Many will suggest an improved system of sewerage as the great 
desideratum; others will admit the necessity, but supplement certain 
requirements in plumbing devices; another adds to these certain theories 
about ventilation; and yet we find, in spite of all these precautions, the 
evil still appears, and the various zymotic diseases, the outcome of sewer 
gases, continue to swell the mortuary lists of all our large cities. 
In the Popular Science Monthly of November, 1882, an article ap- 
peared, contributed by Professor Frank H. Hamilton, of New York, in 
which some twenty pages are devoted to the subject of sewer gas. Care- 
fully perused, it must influence the minds of those who hitherto have been 
only partially informed, or a good deal skeptical as to much that has 
been said and written regarding the dangers that cluster around our 
modern conveniences. 
Reviewing the opinions and theories of the most celebrated sani- 
tarians, sanitary engineers, physicians, and others who are deemed 
authorities upon the subject, giving due consideration to all the latest and 
most approved methods of protection by mechanical means alone, his 
researches and experience force the conclusion that certain immunity from 
the baneful effects of this dangerous element can only be secured by either 
removing entirely from our living-rooms all connections with the drainage 
system of the house or by counteracting and destroying this evil influence 
through the use of proper chemicals. The opinions expressed have been 
freely indorsed by Professor R. Ogden Doremus, Professor Willard 
Parker, Professor Jos. G. Richardson, Dr. James R. Nichols, Dr. Wni. 
Hunt, S. P. Sharpies, Esq., several of the principal Boards of Health, 
and many other eminent men who have no specialty, pet scheme, or hobby 
to push to the front. 
In view of the unsatisfactory results of the mechanical system, we 
find Colonel George E. Waring, perhaps the most celebrated of all our 
sanitary engineers, reported as having conditioned all mechanical con- 
trivances with what is so seldom attained, perfection. That is, he thinks 
with simplicity and perfect construction, perfect material, perfect work- 
manship, perfect ventilation, and the utmost care and attention as to 
cleanliness, we may be safe. When we have reorganized human nature, 
this arrangement of perfections may be utilized, hardly before. 
These contributions to the somewhat limited stock of literature upon 
this theme, embodies all that is essential, and thoroughly corroborates 
what has been previously set forth as well-established theories by the most 
eminent authorities in this and other countries. 
The disease germ is the product of decomposition—the result of a 5 
chemical change in the material wherein it originates. To successfully 
combat it and the gases in which it tloats, “ we must kneel at the shrine 
of chemistry,” and employ such chemicals as will antagonize them, and 
decompose and destroy their power to do harm. 
There is no safety or security in any other method. 
The first practical attempt yet, made in this country or Europe to 
publicly introduce chemical disinfection into houses by a systematized 
plan is by the “ Geiimicide.” This is a small, neatly finished walnut 
case (see cuts and full explanation on cover), easily attached behind the 
lid of water-closets, which, without requiring any attention from the 
inmates of the house, supplies a constant flow of a solution of chloride of 
zinc (Burnett’s fluid), through the closet and discharge pipes. This pow- 
erful agent is continually flowing, whether the closet is in use or not; it is 
acting upon the noxious gases which may arise from the sewer or other 
sources of contamination by pipe connections. The air of the room is also 
purified by a contrivance which gives off the vapor of thymol. 
The “Germicide,” being automatic in action, does not rely upon 
attention from the house inmates. It is examined and supplied with chemi- 
cals regularly once a month by uniformed inspectors. 
By its use disinfection is effected in a continuous way; it furnishes 
the antidote to poisonous emanations which, notwithstanding the most 
perfect plumbing and ventilation, enter the house, causing diphtheria, 
malaria, and countless other diseases. 
The appliance always remains the property of the Company. The 
nominal charge made for the monthly supply of chemicals places this 
needed sanitary apparatus within the reach of all. 
Henceforward, the dreadful dangers growing out of our modern 
conveniences can be readily and cheaply averted, and the atmosphere of 
the most unwholesome adjuncts of our dwellings maintained perfectly 
pure, sweet, and healthful. 
Persons desiring to investigate The “Germicide” System will be 
granted every facility and explanation at the office of the Company, or 
they will be called upon by competent representatives by sending noti- 
fication of such desire to

“ Every one puts a lightning-rod on his house to guard against 
a danger that rarely occurs. A ‘Germicide’ protects you from 
dangers that are always present, and which attack you unheralded 
and unseen.” 
