belly, a bandage; catheter. Pruritus.—Sometimes excessively distressing. Dewees found a few cases to arise from aphthae. Treatment: Sol. Bibor. Sod. 3j.—iij. to Oss. If dry and red excoriations, dry Calomel; Decoct. Papav.; Acet. Plumb.; Sol. Alum ; Sol. Sulph. Zinc.; cold water; Sol. Nit. Argent, grs. v.—x. to 3j.; Ung. Cor. Sublim.; Sol. diacet. Plumb, tepid.; place compress wet with solution between labia ; chloroform ointment. Internally.—Pil. Plummeri; Elix. Vitriol; Ilyoscy.; Cicuta. Icterus.—Jaundice usually in latter months from pressure. Sometimes in early from sympathy. Sometimes preceded by digestive derangement; vomiting; weight in epigastrio. Treatment: Keep stomach and bowels free. Position on left side. Insomnia.—Sleeplessness; agrypnia; pervigilium. Not un- common. Most in hysterical. Sometimes in early, most in latter months. Causes : Nervous; hot bed-room ; too little exercise; foetal motion ; plethora. MANUAL OF OBSTETRICS. 85 Treatment: Cold bathing to head ; pediluvia (sometimes cause abortion) ; laxatives ; mild anodynes ; small venesection ; avoid stimulants, tea and coffee ; light diet. Free air and exercise ; sponging body at bed-time. Cramps.—Are frequent and annoying. Most at fourth and fifth month, and at latter end. Causes: Mechanical ;• muscular distension; stretching of ligaments ; constipation ; fatigue ; pressure on nerves. Situations: Along crista ilii; in symphysis, from round ligaments ; in lumbar muscles, coccyx, sacrum ; in inferior ex- tremities, anterior and inner part of thigh from anterior crural nerve; in sciatic, along calf, heel, and sole; in large pelvis, pains are severe ; interfere with walking; cause falls. Treatment: Frictions ; position. Retroversion of the Uterus.—Infrequent. May exist also in unimpregnated. The os is close behind symphysis pubis; fundus in hollow of sacrum ; posterior wall of vagina is depressed, anterior carried forwards. Occurs in those a short time pregnant; while uterus is yet in pelvis ; before 18th week. Either sudden or gradually. Causes: Large pelvis ; projecting promontory of sacrum ; most in thin women ; moles; tumors ; scirrhus; distended bladder; enlarged ovary. Excited by violent efforts, vomiting, defecation, falls, blows. Symptoms : One of most prominent and distressing is reten- tion of urine (hence in dysuria of early pregnancy always suspect retroversion) ; difficulty in defecation ; both these are aggravated by efforts; weight and fulness of pelvis; bearing down ; dragging pain in groins. If not relieved, violent pain, febrile symptoms, vomiting, peritonitis ; fatal by irritation, in- flammation, or sloughing. By examination vagina is directed forwards, posterior wall in folds, anterior stretched, a tumor stretching across pelvis. Sometimes Retroflexion, i. e. the os in situ, but fundus depressed, making uterus " retort shaped ;" not in pregnancy. Diagnosis: From ascites, by effect of catheterizing; from 7* 86 MANUAL OF OBSTETRICS. ovarian enlargement, by suddenness and form of tumor; from tumors, by shape, position of cervix. Per rectum examination valuable. Treatment: First, use catheter, male elastic preferable; if silver, direct backwards. Second, open bowels; Chloroform. Then begin with two fingers in vagina to pull down cervix; two in rectum to push up fundus. The supine position failing, place on hands and knees. Insert a bladder into rectum and inflate it After reduction, keep patient on her side for some time; evacuate bladder frequently, and always stoop forwards in doing so. When the uterus rises above the promontory, this accident will not recur. If uterus continues unreduced, inflammation is excited, adhe- sions form, and the attempts at restoration are hazardous. If reduction proves to be impossible, it has been proposed to puncture membranes through os and procure abortion ; or even through uterus. Gastrotomy proposed as a last resort. Anteversion.—Fundus at symphysis ; cervix in sacrum. Is rarer and less serious than retroversion. Causes: Empty bladder, relaxed abdomen, and some sud- denly applied force; faecal accumulations; chronic metritis; fibrous tumors ; fall; diarrhoea. Symptoms: Retention of urine rare; constipation occasional; weight; pain. Examination detects position of fundus and cervix. Diagnosis: From Stone by sound; from Retroversion, tumors, and ovarian enlargement, by vaginal examination. Treatment: If slight, relieves itself. Hook down cervix and elevate fundus. Retroflexion and Anteflexion rarely concern the pregnant state. Anterior Obliquity of Uterus.—" Pendulous belly" is of consequence in labor. Influence of Gestation on Disease.—Two aspects.— Are pregnant women more or less susceptible of epidemic dis- MANUAL OF OBSTETRICS. 87 eases ? Does pregnancy aggravate, accelerate, or retard existing disease ? Pregnant women are not generally so subject to epidemic diseases, but sometimes are more so, and then the proportionate mortality is greater. On existing disease.—On acute diseases is unfavorable, for 1st. The vascular system is additionally excited. 2nd. The foetus is liable to be affected, and then abortion occurs under most unfavorable circumstances. 3rd. The treatment required to subdue inflammation is liable to produce abortion. . Hence, in acute diseases, treatment must be moderate but decided. Venesection should be used decidedly, but not re- peatedly. Emetics are hazardous. Purgatives of a drastic character should be avoided. On chronic, is not so prejudicial. Phthisical women conceive readily, and do not abort proportionably. Phthisis was sup- posed to be retarded by pregnancy. Grisolle, however, proves otherwise; the issue is precipitated; and Dubois' experience confirms this. The children of phthisical women are not im- perfectly nourished. Phthisical women go to full term. On aneurism and cardiac disease : Pregnancy is prejudicial; dyspnoea is increased during pregnancy, and in parturition there is danger. Regimen of Pregnancy: Diet should always be light, espe- cially in the first and last months; flatulent food should be avoided. Though no foolish concessions need be made to " longings," a woman's dislikes should be regarded. Atmosphere : Low, damp, miasmatic situations to be avoided. Exercise to be regularly taken daily in open air; walking best. Dress: Avoid all tight dress, especially over breasts and around waist. Changes in the Ovum.—The ovum progresses towards the uterus, under the ciliary influence, together with the mus- cular action of the tube, occupying seven or eight days at least in transitu. It acquires in the tube an albuminous envelope, which, uniting with the zona pellucida, forms the Chorion. 88 MANUAL OF OBSTETRICS. The ovum has three envelopes, Chorion, Tunica Media, Amnion ; has also as accessories the Umbilical Vesicle, Allantois, Placenta, and Cord. CHORION.