1 8 97. DANIEL DENISON SLADE. 
" Altissima quieque flumina minimo sono labuntur."-Quintus Curtius Rufus. 
Daniel Denison Slade, the subject of this sketch, was born on 
Beacon Hill, near the State House, Boston, May 10, 1823, and 
died at Chestnut Hill, near Boston, February 11, 1896. His father 
was Jacob Tilton Slade, a Boston merchant, and son of Benjamin and 
Susanna (Tilton) Slade, of Portsmouth. Mr. J. T. Slade was born 
in Portsmouth in 1778, and for many years was engaged in business 
in St. Petersburg, Russia. In 1827 he left Boston for the continent, 
where he lived until his death in June, 1854. He was a man of 
captivating personal appearance, tall, and posessing fine physique 
and a robust constitution. His wife, Elizabeth (Rogers) Slade, 
was a daughter of Daniel Denison and Elizabeth (Bromfield) 
Rogers, and granddaughter of Col. Henry Bromfield, of Harvard, 
Mass. Mrs. Slade died in 1826, in the home erected for her adjoin- 
ing the so-called mansion-house of her father, Daniel Denison 
Rogers ; whereupon her brother, the late Henry Bromfield Rogers, 
became Daniel's guardian. To him, a man of excellent judgment 
and liberal religious faith, Daniel Slade was indebted for many of 
his sterling qualities of character. Daniel D. Rogers was a suc- 
cessful Boston merchant, residing in a large brick mansion which 
he built on the lot of land between Mt. Vernon and Bowdoin 
streets, and facing Beacon street. In this house Daniel lived until 
he was ten years old, in care of his grandmother and his aunt 
Hannah, who afterwards became Mrs. William Powell Mason, and 
the place never ceased to possess attractions for him. 
As the records are very complete and readily accessible,* it will be 
sufficient here to indicate tbe genealogy only in a general way. Beginning 
with Rev. John Rogers, who emigrated from England in 1636, and later 
became the fifth president of Harvard College, the male line of descent is

A genealogy of the Richard Clarke family is reported to be in preparation by Isaac J. 
Greenwood, A.M., and will be published shortly in the Register. Some notes regarding 
this family will be found in Dr. Slade's article in the Register, vol. xlvi., pp. 15-16,

as follows: John1 (b. 1630, d. July 2, 1684), m. Elizabeth Denison, 
daughter of Major-General Daniel Denison and wife Patience Dudley, who 
was the daughter of Governor Thomas Dudley; Rev. John3 (b. July 7, 
1666, d. Dec. 28, 1745), m. Martha Whittingham, daughter of William 
Whittingham and grand-daughter of John Lawrence of Ipswich; Rev. 
Daniel8 (b. July 28, 1707, d. 1785), m. Anna Foxcroft, daughter of Thomas 
and grand-daughter of Francis Foxcroft, of Cambridge; Daniel Denison4 
(b. May 11, 1751, d. March 25, 1825), m. Elizabeth Bromfield, who was 
the only child of Henry Bromfield, of Harvard, Mass., by his second wife 
Hannah Clarke; Elizabeth Rogers6 (b. Sept. 11, 1798, d. Aug. 14, 1826), 
m. J. T. Slade. 
Hannah Clarke was the eldest daughter of Richard (b. May 11, 1711, 
d. 1790) and Elizabeth (Winslow) Clarke, of Boston. Another daughter, 
Susanna, married John Singleton Copley, the artist, their house being on 
Beacon street, on the site of the present Somerset Club House. Henry 
Bromfield (b. Nov. 12, 1727, d. Feb. 3, 1820) was the second son of Ed- 
ward (b. Nov. 5, 1695, d. April 10, 1756) and Abigail (Coney) Brom- 
field. Edward's father was the first of the name to emigrate to this coun- 
try, the family being traceable in England as far back as the reign of Edward 
II., and being undoubtedly of Welsh origin. It appears that the grand- 
mother of Edward Bromfield, who came to America in 1675, was one of 
the Quincy family. Thus, not only was Daniel Denison Slade the bearer 
of an illustrious New England name, but in him converged the lineage of 
a number of highly distinguished families. 