IMPORTANT STATEMENTS. 
PROFESSOR TYNDALL says: “ The disease germ is the product 
of decomposition, the result of a chemical change in the material wherein 
it originates.” 
PROFESSOR FRANK H. HAMILTON, of New York, in the Pop- 
ular Science Monthly for November: “I. The offensiveness of odors is 
no test of their insalubrity, but the most fatal germs are conveyed in an 
atmosphere which is odorless. The absence of unpleasant odors there- 
fore furnishes no proof that the air does not contain sewer emanations. II. 
He conclusively proves that plumbing devices do not effectually keep 
out sewer air, and agrees with Professor Doremus, who advises the con- 
stant and free application of disinfectants, of which it is unscientific to 
say they merely ‘ disguise bad odors for, if it be true that they do not 
cause directly the death of all germs, it is nevertheless true that they pre- 
vent putrefaction of organic matter, and thus destroy the aliment upon 
which germs subsist and by which they are made to multiply. III. What 
is sewer gas? What has been called sewer gas is composed of air, vapor, 
and gases in continually varying proportions, together with living germs, 
vegetable and animal, and minute particles of putrescent matter. IV. 
Sewer gas fertilizes the human soil, and renders it more capable of receiv- 
ing and developing the germs of specific disease. V. Typhoid fever has 
long been known to be caused by sewer emanations.” 
PROFESSOR RICHARDSON, of the University of Pennsylvania : 
“ I. According to the germ theory of disease, . . . diphtheria, ty- 
phoid fever, scarlet fever, and probably other contagious diseases, are con- 
nected with, if not solely due to, the development of spores or germs of 
vegetable organism in the human body. II. These germs propagate in 
sewers, and float to us on the sewer air, penetrating into our dwellings 
through water-closets, sinks, etc. . . . III. The true method of ob- 
viating this danger is by sterilizing with slow currents or drippings of 
solutions of sulphate of iron, corrosive sublimate, chloride of zinc, etc., 
the whole interior of our waste-pipes.” 7 
PROFESSOR BARKER to the New York Academy of Medicine: 
“Sewer-gas malaria had often been found to complicate scarlatina and 
render fatal an attack which might otherwise have ended in recovery.” 
ELLIOT C. CLARK, of Boston, the great sanitary authority, states 
that there is more danger from the soil pipes and trapping system of a 
house which become befouled with feecal matter than from the sewer, and 
that chemical purification is the only remedy. 
I)R. ANGUS SMITH states that the proper method to adopt to pro- 
tect our homes from foul gases impregnated with the germs of disease is 
to deal directly with the matter about to decompose and prevent decom- 
position by the use of a disinfectant. 
DR. ELWYN WALLER, Chemist of the Metropolitan Board of 
Health of New York, and one of the highest authorities in this country 
on disinfectants and antiseptics, states that chloride of zinc is of great 
value. It not only prevents decomposition, but absorbs gases which arise 
from same. 
PROFESSOR LIONEL L. BEALE, M. D., F. R. S., has said: 
“ The only thoroughly efficient mode of disinfecting sewerage is by adding 
the disinfectant in each house, and so effecting the change before it 
becomes sewage.” 
T. PRIGDON TEALE, Leeds, Sanitary Maxims, third edition: 
“ Whenever gas from sewers or the emanations from a leaky drain . . . 
make their way into a house, the inmates are in imminent danger of an 
outbreak of typhoid fever, diphtheria, or other febrile ailment classed 
together under the term ‘ zymotic,’ not to speak of minor illness and 
depressed vitality, the connection of which with sewer gas is now fully 
established. Sewer gas enters a house most rapidly at night when outer 
doors and windows are shut, and is then, perhaps, most potent in contami- 
nating the meat, the milk, and the drinking-water, and in poisoning the 
inmates.” 
“THE POPULAR SCIENCE NEWS AND BOSTON JOUR- 
NAL OF CHEMISTRY,” edited by I)r. J. R. Nichols, of Haverhill, 
Mass.: “In only two ways can aid be secured in removing the dangers 
arising from any system of city sewerage: First, by mechanical devices 
which will allow the free outflow of liquid and solid waste and at the 
same time absolutely prevent the inflowing of the secondary products 
arising from vital and disorganizing chemical action; and, second, by the 
use of chemical agents. The vast number of traps, valves, automatic plugs, 
bent tubes, etc., used in houses have resulted from efforts among plumbers 
and inventors to meet the difficulties of the situation by the first method. 8 
“ It may be said that some degree of success has crowned the efforts 
of mechanicians to obviate sewage perils; but the success has been by no 
means what the gravity of the situation demands. At present there does 
not appear to be a single mechanical appliance known which effectually 
under all circumstances affords immunity from the return of deleterious 
gases and disease germs into dwellings. 