—Situation: The most external covering. Cor- responds to the membrane lining the egg-shell; evident soon after reaching uterus. Has two surfaces. Inner smooth. Ex- ternal covered with short cylindrical villi spongioles; these are solid, and frequently terminate in knobs. At about two months these villi begin to disappear from the general surface, and aggregate at the spot where the chorion comes in contact with the uterus ; opposite to this spot the cord forms on the inside, and here is the future placental site. Divided into two laminae, which are well seen over placenta ; outer is exochorion, inner endochorion ; more properly into an indefinite number. Structure: Is said to be destitute of vessels, nerves, or lym- phatics. Is developed thick, becomes thinner gradually, re- maining thickest over placenta. Is separated from amnion by a gelatinous layer, which condenses into a thin membrane called Tunica Media. Between these a fluid sometimes exists in con- siderable quantities called "false waters ;" successive discharges of this constitute " Hydrorrhcea." Abnormities: Inflammation; vascularity; thickening; false membranes; " vesicular mole." UMBILICAL VESICLE.-VESICULA ALBA.—Situation : In interspace between amnion and chorion. Exists only before third month. Analogous to yelk, but unlike it is uot ultimately inclosed in abdomen. Communicates with intestinal tube, upon which it lies. Shape : Rounded or oval. Size of small pea. Progress: The small end becomes narrow and forms a canal; this gradually becomes impervious and threadlike at about two months ; it shrinks, and remains flattened out along cord. Contains a yellowish, white fluid with granules and a few globules. Composition: An external vascular layer and an inner mucous. Vessels: Omphalo-mesenteric artery and vein. Use: To contain nutriment for embryo before placenta is formed. MANUAL OF OBSTETRICS. 89 ALLANTOIS, is a delicate membranous sac of an elongated form ; arising from caudal extremity of embryo; lies between chorion and amnion. It is observed on 10th day, and grows rapidly ; the base soon becomes applied to the chorion. As the mucous layer is closing to form the intestine, the sac be- comes constricted into two portions; that within the body contains the urinary bladder : the portion between it and the umbilicus is the Urachus ; the part beyond is the Allantois ; through the urachus the urine in early embryonic life can pass; subsequently it becomes impervious. AMNION.—Amnios, the envelope nearest the foetus ; " is formed by the inner lamina of the fold, of the cephalic and caudal hoods which constituted the external serous layer of the blastoderma around the embryo; is continuous with the margins of the ventral opening; its internal surface exhales a fluid in which the embryo floats." Structure, thin and trans- parent, but firm and resists laceration; externally flocculent, internally smooth; as yet vessels and nerves not recognised. Relation to fatus, early is close, later separated by liquor amnii. Is continuous with abdominal integument of foetus. From outer coat of cord. Abnormities.—Inflammation, thickening. Liquor Amnii.—" The waters." A fluid contained within, and secreted by, the amnion. Quantity: at first proportionately greater than foetus, afterwards exceeded by it; at term about one pint, may be quarts. Contains, water, albumen, albumi- nate of soda, chloride of sodium, phosphate of lime, lime, extractive matter. Source: some say from mother, others foetus, others both. Color: at first pellucid, becomes milky from intermixture with epithelium of foetus, also viscid and unctuous ; may be greenish, grey, yellowish, blackish. Taste : saltish. Odor: peculiar, disagreeable; sometimes is acrid. Uses : 1st, said to be for nutrition during early months. 2nd, preserves an equable temperature to foetus. " 3rd, diminishes shocks, allows motion to foetus. 4th, prevents pressure on cord. 5th, acts as wedge during labor and lubricates passages. 0 th, facilitates operations. 90 MANUAL OF OBSTETRICS. Abnormities.—Scanty, excessive, and delays labor; " dropsy of amnion." Variety, in color, yellow, brown, red, green, black. From dead foetus offensive and sanguinolent PLACENTA.—(From irXaxug broad.)—The organ of hema- tosis for the child ; a spongy vascular mass ; is a flattened body, about 6 to 8 inches in diameter ; £ inches to 1^ thick at centre; tapers to the edge. Circumference: 18 to 24 inches. Shape: oval or rounded, battledore. Weight: usually a pound or more. Is usually single, very rarely double for a single foetus. Two surfaces : Internal or Foetal, and External or Uterine, or Maternal. Internal or Foetal: is smooth, shining; marked by radiations of vessels; covered by, 1st, chorion which is firmly attached, and sends processes between lobules. 2nd, by amnion nearest foetus, is loose. Outer, Maternal: is uniform but not smooth ; is covered by decidua serotina; when this is separated are seen the lobules or cotyledons, between which the decidua serotina send processes; the vessels of one lobule do not communicate with those of another. Situation: any part of uterus, usually at fundus, mostly on left side, anteri- orly or posteriorly; can be ascertained by stethoscope; verified by observing the part of membranes ruptured. Period of development.—Does not begin till end of first month. Structure.—The villi of the chorion that are in contact with the decidua increase, develope, interlace, and become inclosed by septa of the developed decidua which receive them ; thus are constituted the foetal and maternal portions of the placenta which form in the human subject an indivisible mass, while in the bitch they are separable. The two fcetal arteries, emerging from the umbilicus, subdi- vide infinitely, and extend as capillaries into the villi, and here loop over and become venous capillaries, which converge, and form the umbilical vein. By examinations from without inwards, the uterus at the site of the placenta is found to con- sist of large cells or sinuses, which inter-communicate freely, MANUAL OF OBSTETRICS. 91 but do not pass beyond a membrane, the decidua serotina; into these cells, which are the uterine sinuses or veins, the blood is poured by the curling uterine arteries terminating in a capillary extremity. Into these cells from the placenta are intruded the capillary vessels of the foetus covered by the decidua serotina, but no vascular inter-communication exists between the mother and the foetus. At this part where the capillaries of the foetus and the maternal vessels are in close contact, two sets of nucleated cells are said to exist, one belong- ing to the maternal portion of the placenta, the other to the foetal; between these two a space exists in which the materials secreted by the maternal cells are poured out and absorbed by the fcetal cells. Abnormities.—Malformations, displacement. May be seat of congestion into substance, on surfaces, between membranes. Inflammation (placentitis), which may attack one or more lobes, resulting in adhesion, pus, death of foetus, and abortion. Hypertrophy of part or whole; atrophy; cartilaginous or calcareous deposits ; fatty degeneration ; vesicular mole. UMBILICAL CORD.