Having early manifested an aptitude for study, great pains were 
taken in providing the young Daniel with proper educational advan- 
tages. Accordingly, we find him transferred at the age of ten years 
from the public school system of Boston to the care of the Hon. 
Stephen Weld, of Jamaica Plain. Afterwards he was removed to 
the family school of Rev. Ezra Ripley, of Waltham, and in 1835 
he was sent to Northborough, where he lived two years in the 
charge of the Rev. Joseph Allen. Of his life there, and his at- 
tachment to the school, we have abundant record.* The following 
extract from a letter dated Oct. 1, 1835, is significant, since it fore- 
shadows his devotion to natural history, the pursuit of which after- 
wards became one of his ruling passions : 
"Northboro' is a very pleasant little place. The leaves are just begin- 
ning to turn red and white and yellow, and the woods look very pretty 
indeedThe boys have got a society up among themselves to collect 
specimens of stones, and curious things that we might happen to find. I 
was chosen Secretary, but declined the office. We have a meeting every 
Monday evening." 
His first literary efforts were embodied in a series of contributions 
to an amateur paper called The Meteor, published by Dr. Allen's 
pupils at Northborough in 1836. 
The following additional extracts from early letters will serve to 
indicate his remarkable love for rural life and for historical associa- 
*See also "Twelve Days in the Saddle," by " Medicos," [D. D. S.], p. 32. 5 
tions. The homestead referred to in his first quotation was the 
birth-place of his grandmother, Mrs. D. D. Rogers, situated in 
Harvard, Mass. 
"The Bromfield mansion at Harvard I have not visited since last fall. 
It is a grand old place, and my attachment for it was always great. Many 
of my happiest associations are connected with it ... . How many 
times have the old walls rung with laughter from lips now silent in the 
dust .... Would that everything had been preserved as it original- 
ly was; all the old furniture, pictures, prints, etc. The old trees still live, 
but Time has laid his withering hand upon some of them." 
"I look forward with the greatest pleasure imaginable to the time when 
I shall be sole possessor of a snug little farm and cottage. You know the 
taste which I have. 1 attribute my love for the country and for agricultural 
affairs to the early age which I passed so pleasantly at Harvard with you 
[Rev. Mr. Blanchard]. Some of my happiest associations are connected 
with that period. It is my earnest hope that nothing will ever occur to 
diminish my love for rural life." 
Mr. Slade was finally prepared for college at the Boston Latin 
School, where he acquitted himself very creditably. Il was a life- 
long habit of his to preserve with the greatest care and system all 
manner of documents, letters and personal souvenirs; and he had 
also the laudable virtue of keeping a journal and a scrap-book. 
Some years before his death Dr. Slade took occasion to look over 
an old file of " Monthly Reports " of the Latin School, signed by 
the venerable master, E. S. Dixwell, and countersigned by II. B. 
Rogers. To this file he added the following; memorandum: "At 
the Latin School I was obliged to contend with boys who had en- 
joyed the great advantages of this school for several years, while I 
had received little or no solid instruction. It was in every way a 
severe test of ability." The reports are of uniform excellence ; and 
at this school, also, a silver medal was awarded him in 1840 for 
Latin hexameter verses. 
Mr. Slade entered Harvard when seventeen years of age, passing 
the entrance examinations with distinction. The four years of his 
undergraduate experience proved to be a great formative period in 
his career. During it, his abilities as a student were abundantly 
manifested, as is witnessed by the fact of his receiving a detur 
(Bacon's Essays) and several honorary prizes, one of these being for 
the best Latin poem. During this period, also, were nurtured and 
strengthened those tastes which remained most dominant in him 
throughout life, especially his fondness for literary, historical and 
scientific pursuits. Of the Harvard Natural History Society he 
was successively vice-president and treasurer, president, and curator 
of ornithology and geology; and he contributed to it his enthu- 
siastic support. The friendships, too, that were formed during his 
college days proved to be the closest and truest of his whole life. 