“ The working out of the problem in mechanical directions affords 
no promise of success and may as well be abandoned. We must turn to 
the chemist for aid, and all the resources of his art must be brought into 
requisition to meet the emergency. That chemists have not been indiffer- 
ent in providing agents for thorough disinfection is shown by the long 
list of important antiseptic substances which have recently been brought 
to notice. . . . 
“ Recently our attention has been called to a new device, which is 
very simple, and yet it meets fully all requirements. It is called a Ger- 
micide, or germ-destroyer, and is designed to be applied to water-closets, 
so that by its use a constant flow of zinc solution is maintained and perfect 
disinfection is secured. . . . It is worthy the attention of all house- 
holders whose dwellings are connected with city or town drains.” 
PROFESSOR VARONA calls house drains “a small system of 
sewers within the dwelling,” and adds: “The invisible portions areas 
much out of mind as they are out of sight.” 
“ Disinfection is the application to or contact with noxious ma- 
terial of such chemical agents as will produce its decomposition 
and restore it into harmless forms.” 9 
“ Phases of Sanitary Science.” 
One of the complaints urged against sanitary engineers by practical 
plumbers is that they cannot agree upon fundamental principles and are 
altering their requirements from year to year. ... A house that is 
built in accordance with the approved specifications of the most competent 
engineers will 1)3 condemned within five years by the same authorities as 
faulty in its sanitary appliances. . . . Mr. George E. Waring, Jr., 
in the current number of the American Architect, says that “ flushing ” is 
the watchword of the best sanitary science of the present time, and con- 
fesses that he has little faith in the universal specific of trap ventilation 
and kindred appliances. Now, the separation of the drain-pipe, with its 
volume of air an 1 gas 's, by means of water-seals and other devices, simple 
and complex, from tli3 atmosphere of the house has been one of the chief 
aims of the sanitary engineer. A thousand and one traps and mechanical 
obstructions have been invented for this purpose, and at least a hundred 
of them have been pronounced absolutely safe by competent authorities. 
In every house erected under the new sanitary codes . . . the main 
drainage-pipes are required to be trapped, aud the cost of plumbing in 
this and in other respects has more than doubled during the last fifteen 
years. 
Yet here is Mr. Waring, one of the leaders of sanitary science, 
blurting out his want of faith in these costly appliances. The system of 
ventilating-traps, ho says, is attended with dangers equal to those which 
it is intended to remove, and mechanical traps are a makeshift also, which 
become seats of decomposition unless they are kept constantly under the 
eye and copiously flushed. 
It is a singular fact that in spite of the thousand inventions in 
plumbers’ appliances, . . . the best advice which one of the most 
accomplished engineers has to give to house-builders is to have as little 
work of this sort as possible.—Editorial New York Daily Tribune, Sept. 
20th, 1883. 
There need, however, be no despair—no such word as “impossi- 
ble ” in our search for safety. The resources of science and the 
ingenuity of man must be equal to the demands for complete protec- 
tion. The true remedy is not likely to be found in mere mechanical 
means, however perfect (for there are points of danger which mechan- 
ism does not cover), but in a combination of good plumbing with such 
chemical agents as are certain to destroy or prevent the formation of 
disease germs, impure air, etc., which are beyond the reach of the 
plumber alone. 10 
SCIENTIFIC VALUE OF THE DISINFECTANTS USED IN 
THE “GERMICIDE.” 
Chloride of Zinc. 
The constant supply of a solution of chloride of zinc, flowing from the “ Ger- 
micide” into the water-closet trap, and thence through the drainage system to the 
sewer, impregnates the water of the trap with a chemical which destroys the life of 
germs, thus rendering them harmless. 
BUCK’S “HYGIENE” (pp. 561-562) says: “The metallic salts stand first as 
disinfectants for liquids containing any matter of a dangerous character. They arrest 
putrefaction and destroy infectious matter. . . . The best disinfectants among 
them are the zinc and iron salts. They usually are to be obtained as sulphates or 
Chlorides. Of these the former are the most common, while the latter are preferable.” 