—" The cord," funis umbilicalis, na- vel-string. Is the connecting medium between foetus and placenta. Composed of two arteries, one vein, gelatine of Wharton, fine areolar tissue, a sheath of amnion externally; in embryonic life the duct of umbilical vesicle, urachus, omphalo- mesenteric vessels, and a portion of intestine (hence umbilical hernia). Visible, about end of first month; at first is thin and cylindrical, the vessels straight; between 3rd and 9th week appears like two vesicular swellings; after this the vessels run spirally, the arteries around the vein from left to right; swellings like knots exist on some cords, and sometimes com- plete knots are formed. Length, varies from 8 inches to 67 inches ; average 18 inches. Some cases on record of 5 or even 2 inches. The vein has no valves; its calibre equals that of both arteries. The arteries are branches of the fcetal internal iliacs; doubt of existence of lymphatics and nerves. Position, usually 92 MANUAL OF OBSTETRIC*. above head of child ; variations, before head, around a limb, around neck (one case in 9 or 10), sometimes causes delay in labor, sometimes strangles child. Continues to pulsate some- times 15 or 20 minutes after birth; even more; is weakest 3 or 4 inches from umbilicus. Abnormities.—1st, vessels may divide before reaching placen- ta. 2nd, two veins and one artery ; one of each ; three arteries. 3rd, two cords and one child. 4th, knots which by being drawn during labor may stop circulation. 5th, vessels closed. 6th, absence of funis and umbilicus. 1th, insertion into some other part of foetus than umbilicus. Sth, may contain a portion of intestine. 9th, communication between two cords in twins. 10^, inserted into wrong part of decidua. 11th, twists im- pairing nutrition of foetus. 12th, varicose or hydatidic. 13th, coats rupture and hemorrhage. 14th, torn by falls. In some cases a limb has been found almost, in some quite, amputated, by the encircling cord. The Embryo.—The ovum exists before impregnation; then is called embryo till third month; fcetus, as long as in utero; child, or infant, after birth. Resuming the account from page 62, " The germinal membrane consisting of a layer of epithelium-like cells, incloses the yelk, lying in contact with the internal surface of the zona pellucida. Soon after its formation there is produced on its surface an opaque spot, the germinal area, and here the embryo is first developed. About this time the germinal membrane becomes divisible into two layers. The superior or external lies next to the zona pellucida, and is called the serous layer, from it are developed the organs of animal life, e. g. bones, muscles, and integument; the inferior or internal division in contact with the yelk itself is called the mucous layer, and forms the viscera. At first the area germinativa is rounded, but soon becomes oval, then pear-shaped, and during this change there appears the area pellucida, and between the mucous and serous layers, the area vasculosa, from which the blood-vessels are formed. The first trace of the embryo in the MANUAL OF OBSTETRICS. 93' centre of the area pellucida is a groove, the nota primitivaj formed in the serous layer, it is wider at the anterior or cephalic extremity, and tapers towards the other extremity. Coincidently with the primitive groove are formed two oval masses of cells, one on each side of the groove, the lamince dorsales ; these rise into two prominent masses, turning their edges inwards over the groove. Their form changes from oval to pyriform, and finally guitar shape. The inner side of each of these masses adjoining the groove becomes' pellucid and developes into nervous substance. The parts from the opposite sides unite and form a tube, which is the central canal of the cerebro-spinal axis; the nervous matter becomes the rudi- mental spinal cord, and these are the first parts developed. Three cerebral vesicles are formed before the primitive groove is closed over; the upper dilating into three pouches; the caudal extremity of the groove dilates into a lancet-shaped pouch corresponding to the cauda equina. The closure of the canal by the nervous layers begins at the middle, and at the same time the other parts of the laminae dorsales unite and form the rudiments of the head and dorsal part of the body. Immediately beneath the groove is seen a linear mass of cells, the chorda dorsalis, around which the vertebral column is developed. The earliest indications of vertebrae are in square plates. While the dorsal laminae are closing thick prolonga- tions of the serous layer are given off from the laminae ven- trales ; these bend downwards and inwards towards the cavity of the yelk, where they unite and form the anterior walls of the trunk. During these changes the area vasculosa forms, which may be considered the third or middle layer of the germinal membrane. At the circumference of the area isolated red spots are seen, which soon unite and form vessels ; the margin of the vascular layer is at first circular, and bounded by vessels united in the circulus venosus. About the same time the heart is formed by the vascular layer bending down from the cephalic extremity so as to inclose the anterior part of the cavity of the body. The blood-vessels are developed from 8 94 MANUAL OF OBSTETRICS. nucleated cells, which send processes, unite, and thus produce a net-work. From this net-work in the area vasculosa, vessels extend into the area pellucida and join the incipient heart, which is at first a tube, prolonged inferiorly into two venous trunks, and superiorly into three or more aortic arches, which unite beneath the vertebral column and form the aorta. At first the aorta divides into two branches, the omphalo-mesenteric, which terminate in the sinus terminalis, and thence the blood is returned by the omphalo-mesenteric veins. Finally the sinus terminalis disappears and vessels cover the yelk-bag. Meanwhile the embryo becomes boat-shaped ; the cephalic end bends down and forwards, the germinal membrane follows, and a fold is produced called involucrum capitis. Soon after another fold of the membrane is formed at the caudal extremity and presses from behind forwards. These two folds are connected by that part of the embryo which passes off from the structures of the axis on each side into the expanded germinal membrane. Thus the embryo is separated by a construction anteriorly, posteriorly, and at sides, from the rest of the germinal membrane; the cavity is turned towards the yelk. The internal layer of the membrane forms the intestinal canal; the external layer subsequently developes into the walls of the neck, chest, and abdomen. Gradually the cephalic, caudal, and lateral edges rise and extend over the body from the abdomen to the back, meet, coalesce, and inclose the embryo in a sac— the amnion. The inner of the two layers forms the amniotic sac, the inner lines the internal surface of the chorion. The amnion is continuous with the skin at the umbilicus, which at first is wide, and gradually closes. The inner layer of the germinal membrane remains continuous with the intestinal canal; the constricted part is called the omphalo-mesenteric duct; the inner layer having at this period extended over the whole yelk has become the umbilical vesicle. By the con- striction at the umbilicus the body of the embryo becomes mostly detached from the umbilical vesicle, though the cavity of the intestine still communicates with it through the duct. MANUAL OF OBSTETRICS. 