A classmate of such men as Francis Parkman, Leverett Sal tonstall, 6 
George S. Hale, T. E. Francis, Robert Codman, George M. Brooks 
and B. A. Gould, the mutual attachments initiated during their 
college course grew warmer and firmer with increasing years, so 
that it is impossible to disassociate his memory from connection 
with these intimate friends. 
Life at Harvard during the forties is depicted very graphically 
and in a remarkably ingenuous style by Mr. Slade in his journal, 
some extracts from which have been incorporated in the semi-cen- 
tennial Class Report recently prepared by Mr. Edward Wheel- 
wright. In this journal we read of customs and associations that 
have long since passed away; we see strange faces and hear unfa- 
miliar voices. We attend Exhibition Day, "pass a pleasant hour " 
with the president, parade with the Navy Club, dance around bon- 
fires in the yard, and celebrate Class Day and Commencement in 
the good old style. Even the student vernacular is out of date 
nowadays ; there is no longer bathing in the Charles nor boating on 
Fresh Pond ; neither do we pay toll on the mill-dam, nor " 12 J cents 
for an omnibus ride to any part of the city." And the chapel bell 
no longer rings for morning prayers at "some hour during the 
night." We may be permitted a peep at this bygone era through 
the loophole of the following passages; and should any of them 
appear trite, it must not be forgotten that the college was then 
hardly more than an Academy, and that the diarist was a lad under 
twenty: 
1842. Mar. 1. Made a decent recitation in Latin. I resolved that I 
would not use a pony this term, but seeing some nice little ones for Greek 
at the store, and learning that most of our class had them, I could not re- 
sist the temptation and bought one. 
Apr. 13. Had the proctor up in my room yesterday the second time for 
playing upon my flute. I wish he would stop a little of the noise that is 
sometimes made in the entry instead of attacking me and my flute every time. 
May 2. Our [Oxford] caps came out from Boston. Snow, Perry, and 
myself christened ours in Treadwell's room with whiskey punch, lemonade 
etc. We made a great noise. 
May 18. As the West Cambridge omnibus went by this morning there 
was a man upon the top of it with a caricature of the " Cap " upon his 
head. Some of the students being near stoned him, and not only knocked 
the cap from his head but also broke several of the omnibus windows. 
We expected him again at night when the omnibus came along, and we 
were not disappointed. There he sat with that cap on, and with a most 
triumphant look, but he was not doomed to stay there long. As the omnibus 
came along, White - Junior - ran out and threw a water pail so fairly 
as to strike him directly under the rim and thus knock it off; volleys of 
stones immediately followed, and several chased the omnibus nearly to 
Mrs. Schutte's where it stopped, as I understood, to let a lady out. Rowan 
-Freshman-climbed up upon the omnibus and took the cap away, while 
two or three more getting up behind struck him and knocked him off. He 
fell upon his back, but nobody interfering with him, he got up and ran for 
his life, having a dozen at his back, striking him with their canes. The 
fellow would have been all but killed had not a gentleman taken him into 7 
his chaise. He promised he never would wear it again. We gave three 
cheers, and marched back with the cap as a trophy to the college yard. 
May 19. The omnibus from W. Cambridge went by this morning very 
peaceably, no hostilities being shown. The man who wore the cap was 
hired by some one who was an enemy to the college, hoping to get up a 
disturbance. The President gave us a very fine speech this morning in 
which he appealed to our honour in this matter of the caps, and hoped that 
we would do everything as became members of this ancient University. 
May 21. Walked into town at about 5 o'clock and there witnessed what 
we all expected would take place, namely, a row between the students and the 
rabble. There had been several all over the city, and every one was much 
excited. Nothing was talked of but the caps. 