“UNITED STATES DISPENSATORY,” Fourteenth Edition (p. 1316), says: 
“ Burnett’s disinfecting fluid, like the officinal solution, is an aqueous solution of 
chloride of zinc. It is so called after Sir William Burnett, who introduced it into 
use in 1840 as a powerful deodorizing and disinfecting agent in neutralizing noxious 
effluvia and in arresting animal and vegetable decomposition. . . . The con- 
cun ent testimony of a number of observers shows that it acts as an excellent disin- 
fectant for ships, hospitals, dissecting-rooms, water-closets, privies, etc.” 
“CYf'L. OF CHEMISTRY” (Yol. I, p. 617) says: 11 Chloride of zinc and the 
other metallic chlorides absorb ammonia and sulphuretted hydrogen, and are useful- 
as disinfectants of faecal matter. . . . Chloride of zinc, in the proportion of one 
part to 300 of water, destroys infusorial life; diluted to but one part in 1,000 of 
inorganic liquid, it will check decomposition for a considerable time.” 
R. S. G. PATON, PH. D., Chemist of the Health Department, Chicago, HI., 
says: “1. The first property of chloride of zinc as a disinfectant lies in its either 
directly hilling the disease germ by coagulation, or indirectly by making its food 
indigestible. 2. Its second property is its action on such gases as ammonia, sul- 
phuretted hydrogen, or ammonia sulphide, forming with these salts, which are not 
liable to be thrown into the atmosphere. 3. Its third property, changing these gases 
into solid substances. The vehicle (these gases) for carrying bioplasm (germs) into 
the air cannot be supplied.” 
PROFESSOR JOSEPH (i. RICHARDSON, M. I)., of the University of 
Pennsylvania, etc., says that chloride of zinc is one of the best disinfectants known. 
(See his letter.) 
PROFESSOR WILLIAM HUNT, M. IL, Surgeon-in-Chief of the Pennsyl- 
vania Hospital, etc., has fully indorsed and recommends the use of chloride of zinc. 
(See his letter.) 11 
H. A. MOTT, Jr., PH. D., E. M., says: “ The disinfectant used is chloride of 
zinc, which is well known to be of great value. It forms witli the albuminous prin- 
ciples extremely insoluble compounds, and at the same time absorbs the gases which 
arise from same.” 
Its use is recommended by Dr. Elwyn Waller, Chemist of the Metropolitan 
Board of Health of New York, and one of the highest authorities in this country on 
disinfectants and antiseptics. 
S. P. SII APPLES, Esq., Chemist and State Assayer for Massachusetts, fully 
approves of these chemicals. (See his letter.) 
JAMES R. NICHOLS, M. 1)., editor and proprietor of the Popular Science 
News and Boston Journal of Chemixtry, says: “No one competent to form an opinion 
of the comparative value of agents used as disinfectants can doubt the superior effi- 
ciency of the salt of zinc used in the Germicide, or the value of thymol as an aerial 
agent used in connection with the zinc chloride.” (See his letter.) 
THOMAS C. MINOR, M. I)., ex-Commissioner of Health, Cincinnati O., 
says: “The chemical agents used in the workings of the Germicide are now uni- 
versally held to be the best and most powerful antiseptics.” (See his letter.) 
E. W. LAMBERT, M. I)., Medical Examiner Equitable Life Insurance Co., 
etc., says: “The antiseptic effect of zinc and thymol upon decomposing animal and 
vegetable substances is well known and generally recognized.” (See his letter.) 
J. H. RAUCH, M. D., President of the Illinois State Board of Health, recom- 
mends the use of chloride of zinc and thymol as disinfectants. 
PROFESSOR R. OGDEN DOREMUS, Professor of Chemistry and Toxi- 
cology in Bellevue Hospital Medical College, Professor of Chemistry and Physics in 
College of the City of New York, Chemist of the Medico-Legal Society, most fully 
indorses the use of these chemicals as applied by the “Germicide.” (See his letter.)

THE CINCINNATI HOARD OF HEALTH, 
THE BOSTON BOARD OF HEALTH, 
THE WASHINGTON BOARD OF HEALTH, 
THE BALTIMORE BOARD OF HEALTH, 
THE SAN FRANCISCO BOARD OF HEALTH, 
See their testimonial letters. 