95 The yelk sac contains nutriment for the embryo, but its func- tion ceases early. On the walls of this sac the omphalo-me- senteric vessels ramify; an artery and two veins. While the vesicle is forming a pear-shaped mass of cells projects from the caudal extremity of the embryo and becomes the allantois, upon the walls of which the future umbilical arteries and vein develope. It grows rapidly, reaches the chorion, in the villi of which the umbilical vessels unite in the formation of the placenta. As the abdominal cavity closes, the allantois becomes constricted into two portions, the larger proceeding to the chorion, the less is retained in the abdomen, and becomes the bladder ; the constricted part between the two is the urachus. DIMENSIONS OF EMBRYO.—About the third week, it is oblong, swollen in the middle, obtuse at one extremity, and pointed at the other, somewhat curved forwards; color, greyish white; consistence, gelatinous; length, two to four lines; weight, one to two grains. The head appears as a small tubercle, separated from the body by a notch. No extremities seen. It is surrounded by the amnion. The abdominal cavity is open ; the heart is beyond it, consisting of a single auricle and ventricle. At fifth week: Head has greatly increased; eyes seen as two dark spots ; superior extremities seen like two obtuse teats; length, two-thirds of an inch; weight, 15 grs. The funis can be seen; the inferior extremities seem rounded pimples; the divisions of the vertebrae can be seen. Heart, interventricular septum seen, but incomplete. Lungs seen as five or six lobules, in which bronchi terminate in cul-de-sacs. The Wolffian bodies, or temporary kidneys, constituted of an excretory canal, are seen along the vertebral column, extending from the lung to the pelvis. Alongside of this canal is seen another tube, which becomes either the oviduct or vas deferens. Early in life are seen on the neck four fissures analogous to branchiae, and to these the aorta sends four branches, but they become obliterated, and the vessels become the arch of the aorta and pulmonary artery. One branchial fissure is con- . 96 MANUAL OF OBSTETRICS. verted into the external ear. The upper jaw is composed of two pieces, which close. The nostrils are separate; and if de- velopment is arrested, hare-lip follows. At seventh week : Ossification seen in clavicle and lower jaw. The intestine still extends into the funis. The omphalo-mesen- teric canal is almost obliterated. The anus remains closed. Kidneys and capsulae renal es begin to appear, and soon after the sexual organs. Bladder is seen as a tumor- continuous with urachus. Length of embryo, one inch. At two months : Forearm and hand seen, but not the arm; no fingers. Funis not spiral, four or five lines long, inserted low. Organs of generation seen, but difficult to discriminate from length of clitoris. Embryo 1^ to 2 inches long; weight, 3 to 6 drachms ; head forms about one-third. Eyes seen, not covered by lids ; nose an obtuse eminence; nostrils round and separate ; mouth gaping. Epidermis distinguishable. At tenth week: Length, 1 \ to 2\ inches; weight 1 ounce to \\. Eyelids cover eyes. Lips develope. Parietes of thorax seen, and heart no longer visible. Fingers distinct, but at first are webbed. Funis becoming spiral, still contains intestine; not inserted so low. At end, of third month : Weight, 3 to 4 ounces; length, 5 to 7 inches. Eye-ball seen through lids, membrana pupillaria seen. Forehead and nose seen ; lips well marked. Funis con- tains no intestine ; spiral turns well seen. Nails appear. In- tegument rosy. Sex distinct. At fourth month : Embryo becomes foetus. Length, 6 to 8 inches ;,weight, 7 to 8 ounces. Fontanelles large, as also are sutures. Hair seen on head. Eyes, nostrils, and mouth are closed.

At six months: Length, 11 to 12£ inches; weight, 1 lb. Hair seen longer and thicker. Nails solid. Scrotum small, red, and empty. At seven months : Length, 12$ to 14 inches. All parts more MANUAL OF OBSTETRICS. 97 developed. Membrana pupillaris disappears. Palpebrae partly open. Descent of testicles begins. At eight months : Length, 16 to 18 inches ; weight, 4 to 5 lbs. At term: Length, 19 to 23 inches; weight, 6 lbs. to 7 (average) ; 10, 11, 12, occur, and even 16 alleged. Secretion of Bile: Noticed at about five months, and con- tinues. Meconium : A dark green, semi-fluid substance, existing in the foetal intestines. At an early period the intestinal canal contains but little fluid ; about third month more abundant secretion occurs. Before fifth month the meconium exists in small intestine only, and is greenish brown ; after that it accu- mulates in large intestine and becomes darker. It is a mixture of bile with the products secreted by the mucous membrane; said to be digested liquor amnii. Urine : Never entirely fills bladder at birth ; sometimes not evacuated for several hours after birth. Characteristics of Full Development.—Ability to cry ; moves limbs readily ; body clear red ; mouth, eyelids, nostrils, and ears open ; cranial bones firm, and edges of fontanelles not far apart; hair, eye-brows, and nails developed ; discharge of meconium within a few hours after birth ; capability of sucking. Of Immaturity.—Small in size ; motions feeble ; inability to suck; skin intense red, with blue streaks; head covered with down; bones soft; fontanelles wide; nails not formed; eye- lids, nostrils, and mouth closed ; stools and urination imperfect. Vernix Caseosa ; or Smegma : An unctuous yellowish white substance that covers foetus more or less completely; in some almost absent; most about head, axillae, and groins. Is the effete epidermis, with the secretion of sebaceous glands. Is insoluble in water, alcohol, and oil, partially in potash. Position of child in utero : Formerly supposed to be sitting, and that it revolved—not so. It is usually unaltered through- out gestation ; the arms are folded on chest, knees drawn up, feet crossed, back curved, head bent forwards.

But the determinate position is not as- sumed till about the sixth month, perhaps not till later. DIMENSIONS OF FCETUS AT TERM—Length, 18, 22, 24 inches. Weight, average 7 lbs. Diameters of Fcetal Head.—Longitudinal or Antero- posterior, from forehead to occiput, 4—4^ inches ; Transverse or Bi-Parietal, between parietal bosses, 3{—4 ; Occipito-Mental or Oblique, from posterior fontanelle to chin, 5 ; Cervico-Breg- matic, perpendicularly from highest part of sagittal suture, 4— 4£; Occipito-Bregmatic, from anterior fontanelle to midway between occipital protuberance and foramen magnum, 3$; Inter-Auricular, 3; Fronto-Mental or Facial, from frontal boss to point of chin, 3—3^. Circumferences of Head.— Occipito-Frontal; Occipito- Mental, the largest; Sub-Occipito-Bregmatic, runs through extremities of bi-parietal and occipito-bregmatic diameters. This and the preceding are the important ones. Facial or Fronto- Mental. The diameters are not invariable. The head in difficult labors elongates in course of occipito-mental diameter, and flat- tens transversely. By instruments, the bi-parietal may be re- duced one-third of an inch.