May 23. Great preparations were made today for the mob which we 
expect tonight. Went out with Bradford and Parkman to cut a club after 
dinner. Went to walk with P. after supper, and while we were walking 
toward the Pond, the bell rang for fire, and thinking that it might be a pre- 
text for collecting the people together, we ran back. I left Frank at his 
house, and had got nearly down to the College when I heard a great shout- 
ing and breaking of glass, and thinking that the mob had attacked one of 
the buildings, I ran to the assistance of my Alma Mater. When I entered 
the yard I saw a most horrible sight, namely, the French room in old Massa- 
chusetts apparently on fire. The students soon collected round and with 
considerable exertion succeeded in putting it out, altho' it was confined to 
the closet. It was undoubtedly communicated by some miserable scoundrel 
who was ripe for a row. There is no building I would not sooner see go than 
that venerable old pile. I trust the Faculty will do all in their power to 
find the scoundrel out. Everyone expected a row tonight, and all were 
walking about the yard armed cap-a-pie. The night, however, passed off 
without disturbance. A watch of four was set by the college to prevent 
any further damage. 
June 30. There have been a great many " blowings up " lately. A 
bomb was found up in the belfry all ready to touch, containing several 
pounds of powder. It would have blown everything to atoms 
Attended a meeting of the N. History Society, one of the best societies in 
College, and was unanimously chosen Vice-President and Treasurer. 
July 6. There was one of the greatest outrages committed last night 
that has been perpetrated in this College. A large bombshell was placed 
in a small closet in Pierce's room, and exploded, literally tearing the room to 
atoms, also the hall of commons underneath and Bartlett's room. With so 
much violence did it explode that large beams were split, and several stones 
started on the outside of the buildingThe thickness of the 
bomb was about two inches, and Prof. Treadwell says that if it had been 
placed in the centre of the room the whole wing of the building would have 
been a mass of ruins. A meeting of the students, authorized by the 
President, was held after prayers, at which several resolutions were 
adopted and requested to be published in all the principal papers. 
Dec. 29. Four of us, Lord, Davis, Prescott and myself decided to go 
up to the ball at Lexington tonight, and were quite a load for one horse in 
a great arkDavis and myself shook hands with the girls we had 
seen there before, and they seemed delighted to see us. We immediately 
commenced dancing, about 9 o'clock, and kept it up till 3 a.m. The en- 
tire concern was on a larger and better scale than the last one. We had 
better music and plenty of girls. I introduced Prescott and Lord about. 8 
We did not get off from paying this time, but had to launch out our dollar. 
They kicked up such a most tremendous dust that our clothes were covered 
and our hair appeared grey. When we got through we found it snowing 
very hard, and that it was impossible to get home, so we were obliged to 
wait till daylight. We at last got under way for Cambridge, raining most 
tremendously, and arrived a little after 8 o'clock. Cut all the recitations 
this morning, as I felt so badly. Felt much better in the evening, so that I 
wrote quite a long report on the " skunk " for the N. History Society. 
After graduating from Harvard in 1844, Mr. Slade spent some 
months on a farm near Greenfield, but returned to Cambridge in 
the early winter, and became enrolled as a resident graduate. 
Here he became intimately associated with the historian, Jared 
Sparks, and was engaged under him in the copying of original 
documents relating to the American Revolution. In 1845 he en- 
tered the Harvard Medical School, and his success here decided him 
on the choice of medicine as a profession. During the summer of 
1846 he studied in the office of Dr. Amos Twitchell, and in October 
of that year witnessed the first capital operation under the influence 
of ether. This important event was afterwards described by Dr. 
Slade in an article published in the Historic Moment Series oi 
Scribner's Magazine (see list of writings below). It was at the 
Grove Street Medical School that our young physician first came in 
contact with Dr. Oliver Wendell Holmes, whose friendship he ever 
afterwards continued to enjoy. On receiving his Doctor's degree 
in 1848, he was appointed house surgeon at the Massachusetts 
General Hospital, where he served for one year. He then went 
abroad, remaining in all three years in Europe, most of his time 
being devoted to the study of his profession in Dublin and in Paris. 