And thousands of other authorities advocate and indorse the proper application of 
CHLORIDE OF ZINC. 
The “Germicide” system will not be introduced in any dwellings 
where the plumbing is found to be in a defective condition. 12 
Thymol. 
The offensive gases which sometimes exist are neutralized by thymol, which 
constantly issues from the Germicide. 
“THE DISPENSATORY OF THE UNITED STATES,” Fifteenth Edition 
(pp. 1433-4) says: “ Thymol.—This substance, which is officinal for the first time, has 
recently attracted considerable attention from its possession of antiseptic properties 
analogous to those of carbolic and salicylic acids and creosote, with which it is also 
analogous in composition. . . . The disagreeable odor of carbolic acid induced 
M. Bouilhon, a French pharmaceutist, to search among the analogous chemical pro- 
ducts in the hope of finding one which might have the important practical properties 
of carbolic acid without its disagreeable smell. Such a substance he found in 
thymol.”

various amount of antiseptics which would check the putrefaction of a liquid of a 
known composition. Smallest amount which prevented the development of bacteria:

PROFESSORS YOLKMAN AND RANKE (Munich): l‘Thymol does not exert 
any irritant action on the respiratory organs ” (like all other disinfectants, as chlorine, 
sulphurous acid, carbolic acid, iodine, bromine, etc.—Ed.)—Professors Volhman and 
Ranke. 
PROFESSOR RANKE (of Halle): “ From an experience of forty-one wounds 
dressed with thymol, the lecturer [Dr. Ranke, of Halle] concluded that the method 
leaves nothing to be considered as to its antiseptic effect, and that it answers better 
than the carbolic-acid dressing. Further, it has no poisonous properties.”—Medical 
Press and Circular, August 28, 1879. 
PROFESSOR C. SYMES: “ Thymol.—Dr. C. Symes has mode a few experi- 
ments upon thymol which are of interest, as this substance continues to be largely 
used.”—Braithwaite?s Retrospect for January, 1880, p. 229. 
“ The powerful antiseptic action of thymol, exceeding under some conditions that 
of carbolic acid, its small activity as a poison, about one-tenth of that of carbolic acid, 
and the absence of irritating effect when it is applied to the skin, all point to its use 
as a substitute for carbolic acid in the now well-known antiseptic treatment of sur- 
gical cases elaborated by Professor Lister.”—Id. 
“The present cost of thymol is about five times the cost of the best carbolic acid; 
but as me part of the former seems to do as much work as twenty-five parts of the 
latter, the advantage of the price is on the side of thymol.”—Id, 13 
PROFESSOR H. A. MOTT, Jr., PH. I)., E. M., says: '‘The vapor of 
thymol is more powerful than carbolic acid, is very pleasant and agreeable, and does 
not exert any irritant action on the respiratory organs.” 
R. S. «. PATON, PH. !>., etc., says: “Thymol is well known to be an ex- 
ceedingly powerful aerial antiseptic, and has not the objections of carbolic acid, 
namely, its strong odor and acid properties.”

IWpWHE highest tribute which can be paid to any device, or system pro- 
WW P°sillS lessen causes of diseases and death, and the one most 
f-j] calculated to inspire confidence, is its adoption in the houses of 
medical practitioners of world-wide reputation, who are constantly recom- 
mending the “ Germicide” to their patients. Hundreds of valuable auto- 
graph acknowledgments and indorsements from physicians, scientists, and 
others using the “Germicide ” may be inspected at any time, together with 
other matters of irnportanoe appertaining to the subject, which cannot fail 
to prove of great concern to persons feeling an interest in the subject. It 
can be shown that a substantial enterprise is projected, and one that should 
enlist the sympathy and support of every man and woman who has a 
thought for the welfare of their household. 
R. OGDEN DOREMUS, M. D., LL.D.,

Physics in College of the Cily of New York; Chemist of the Medico-Legal Society. 
Not only from theory, but from my own knowledge, sewer gases are devel- 
oped in our houses as well as received from the sewers; for warmth and moisture 
are known to facilitate the decomposition of impure materials, and as these con- 
ditions exist in our residences vile gases and disease-breeding germs must be 
produced. 
But certain chemical substances, if present, will check the production of said 
gases and germs. ... I know of but one device which accomplishes these 
important results, and where a constant flow of the chloride of zinc, dissolved in 
water, was made to pass through the water-traps and water-pipes; this was 
called the Germicide. . . . 