MANUAL OF OBSTETRICS. 99 By comparing these diameters, it will be seen that, in order for the head to pass, it must present either the occipital or mental end of the long diameter. Besides the diameters, the foetal skull possesses points of in- terest in the fontanelles and sutures. Anterior or Greater Fontanelle or Bregma.—Formed at the junction of the sagittal, coronal, and frontal sutures ; is quadrilateral with four angles, or lozenge-shaped; sometimes prolonged down the frontal bone. Posterior or Occipital Fontanelle.—Smaller than pre- ceding ; formed by union, of the two limbs of the lambdoidal suture with the sagittal; is triangular with three angles; in rare cases has four, from non-union of occipital bone; recog- nise it by the acute angle of the lambdoidal suture. The Sutures, of interest, are sagittal, frontal, and lambdoi- dal, because they indicate the position of the head. Advantages of Sutures, &c.: To allow edges to ride over during labor; again it is thought that compression of fcetal head causes insensibilityand prevents struggles. The heads of boys are larger than those of girls, J?th or J„th; hence more males are still-born than females, 14 to 10. Labors with males are severer. More males than females are born, 106—100. A country life seems to favor the production of males. The relative age of the parents exerts an influence. Upon a mean number of births, the sex of the child is that of the parent whose age is in excess. By Emerson in Philad., it was found that the maximum of conceptions occurred in winter and spring, especially the latter; the smallest number in summer and autumn, the minimum in summer. Abundance of food seems to favor male conceptions. Scarcity, female. The occurrence of epidemics induces female births. Sources of Foetal Nutrition.—At first by imbibition through villi of chorion. The umbilical vesicle is thought' to contribute. Liquor amnii most probable source. It is absorbed 100 manual of obstetrics. by cutaneous surface, for a foetus has been found without pla- centa, funis, mouth, or anus. It is also swallowed, for hairs have been found in it and epithelium. The meconium is thought to be the result of digestion. Calves have been nourished for two weeks upon it. (How is nutrition effected in cases where liq. amnii is evacuated weeks before delivery ?) The placenta is rather an organ of hematosis than of nutrition. Other sources are said to be milky juice of utricular glands, gelatine of cord, allantois. Fcetal Circulation.—The peculiarities are the ductus venosus, foramen ovale, ductus arteriosus, umbilical arteries, umbilical vein. Ductus Venosus.—Communicates between umbilical vein and inferior cava. Just at the point where the two fissures of the liver intersect, the umbilical vein divides; the posterior branch, called the ductus venosus, goes sometimes to the vena cava, sometimes, though rarely, to one of the hepatic veins, and then empties into the cava ; the other branch unites with the vena porta, and ramifies through the liver, subsequently going to the cava. Foramen Ovale.—Foramen of Botal: Exists in the inter- auricular septum. Ductus Arteriosus.—Communicates between pulmonary artery and aorta, entering aorta on its transverse arch. Umbilical Arteries.—Two in number. Branches of inter- nal iliac or hypogastric arteries ; pass to sides of bladder, ascend through the umbilicus and along the cord. Course of Blood.—Satatier's, or figure of eight theory.— Blood enters by umbilical vein; part goes to vena cava through ductus venosus, part to liver and through portal circulation, thence through hepatic veins to cava, thence into right auricle, thence through foramen ovale into left auricle, thence into left ventricle, thence through aorta and its various branches, &c.; the major part returning by the umbilical arteries. The blood of the superior cava returns into right auricle, thence to right ventricle, thence to pulmonary artery, a little to the lungs, the MANUAL OF OBSTETRICS. 101 main stream through ductus arteriosus, where all the blood commingles. Winslow's theory.—The blood passes into right auricle as in adult; thence a part through the right ventricle; pulmonary artery, and ductus arteriosus, into the aorta; another and larger part through foramen ovale into left auricle, thence to left ventricle, thence through aorta and its branches. The foetal pulse is not synchronous with maternal; it beats 120 to 150. State of lungs before birth.—Small, unaerated, dense and firm, small branches pass from pulmonary artery for their nutrition ; function not yet required. Immediately upon respiration, the current of blood is di- verted to the lungs, the ductus arteriosus is useless, the foramen ovale is closed by the valve developed for that purpose, and the usual mode of circulation obtains. The umbilical arteries close on the 2nd day, and in three weeks are coaverted into a cord. The umbilical vein and ductus venosus are contracted on the 4th day, and closed on the 7th. The ductus arteriosus andforamen ovale rarely persist beyond eight or nine days, but sometimes the foramen ovale is persis- tent through life; sometimes causes one form.of the morbid state known as morbus coeruleus. The ductus arteriosus and umbilical arteries become oblite- rated by hypertrophy of the walls; the ductus venosus and umbilical vein simply because no blood traverses them. Pathology of Foetus.—May be affected with numerous diseases in utero; either coincidently, or independently of mother. Instances known of Intermittent Fever, Variola, Rubeola, various cutaneous eruptions, Hydrocephalus, Pleurisy, Abscesses, OZdema, Tubercle, Peritonitis, Enteritis, Hyper- trophy, Atrophy, Syphilis, Worms, Rickets, Caries, Necrosis, Pertussis. Death of Foetus.—A knowledge of it is frequently of importance, especially in reference to obstetric operations. 102. MANUAL OF OBSTETRICS. It is difficult to ascertain the fact. Signs.—1. Cessation of motion. 2. Subsidence and flaccidity of abdomen. 3. Recession of umbilicus. 4. Loose feel of uterine tumor. 5. Sensations of rolling in abdomen, also weight and coldness. 6. Breasts becoming flaccid and milk suppressed. 7. Health deteriorated. 8. Appetite bad. 9. Countenance sunk, areola around eyes. 10. Fetid breath. 11. Rigors. 12. Loss of auscultatory phenomena. Separately these signs are not reliable; a number conjoined makes death probable. Fallacies.—Motion is frequently suspended without cause; woman's account not to be trusted. Sense of coldness no value. Sense of rolling may occur and yet foetus alive; may proceed from loss of tone of abdominal muscles. General health deteriorated by other causes. Breasts seldom become flaccid after being tense without death. A dead foetus may be retained for months without these signs; or may be retained and motion fancied. Auscultation may not give information, for practical tact may be deficient, or sound inaudible. After rupture of membrane, liq. amnii may be dark, thick, bloody, or even fetid, and child alive. More certain signs are —1. Emphysematous feel of scalp. 2. Peeling of cuticle. 3. Loose overlapping of bones. 4. A peculiar sharpness of edges of bones. In face presentations, lips flabby, tongue flaccid and motion- less. In breech, sphincter ani readily admits finger; discharge of meconium in no presentation a sign of death. In arm presentation pulse may cease, arm be discolored, and yet alive; but if cuticle peel, child is dead. In funis presentations, absence of pulsation not always a sign of death. Superfoetation.