The summer of 1851 was passed by Dr. Slade as a resident pupil 
in the Lying-in-Hospital at Rutland Square, Dublin, and he studied 
tw*o months during the fall at the National Veterinary School 
situated at Alfort, France. Returning in 1852, he began prac- 
tice in his native city, and opened an office at 5£ Beacon Street on 
the first of July. He became intimately associated with the late 
Drs. J. C. and J. M. Warren, and was one of the attending surgeons 
of the Boston Dispensary, in company with Drs. G. H. Lyman, 
W. W. Morland and R. M. Hodges. Throughout this period Dr. 
Slade had been a more or less regular contributor to medical jour- 
nals of articles relating to his profession, most of them being signed 
simply " Medicus"; and he was the successful competitor for four 
medical prizes, - the Boylston of 1857, the Massachusetts Medical 
for 1859, and the Fiske Fund for 1860 and 1862. Two of his 
prize essays have been published separately, their titles being 
especially noted below.* 
* " The quality of the work in these essays may be inferred from the quite remarkable 
history of one of them-Diphtheria; its Nature and Treatment. In spite of the promi- 
nence which modern discovery has given to the investigation of this particular disease, this 
prize essay of Dr. Slade's has been found of sufficient value and interest to be twice repub- 
lished, the last time in the present year, or thirty-six years after the award of the prize."- 
Dr. Z. B. Adams. Paper read before the Massachusetts Medical Society, June 10,1896. 9 
He was also one of the first to endeavor to raise the standard of 
veterinary surgery in Boston, and became the first president of the 
Veterinary Society. At the instance of the Massachusetts Society 
for Promotion of Agriculture, although he was then a very young man, 
his services were secured for the delivery of a course of lectures on 
veterinary science at the State House; and from time to time he 
"lectured upon the same and kindred topics at other places in the 
State. About this time he joined the Somerset Club and the Inde- 
pendent Corps of Cadets, and took up his residence at 17 Temple 
Place, Boston. In his domestic relations Dr. Slade was particularly 
fortunate. At King's Chapel, on May 27, 1856, he was married 
to Mina Louise, daughter of Conrad and Lisette Hensler. In his 
wife he found a helpmeet of rare devotion, who entered with en- 
thusiasm into all his projects, and whose counsel and encourage- 
ment he was accustomed to depend upon for a period of nearly forty 
years. Four sons and seven daughters were the fruit of this union, 
of whom one son has died. Of the happiness pervading his home 
life, it is unnecessary to speak; an index of it may be found, how- 
ever, in these words, which were jotted down by the Doctor in his 
diary on the occasion of his fiftieth birthday: 
My fiftieth birthday. Fifty years! It seems a good many, but after all 
what are they ? I am in health, and in the enjoyment of all needful blessings, 
- riches, in the form of a fond wife, and darling children, - as well as 
riches which the world calls wealthMy dear home, my dar- 
lings within it, as yet an unbroken circle! .... How ungrateful I 
am for these many blessings! God help me and make me better. 
During the war Dr. Slade was appointed special inspector of 
General Hospitals under the Sanitary Commission at Washington, 
D. C., and was otherwise occupied with undertakings involving 
great responsibility. 
In 1862 he removed with his family to Chestnut Hill, having been 
led to select this neighborhood from the fact that a small colony of 
personal friends had already settled there. Among these may be men- 
tioned John Lowell, Francis L. and George C. Lee, D. S. Curtis, 
and Leverett Saltonstall. Later he erected a substantial brick 
house upon the corner of Beacon and Hammond Streets, to the west 
of the old homestead, and laid out the surrounding grounds with 
taste and judgment. In a simple, unostentatious way, this com- 
fortable home was the scene of abundant hospitality; among those 
received within its doors may be noted such friends as George Tick- 
nor, Henry W. Longfellow, Thomas G. Appleton, Dom Pedro of 
Brazil, James T. Fields, Francis Parkman, Dr. O. W. Holmes, 
and numerous of his medical colleagues. 
After his removal to Chestnut Hill he began to relinquish gradu- 
ally the practice of his profession, and to devote himself more un- 
interruptedly to literary and horticultural pursuits. He was pas- 10 
sionately fond of flowers and plants, and it was his invariable habit 
to spend one or more hours each day in his garden or conservatory. 