The poisonous agents which emanate from decomposing animal, vegetable 
and foecal matter are not always recognizable by the sense of smell, as is daily 
and sadly demonstrated, and as I know and feel most keenly in the recent loss of 
a beloved member of my family. Yet science can grapple successfully with 
these invisible agents. 
. . . I had the pleasure of discussing these themes with the members of 
the National Board of Health in Washington. I showed them your effective 
instrument, the Germicide, with its incessant flow of a solution of chloride of 
zinc 19 
Your Germicide has unquestionably prevented sickness and death in many 
homes in New York, Chicago, and Cincinnati, where thousands of these instru- 
ments have been introduced, and I congratulate you that the medical profession, 
as well us the public, are giving you such hearty support 
II. A. MOTT, Jr., PH. I)., E. M., 
Any means or device, then, which has for its object the destruction of 
these germs, or, better still, the prevention of such decomposition in matters 
which foster their growth and multiplication, should be met with great favor 
by all intelligent people. . . . 
The proper method to adopt then, to protect our homes from foul gases im- 
pregnated with germs of disease, is to deal directly with the matter about to 
decompose, and prevent decomposition by the use of a disinfectant; and this I 
find to be the principle of the Germicide. . . . 
It is with pleasure that I direct the attention of the public to tbe Germi- 
cide, as being the most economical and effective means known to secure health 
in our homes. 
OSCAR C. I)E WOLF, M. D., 
Commistioner of Health of the Citg of Chicago. 
... 1 have never given the indorsement of my name to a .single one of 
the many methods and systems designed to accomplish this puqiose, and which 
have been brought to my attention during the past four years. . . . 
From the experiments detailed by I)r. Patou and Mr. Thomas (President of 
the State Microscopical Society), and many of which 1 witnessed, I must concur 
in their opinion that, as at present constructed and used, traps, however well 
supplied with water, can only act as a very temporary obstruction to the passage 
of disease germs into our homes from the sewers with which they are connected; 
and, again, that it is entirely practicable to render the water in these traps so 
perfectly aseptic as to destroy disease-bearing germs thut come in contact with it. 
1 commend the system . . .as practical, economical, and scientific, and believe 
that if it were generally introduced into the homes of onn city it would protect 
each household so connected from many of the dangers of sewer gas, and would 
also render the air in our sewers aseptic and pure. 
SAM GEL II. DURGIN, M. I)., 
Chairman BOSTOX BOARD OF HEALTH. 
I have examined your apparatus called the Germicide, and have witnessed 
its operation. 
You seek by means of the Gf.rmtoide to complete the harrier by keeping 
the water seal so charged with the chloride of zinc, a well-known antiseptic, as 
to arrest and destroy those gases and germs which might otherwise pass through 
the trap and into the house. The principle is go<xl and the experiments shown 
me were highly satisfactory. 
I believe that if the apparatus should be brought into general use it would 
l>e the means of reducing the sick-rate from preventable causes. 
I therefore believe it my duty to make an exception of this case, and to 
give your apparatus a hearty recommendation. 20 
JOSEPH G. RICHARDSON, M. D., 
Professor of Hygiene and Demonstrator of Histology in the University of Pennsylvania, Philadelphia; 
a so, of the PHILADELPHIA BOARD OF HEALTH. 
Recently I have for the first time witnessed the operation of the Germicide 
apparatus. . • • 
The public benefits arising from a general adoption of this plan for con- 
tinuous antiseptwn would be almost incalculable, and even for individual patrons 
it affords, I think, when aided by first-rate plumbing, an absolute security against 
those dangers from sewer gas which, according to Professor F. H. Hamilton in 
the Popular Science Monthly for November, 1882, are so great and so imminent 
that it is advisable for us all immediately to go back in our civilization and 
abandon those modern conveniences of water-closets, bath-tubs and stationary 
wash-stands, which do so much at the present day to render life worth living. 
SMITH TOWNSEND, M. D., 
Health Officer, District of Columbia, Washington, D. C. 
The Germicide is designed to act as a purifying agent in houses by the 
application of chloride of zinc to the water seal in sewer traps. This object 
seems to be accomplished by the mechanism of the device, and I have no hesita- 
tion in commending its use. 