—Def. A second impregnation while the uterus contains an embryo or foetus. Much doubt as to its possibility. MANUAL OF OBSTETRICS. 103 Cases giving rise to this opinion are—1. A full grown foetus and a blighted ovum delivered together. 2. A twin birth, one fully developed, the other immature. 3. Twins of different colors. 4. Cases in which a mature child is born and some months after it a second mature child ; instances of 4J months interval, 3 months. First and second classes prove nothing, only a blighting of one ovum in a twin conception, or else a difference of develop- ment ; in such cases the living child is usually vigorous. Third class requires a speedy succession of coitions. Fourth class— one case explained by existence of double uterus. Obstacles to second impregnation are decidua, plug of mucus in cervix uteri. Extra Uterine Pregnancy.—Three forms said to exist. Ovarian, Tubal, and Interstitial; some recognise a fourth, Ventral. Ovarian ; doubted by some. Tubal most common form, for impregnation occurs in the tube. Interstitial very rare. Causes conjectural only. Symptoms.—Sometimes resemble disease of uterus or ovaries. Usually much suffering from an early period. Not easily made out before 3d month. Certain signs of pregnancy may be present, but irregular ; thus, menstruation may be regular or suppressed, absent, profuse; the mammary changes occur; nausea may occur; foetal motion early perceived; abdomen increases on one side and pain localized in the tumor; sense of weight and uneasiness in kidneys and pelvis ; per vaginam os is high or depressed, but not dilated; cervix undeveloped; a constant circumscribed pain in groin. When cyst ruptures (which is ordinary termination) great uneasiness or pain suddenly occurs, languor, debility, extreme exhaustion, sometimes bloody discharge from vagina, dysuria, tenesmus, irritable stomach, collapse from loss of blood. 104 MANUAL OF OBSTETRICS. These symptoms more sudden in tubal; interstitial also rapidly; the crisis accelerated by violent motions, shocks, blows, coughing, vomiting. Termination.—Commonly terminates before fifth month; sudden by shock, hemorrhage, inflammation; or survive and recover a measure of health ; may even conceive again, instances one to seven times. Foetus may be retained from. 3 months to 56 years. Mont- gomery, an instance, woman lived till 94, had foetus in abdo- men for 46 years, and during this time bore two children. A pseudo-bony cyst may form ; abscess may form and foetus be evacuated piecemeal through abdominal integuments, groin, umbilicus, epigastrium, colon, rectum, vagina, or bladder, in which last sometime^ fragments have formed the nucleus of a calculus. Foetus may live till 9 months, rarely, however, beyond 3rd or 4th. The development proceeds as usual, and even a quasi decidua is formed. At term a pseudo labor may occur. Treatment.—First indication is to retard rupture of cyst; avoid exertion, uterine irritation and pressure; if uneasiness occurs, VS. leeches, and opium. If rupture occur, the indication will be to moderate effusion and to support strength. Hard bed, head low, binder to abdomen, ice, acet. plumb., broths, stimulants. If inflammation set in, use opium as for peritonitis, VS., cal. et opium, blisters.* After rupture, foetus dies ; keep quiet, bowels open, leeches and anodynes for renewed pain. If abscess forms, caution is requisite in opening, lest hemor- rhage ensue. Gastrotomy has saved a few cases. Abortion.—Def. Expulsion of the embryo before it is ' viable. Foetus is viable at 7 months or 64- months. Every foetus that moves at birth is not viable—instances of children reared, born at beginning of 6th month, at 6 months and 10 days. MANUAL OF OBSTETRICS. 105 A case by Dr. Barrows of Hartford in Amer. Jour, of Med. Sciences for April, 1853, gives an example of a female child, born before the completion of the fifth month, 10 inches long, weight 14 ounces; evinced respiration, pulse, voluntary motion, and utterance of sound for forty-five minutes. The particulars are given with minute fidelity. Premature delivery is applied to expulsion after viability. Miscarriage is the popular term for all immature expulsion. Danger, popularly lightly esteemed. Ingleby records 4 fatal cases from hemorrhage, Denman 2, Whitehead 3. Frequency, 1 in 78£; is the most frequent form in which hemorrhage presents. Few women pass through menstrual life without aborting, 8 only in 64. Thought that first preg- nancies most liable; doubtful, if the cases produced designedly are thrown out of consideration. Male conceptions supposed most liable, but it is difficult to determine sex. Divisions.—Spontaneous, arising without obvious cause. Accidental, produced by injury, &c. Designed. Class of Society.—Most frequent in extremes. Kind of Women.—Plethoric, nervous and irritable, indolent, dissipated. Constitutionally diseased, ex. gr. syphilis. Organic uterine disease. Polypus; tumors, especially of os. Ad- hesions ; displacements; acute diseases, as variola, scarlatina, rubeola, typhus. Occurs at.—About third month most common, coincidently with menstrual period ; many women can recognise the cata- menial period by an imperfect nisus for first three months, some throughout gestation. Reason, irritation of ovarian nerves causes a nisus, afflux of blood, separation of recently formed placenta, hemorrhage, and abortion. Causes, Predisposing and Exciting ; or better, Ovuline —Uterine—Constitutional—Accidental. Ovuline, very common. Still-born in Europe 1 in 22 births —of 935 cases analysed, 71 occurred or 12| per cent, nearly. Hydrocephalus; pleuritis ; peritonitis; variola even without affecting mother. Syphilis; Convulsions and Intermittent 9 106 manual of obstetrics. said to occur in utero ; plurality of ova; placentitis ; placen- tary congestion; fatty placenta; rupture of umbilical vein— diseases of chorion, of cord. Easy to understand why death of foetus gives rise to expul- sion, a foreign body excites contraction. But considerable time may elapse between death and expulsion. Uterine Causes.—One said to be irritability of uterine fibre (a phrase to conceal ignorance). Retroversion ; ante- version ; adhesions; fibrous tumors; polypus; cancer; cauliflower excrescence ; corroding ulcer ; placenta praevia ; ulcerations of cervix in various forms; endo-uteritis; dys- menorrhcea. Constitutional Causes.—Syphilis—Tuberculous disease (phthisical women are peculiarly susceptible of impregnation), variola and other acute diseases. Uraemia said to be ; miasmatic residence; Scorbutic diathesis. Tight-lacing ; and analogously, abdominal tumors. Irritation of dens sapientiae and extrac- tion ; protracted lactation; women advanced in life with first pregnancy said often to be the subjects of abortion. Cystitis; diarrhoea; dysentery ; ascarides ; constipation ; piles ; stran- gury. Mechanical Causes.—Coitus ; plugging vagina for hemor- rhage ; puncturing membranes ; violent exercise, as horseback, jolting over rough roads ; carrying heavy weights ; blows; falls; sudden efforts ; vomiting ; dancing. The strong compression in convulsions, hysteria, or epilepsy ; operations. Certain Medicines.—Emetics ; emmenagogues, savine, ergot, tansy; mercury ; bleeding; opium. Emotional Causes.