His contributions on the subject of horticulture are numerous, in- 
cluding a charming little volume entitled " Evolution of Horticulture 
in New England; " and he was prominently identified with the 
Newton and the Massachusetts Horticultural Societies. 
April 12, 1871, Dr. Slade was appointed Professor of Applied 
Zoology at the newly established Bussey Institution at Jamaica Plain. 
He remained in all twelve years engaged in this capacity, and had 
the satisfaction of seeing his department take root and flourish under 
his direction. Nor was his efficiency limited to giving instruction 
alone, for in other ways he contributed materially toward strength- 
ening the early organization of the Institution. In 1885 the scene 
of his labors was transferred to Cambridge, owing to his appoint- 
ment as Assistant in Osteology at the Agassiz Museum. This posi- 
tion, with the coincident one of giving lectures in comparative 
osteology in Harvard College, he continued to hold up to the time 
of his death. During these years he performed a vast deal of useful 
service, and incidentally published a considerable number of sci- 
entific articles. The College was further benefited by his founda- 
tion of the Slade Scholarship, which represented a gift on his part 
of five thousand dollars; and he also contributed liberally toward 
the building of the new Harvard Medical School. 
As a lecturer, Dr. Slade was extremely popular, owing to his 
charm of speech and manner, and power of stimulating original 
observation on the part of his students. He seems never to have 
forgotten a lesson taught him by his own personal experience, name- 
ly, the necessity of looking to the natural objects themselves for the 
information they contain. The difficulty he had in mastering 
astronomy is recorded in his college journal, where numerous allu- 
sions are made to having "deaded" recitations. But one luminous 
entry reads as follows : " Nov. 17, 1843. Studied my astronomy 
with the aid of Smith's globe this evening, and thereby learned 
more than I have in all the time before." The extract is significant, 
since in his teaching he strenuously insisted that as much use be 
made of the actual specimens as possible, and for this reason his 
course in osteology had the reputation of being a most excellent 
one for training the powers of observation. 
The affectionate regard for him entertained by both students and 
fellow-workers is evinced by a large and interesting correspondence, 
which was terminated only by his death. Similarly, there are nu- 
merous warm expressions proceeding from time to time from his 
classmates, of which one instance only can be noted here. Serious 
illness having incapacited the Doctor from attending his class 
reunion in 1882, he was made the recipient of the following 
letter: - 11 
Dear Dan: - 
Your classmates assembled in 7 Holworthy join in this note 
to you, to say how much we miss your presence, how sincerely we sympa- 
thize with you in your illness, how we prize your friendship and love, and 
how near to our hearts is the desire that your life may by prolonged and 
your health fully restored.

But it was at his own fireside and within the circle of his own in- 
timate friends that Dr. Slade's innate nobility and refinement of na- 
ture were revealed at their best. His warm-hearted, sensitive dis- 
position, his rare sympathy and capacity for feeling, his culture, 
love of intellectual pursuits and companionship, his intense admira- 
tion of nature in all its forms, his perfect sincerity, uprightness 
and high moral principles - these were among his most marked 
characteristics. One who stands high in University councils and was 
long and intimately associated with the Doctor, has spoken of him in 
the following words : "His simplicity, directness and moral earnest- 
ness were strikingly apparent, and his strong desire to be of service 
was one of his chief characteristics. He was just and considerate 
in his relations to others, and he had a modest estimate of his own 
powers and labors. He was faithful in labor, friendship, love and 
duty." .... Other appreciative and tender expressions are 
not wanting, and especially warm tributes to his memory were paid 
by the Colonial, Bostonian, and the Historic-Genealogical Societies, 
of all of which he was an active member, at meetings held shortly 
after his death. Enough, however, has already been said to recall 
the fact to our minds that the life which has recently closed was one 
of exceptional worth, full of honor and usefulness; one such as was 
in keeping with high ideals of Christian character, and whose 
emulation cannot but be fraught with blessing. 
" His life was gentle; and the elements 
So mix'd in him, that Nature might stand up 
And say to all the world, This was a man! "