JAMES A. STEWART, M. D., 
Of the Health Department, Baltimore, says 
I have carefully observed the operation of the Germicide in the water- 
closets connected with the offices of the Police Department in the City Hall, and 
am free to say that I am both surprised and pleased with the complete success 
at this place. ... I shall recommend the introduction of the Germicide to 
every one. 
EXTRACT FROM REPORT OF THOMAS C. MINOR, M. D., 
Ex-Commissioner of Health, Cincinnati, Ohio. 
I carefully investigated the workings of the new antiseptic apparatus known 
as the Germicide. I have long been satisfied from personal observation and 
practical experience that none of the mere mechanical contrivances known as 
water traps, applied to soil pipes, will prevent the ingress of sewer gas into house 
interiors. ... 
The value of this invention can hardly he overestimated, viewed from a 
purely sanitary standpoint, and I confidently predict a largely decreased death- 
rate from zymotic diseases in those cities so fortunate as to secure the full benefit 
of its application. . . . 
During an official career dating back to 1873, I have never before indorsed 
any of the numerous inventions submitted for inspection, but cheerfully make 
this an exception to the general rule. 
CINCINNATI BOARD OF HEALTH. 
Having thoroughly examined into the working of the “ Germicide,” and 
having tested it fully, we have no hesitation whatever in recommending it to all 
those who desire to prevent the escape of sewer-gas into their dwellings: It has 
been one of the objects of the Board of Health, ever since its establishment, in 
1865, to discover some apparatus which would prevent the escape of poisonous 
gases through the traps of water-closets, into the dwelling houses of our citizens. 21 
The germ theory of disease has been clearly established in the public mind, 
and acknowledging this evil, it Inis been made a special object of the Board to 
find a remedy. Science and invention has sought to accomplish this end, by 
mechanical devices, in plumbing, ventilation, etc., but, as yet, with but partial 
success. To control this germ, it is necessary to destroy it, and that, it has been 
demonstrated, can only be done by the use of chemical substances. This has been 
accomplished by the constant How of a solution of Chloride of Zinc, as is done in 
the “ Germicide,” and whatever may escape the action of the Zinc is antagonized 
by the Thymol vapor discharged at the same time. 
Ciias. F. Klayek, President Board of Health. 
Ferdinand Sprinomeier, 
L. E. Bramble, M. I).f 
Members of Board. 
W. A. DOUGLASS, M. D., of the San Francium Hoard of Health, says: 
. . . This is to certify that in my opinion its method of distributing chlo- 
ride of zinc in the trap is the only way to destroy completely the germs of sewer 
gas. ... I am entirely satisfied with the result of its working, and would 
therefore recommend it to general use. 
S. I\ KIIAPPLES, Esq., Chemist and State Assayerfor Massachusetts, says: 
I have had the “ Germicide” in use at my office for some weeks. It has 
worked well. I think that besides furnishing a constant supply of a disinfectant, 
this apparatus supplies another very important need, that is, it keeps the traps in 
the pipe always full, and with a fluid that is death to all germs. Even the badly 
constructed traps that are siphoned off by a sudden flush of water will be kept 
filled by this apparatus. I have also had occasion to test the strength of the 
outflowing liquid at the time the apparatus was first applied, and after it had 
been in operation a month without renewal of the chemicals, and find that it is 
remarkably constant. I regard the invention as an excellent one and would 
recommend its use. 
DR. JAMES li. NICHOLS, of Haverhill, Mass., Editor and Projrrietor of the “Popular 
Science News ” and “ Boston Journal of Chemistry :” 
1 have very carefully examined this device, and have seen it in practical 
use for several weeks, and it is my opinion that it fully meets a sanitary need of 
the highest importance. The desirable end reached has not been hitherto at- 
tained, viz.: a method of slowly and constantly supplying to the bowl of water- 
closets a solution of chloride of zinc in sufficient quantity to sterilize any infec- 
tive germs which may find their way through water closets into rooms in dwel- 
lings. No one competent to form an opinion of the comparative value of agents 
used as disinfectants can doubt the superior efficiency of the salt of zinc used in 
the “Germicide,” or the value of thymol as an aerial agent used in connection 
with the zinc chloride. The important points attained in this device seem to 
me to l»e the employment of the zinc salt in amorphous form, so prepared that 
by the constant action of water it slowly dissolves, conveying to the pan of the 
closet enough of the salt to act effectively night and day without interruption. 