—Terror, Putrescent discharge; 6th, Flatus from uterus ; 7th, Want of cerebral pulsation ; 8th, Loss of funic pulsation ; 9tb, Desqua- mation of cuticle; 10th, Looseness of bones; 11th, Emphysema; 12th, Loss of stethoscopic signs.) (If you anticipate that perfo- ration will become necessary, watch the fcetal heart closely.) 2nd. Antero-posterior diameter less than three inches. 3rd. Bis-ischiatic less than three inches. 4th. Fibrous and other tumors. 5th. Hydrocephalus. 6th. Convulsions, rupture, and hemorrhages. 1th. Hand with head in too narrow a pelvis. 8th. In breech cases. 9th. Head left in utero. MANUAL OF OBSTETRICS. 233 Period: 1st. If pelvis is very much distorted, operate as soon as os is dilatable. 2nd. If there is doubt of capacity, wait awhile; also in tumors, &c, wait. 3rd. In convulsions and such like emergencies, circumstances must regulate. Every one who employs the perforator, should remember that he designs to kill a human being ; whether that murder be justifiable or otherwise, must be answered by each one's own conscience. Mode of Operating.—Preliminaries: Os to be dilatable ; bladder and rectum to be emptied. Position as for forceps. Dress to be arranged; also cloths, &c, to receive brain. In- struments to be warmed. Consultation. Chloroform. Intro- duce two fingers, and upon them the scissors ; avoid a suture or fontanelle ; rotate steadily, but with moderate pressure, until the bone is perforated ; be sure you are through the caput suc- cedaneum; push scissors up the shoulder; make an assistant separate them ; make another opening at right angles, and then twist the scissors around so as to make a large hole ; push the instrument thoroughly through all the brain; withdraw, and with the finger make sure of the medulla oblongata; wait ten minutes for the brain to exude; pass in the crotchet, and fix it to either the base or facial bones; fold the scalp over to pro- tect ; guard the point of the crotchet with the other hand, and pull 'with both, so that if a slip occurs both hands slip together; pull during a pain ; "remember the axis of the pelvis ; take care of spicule. Some prefer craniotomy forceps, which should be introduced one mandible into the skull, the other outside, and fully up to the face. If great difficulty is experienced, a delay of some hours will weaken the structures, allow of moulding, and facilitate extrac- Dangers : The perforator may merely penetrate the infiltrated scalp, and slip on the skull. The crotchet may slip, and wound vagina. The shock is great from the condition of the patient; is diminished by chloroform. Inflammation not unfrequent subsequently. The child has been born living. 234 MANUAL OF OBSTETRICS. After Treatment: A full dose of morphine; and, if threat- ening symptoms arise, Narcotism. The Cephalotribe is a pair of long and very strong forceps, which close much more than the ordinary instrument. The blades, which are very thick and strong, are introduced sepa- rately, and then approximated by a screw, thus crushing the head. Symphyseotomy, the Sigaultean Operation.—Devised by Sigault,in 1768 ; was highly lauded, but is now abandoned. Statistics : 49 cases, 16 mothers died. An analysis of the cases shows that 16 mothers were sacrificed to save 5 children. Cesarean Section, Gastro-hysterotomy.—An operation to extract the fcetus from the uterus of the mother through the abdominal parietes. Was known to the ancients as a means of saving the child after the death of the mother. Scipio Africanus, Claudius Caesar, Julius Caesar, are said to have been so born. First performed successfully on a living woman about 1500, by a cattle-gelder on his own wife. In several cases it has been repeated on the same patient. Rousset mentions a case operated oh 6 times. Objects.—1st. To afford to mother a relief from destruction, to the child a chance for life, when even the dead foetus cannot pass per vias naturales ; antero-post. diameter under 1^ inches by 3 in transverse. 2nd. To extract a child after sudden death of the mother; eyen as late as an hour after death. 3rd. To extract foetus after extra-uterine pregnancy, or ruptured uterus. Is rather gastrotomy. Statistics.—Are not reliable from the suppression of un- favorable cases, while successful are probably all reported. British and American practice 52 cases, 14 mothers saved, 4 lost. In 49 cases, 28 children saved—1 in 2£. MANUAL OF OBSTETRICS. 235 Foreign: 382 cases, 223 mothers saved—1 in 2£. In 200 cases, 147 children saved—57 lost. Total results: 434 cases, 237 mothers saved—197 lost. 249 cases, 175 children saved—74 lost. Period.—Early, if there be no doubt of- necessity. The duration of labor over 72 hours is unfavorable to both mother and child. The greater the time after rupture of membranes, the more hazard. Mode of Operating.—Preliminaries.—Evacuate bowels and bladder; ascertain position of placenta; apartment heated to 80°. Chloroform. Incision from 6 to 10 inches along linea alba or by the side of rectus, or horizontal.above pubes; through integument and peritoneum; not so long in the uterus; draw out liq. amnii by syringe or sponge, then enlarge the incision; remove child quickly, and membranes by twisting, especially from near os, and be sure that os is pervious for the lochia; (uterine contraction detaches the placenta); uterine wound of 5 or 6 inches will contract to 2 and requires no suture ; the abdominal parietes are to be kept close to the intestines. Dressing by twisted, or by quilled suture, and long straps ; water dressings; lower angle to be free. After Treatment.—Opium. Dangers.—Shock; hemorrhage; strangulation of intestines; metritis and especially peritonitis. Vaginal Hysterotomy.—Incisions into the uterus per vaginam. Has been practised in cases where closure of the os has occurred after impregnation, as the result of inflammation, either from disease, or as a sequel of attempts** abortion Incisions to be made, so as to avoid bladder in front, and rectum posteriorly. Chloroform. Has been objected to as "immoral," as "indecent," 236 MANUAL OF OBSTETRICS. " annulling only a physiological phenomenon," but more espe- cially as being hazardous to life. Of these, the last only deserves consideration. Its hazard in careless hands is freely admitted; fatal results have followed, and doubtless will follow, the use of chloroform, even in midwifery, though as yet no such event has occurred in its obstetrical employment. But are there not concomitants and consequences of labor, as peri- lous to life immediately, as deleterious to enjoyment of life subsequently, often seen in labors distressing by severity at the time, and entailing sufferings, which a lifetime does not suffice to remove ? The nervous shock attending labor is frequently of great severity, its effects often very persistent; and from this shock what agent yet discovered offers the immunity given by anaesthetics? In all cases demanding operations, the use of chloroform is the obstetrician's most valuable adjuvant, and especially does it disarm version in severe cases of its terrors ; and to nothing does irregular or hour-glass contraction yield so ready an entrance. Forceps and embryotomy operations are equally facilitated. The employ- ment of anaesthetics in operative midwifery meets with but limited opposition, but more objections are urged against their use in regular labor; even here, however, there are many cases where relief can be given, and should not be withheld. 1st. Severely felt but short and ineffectual pains which restrain voluntary and bearing down efforts—here chloroform acts as a* co-ordinator of forces, blunts abnormal sensibility, renders contractions longer, steadier, and more efficacious, and sometimes remarkably accelerates labor. 2nd. In muscular women of rigid fibre the dilating of the soft parts is often extremely painful. 3rd. Delicate and nervous women, worn out by not exces- sively long labor, are relieved by the rest obtained by chloro- form. 4th. Of its use in convulsions (see page 172). Not, however, in all cases, ex. gr.: If strong objections are offered, anaesthetics should not be MANUAL OF OBSTETRICS. 231 forced, and even if moderate aversion, exists it should be respected. Time of Giving.—Ordinarily not till 2nd stage; if pains are very severe, this may be anticipated. Mode of Giving.—A handkerchief or towel, sprinkled with about half a drachm of chloroform, is to be held near, but not upon the mouth, and the patient encouraged to take long and deep inspirations; atmospheric air is to be admitted; deep snoring anaesthesia must not be reached, but a bare sufficiency to mitigate suffering. While this is in progress the patient may be quite sensible. In the intermission of pains the towel is removed, and reapplied as the pain approaches. Cautions.—One hand is to watch the pulse constantly. ^ Allow plenty of atmospheric air. Temperature not to be high. At no time overwhelm the patient; do not commence with a full dose. Keep inside of anaesthesia. Administration soon after a meal is objectionable, or after a long fast. ORDINARY MANAGEMENT OF CHILD. As soon as cord is divided (for time of which see Manage- ment of third stage of labor, page 128), place one hand under head, and grasp the shoulder with the thumb; with the other hand grasp the thigh furthest from the operator, so as com- pletely and securely to hold the infant, and then place it ma blanket, or some flannel provided for the purpose, and confide to the nurse. . , _ . Washing the CniLD.-Should be in warm water, and not in the lying-in chamber. If much vernix caseosa is upon it, lard or sweet oil is to be freely smeared over it and then with a flannel cloth and soap the child is cleansed thoroughly; the eyes are to be washed with warm water without soap; cleanli- ness Tnot so essential as to risk the integrity of the skin- nimia diligmtia nutricis. 238 MANUAL OF OBSTETRICS. Dressing the Cord.—When the child is fully dried, take a piece of old linen about seven inches square, cut a hole in the middle, through which pass the cord, and envelope with th^ linen; then place upwards along the abdomen and have a flannel roller applied loosely around to secure the cord. Avoid the filthy burnt rag usually suggested by the attendants. The cord usually falls off by the fifth day. To facilitate its removal apply a bread and water poultice over night. I have seen the cord still attached on the fifteenth day. Child's Dress.—Essentials are, warmth, looseness, and with- out pins; tapes being preferable. Caps are to be avoided. Long sleeves ought to be worn, but fashion is omnipotent against health. Dress should cover chest, and be high on the neck. The diapers or " squares " should be soft, and of old preferable to new stuff; excoriation sometimes ensues from stiffness. Medicine.—A teaspoonful of cold water : the colostrum. The practitioner's voice should always be raised against the various compounds of butter and sugar, molasses, &c, that are usually given. If the bowels are not freely opened by the second day (provided imperforate anus is not the cause), a small teaspoonful of castor oil is sufficient. Food.—None equal to the. natural supply. Always have child nursed within two hours after birth, provided great exhaustion, as by hemorrhage, &c, has not occurred. Assur- ances of " no milk in the breasts," are frequently falsified by the child's swallowing immediately. The best substitute is one third of cow's milk and two thirds of water sweetened with loaf sugar. Until teeth appear, milk should constitute the infant's food. Child should be taught early not to nurse at night. Inter- vals of two or three hours, according to the nutritive properties of the milk, will suffice during the day. Experience soon teaches the injuriousness of " night-nursing." Sleep.—Not in a cradle. Not by mother if practicable. But children of feeble vitality require the heat .of mother's MANUAL OF OBSTETRICS. 239 body. It should always be borne in mind that the new-born child has much less capacity to resist the influence of cold than the adult. An apartment comfortable to an adult is often far too cool for child's comfort and well being. MORBID STATES OF THE CHILD AFTER BIRTH. 1st. In a state of ANEMIA, SYNCOPE, or ASPHYXIA. . Caused by, too early detachment of placenta; uterine hemorrhage; defective nutrition. Symptoms.—Very feeble if any respiratory efforts ; no pulsa- tion of cord ; fcetal heart weak. Treatment.—Tie and divide cord; warm bath; cold affusion; friction with brandy and flannel; titillating nose and fauces with feather; electricity ; artificial respiration. 2nd. ASPHYXIA.—Caused by prolonged labor; abnormal presentation ; &c. Symptoms.—Weak pulsations of funis; color natural. Treatment.—Wait before dividing cord; frictions; cold dash ; alternate warm and cold bath ; inflation ; these failing, divide cord and bleed Jss. 3rd. APOPLEXY.—Caused by prolonged labor; narrow pelvis ; delay to passage of shoulders. Symptoms.—Pulsation of cord feeble and oppressed; surface and face livid. Treatment.—Divide cord; bleed Sss.; baths; friction; inflation. INDEX.

M This is an exceedingly clever little work—clear, concise, and to the ft purpose. We know of no work on the subject better adapted to the wants of the student who is just beginning the study of Auscultation."—Medical Examiner. " We are fully convinced that this work is well adapted to the wants of students, and that it supplies an obvious deficiency in the medical literature of our country. Plain and simple in its arrangement, accurate in detailp, and sufficiently extensive for elementary purposes, it should become the companion of every student of auseultation."—Western Lancet. " It is an excellent elementary treatise, clear, precise, and accurate, and may, as such, be strongly recommended to the student."—Amer. Jour, of Medical Sciences. " This is a concise, yet clear and comprehensive—compact, yet sufficient Biimrnary of the essentials of Auscultation, by an accomplished Stethosco- pist."—-Annalist. " Dr. Bowditch has the honor and credit of having given to the profession one of the most concise, clear and comprehensive works on physical diag- nosis, hitherto published in any country."—New York Jour, of Medicine. " This is a practical work on Auscultation, and well calculated to interest and instruct all who have a love for the science of physical diagnosis."— Missouri Med. and Surg. Jour.

" If every young practitioner were to carry this little volume about him aa a pocktt-book, for which its size so well adapts it, and read it during his houra of attendance on tedious cases of labor, we should 3ee and hear less of mal- practice than some of us, alas ! are compelled to witness."—Med.