This constant action must prevent the ingress of living germs, not only into 
the water-pipes of dwellings, but, if the device is generally adopted, must aid in 
sterilizing the contents of the smaller, or even larger, sewers of cities. 22 
L. BOLTON BANGS, M. D., Visiting Physician, Charity Hospital, N. V., says: 
I am satisfied with the “Germicide,” and desire it to be kept permanently in 
my home. 
JOSEPH J. BURIAN, M. D., New York, says: 
The “ Germicide” has given me great satisfaction. It ought to be adopted 
in all houses as a safeguard against infection. 
CHARLES C. BRONSON, M. D., Cincinnati, says: 
I have had a fair test of the “Germicide” and find its disinfecting opera- 
tion perfectly satisfactory. 
A. B. BARKER, M. D, Cincinnati, says: 
I consider the “Germicide” a great invention and would recommend it for 
health, comfort, and otherwise. 
\VM. II. COOK, M. D., Cincinnati, says : 
I have watched, with some care, the “Germicide,” and take pleasure in say- 
ing that it does effectively the work of disinfection expected from it. 
MRS. DR. CURTIS, Chicago, says : 
Am pleased beyond measure with its value as a neutralizing agent. 
A. L. CARRICK, M. D., Cincinnati, says: 
I have tested them and find them entirely satisfactory. 
OSCARS. CORKER Y, M. 1)., of the Faculty of the College of Physicians and Surgeons, 
etc., etc, Baltimore, says : 
I believe that it has a future of great usefulness. 
L. M. DENMAN, M. D., Cincinnati, says . 
I take pleasure in testifying to its efficiency, and recommend its general 
adoption. 
D. M. DENMAN, M. D., Cincinnati, says: 
I think it one of the greatest inventions of the age. No house should be 
without one. 
D. W. IIARTSHORNE, M D., Cincinnati, says: 
I find that it accomplished just what is claimed for it, and most cordially 
recommend it as essential to health and comfort. 
JUSTICE HAYES, M. D„ Chicago, says : 
It is peculiarly valuable in preventing traps from being siphoned. 
WILLIAM HUNT, M. D., Surgeon Pennsylvania Hospital, etc., etc., Philadelphia, says: 
The “ Germicide ” is a decided success. I say this from observation and ex- 
perience. With many others, I have for a long time thought that the true idea 
of the purification of dwellings from noxious matters is a chemical one. Some 
method was wanting by which a reliable disinfectant in solution could be made 
to constantly percolate through the discharge-water system of a house. By this 
means poisonous matters, whether gases or germs, are altered or destroyed in a 
thorough manner, which is vastly superior to any mechanical methods I know 
of, to trap them out. The essential operation of the “ Germicide ” is to destroy 
or change so as to correct harming matter into harmless substance. That it 
does so, I have had practical prcxif This idea is deserving of the approval of 
all sanitarians and scientific men. That it will meet the approval of all who try 
it, whether scientific or not, I have no doubt. I see in it the most effectual way 
that has yet been presented for keeping disease-breeding material out of human 
habitations. 23 
B. J. Z IRWIN, M. D, Surgeon and Brevet-Colonel, U. S A., says: 
For more than a year I have had the apparatus in use, and every additional

it for many times its cost. 
THOMAS SHEARER, M. D., Baltimore, says:

ciple is correct—its construction simple and the result eminently satisfactory.

at any price. 24

management, and believe they answer the purpose for which they are intended.

tieiesms- INVESTIGATE 
EXPERIENCE CONFIRMS THAT 
I. Sewer-Gas enters all houses and that odor does 
not always reveal its presence. 
II. Receivers, Traps, Soil-Pipes, Etc., get be- 
fouled with faecal matter until they become 
seething cesspools, creating gases and disease 
germs far more deadly than the diluted gas 
from the main sewer. 
III. Traps do not exclude gases, owing to the ab- 
sorbing quality of water. Traps syphon and 
evaporate. 
IV. No Mechanical Device Known can effectually 
prevent the entrance at all times of sewer gas 
and its constituents into buildings. 
V. A Few Minute Germs entering a delicate con- 
stitution are as bad as a thousand. 
VI. Chemical Purification Automatically and 
Continuously applied to the drainage system 
of buildings insures Health, Comfort, and 
Safety. 
VII. The Deficiencies of water carriage and ventila- 
tion are all met by The “ Germicide ” System.
