PREFACE. 
 
 The actual existence of cholera, at the pres- 
 ent time, in France and Spain, as indicated by 
 its reappearance in Marseilles, Valencia, and 
 other places, renders its appearance in this 
 country very probable, and to know how to 
 prevent it from spreading over onr land be- 
 comes a matter of the utmost importance. A 
 review of its history and causes, we believe, 
 will contribute much toward this end; hence 
 this little book. It is not designed to be an 
 exhaustive treatise on the subject of cholera, 
 neither is it a scientific monograph designed 
 solely for the use of the medical profession. 
 It is written for the people, and an effort has 
 been made to place before them, in an unpre- 
 tentious manner, the latest and best opinions. 
 It is made of small size that it may serve as a

 companion to very many persons; and if by its 
 study any considerable portion of the people 
 are aroused to the importance of individual 
 effort and cooperation with their Boards of 
 Health in sanitary matters, its object will have 
 been attained. While we are writing, reports 
 come from across the water of the gratifying 
 results of inocukition for the prevention of 
 cholera. In time this may, perhaps, prove of 
 as great value as vaccination, but for the pres- 
 ent our reliance must be upon sanitation. 
 
 The author desires to acknowledge his in- 
 debtedness to other writers from whom he has 
 freely quoted, but to whom he has endeavored

CHAPTER I. 
 
 CHOLEEA — ITS HISTOEY. 
 
 Cholera is a disease which is looked upon 
 by different persons with varying emotions; to 
 those who have read of the terrible ravages 
 produced by it in certain localities, or have 
 seen the streets deserted, business suspended, 
 and death regnant in a city, have heard the 
 rattle of the death- cart as it bore to the hastily 
 made grave, victim after victim of the fearful 
 scourge, it produces feelings akin to terror. 
 To those engrossed in business, with no 
 thought but for the accumulation of wealth 
 or position, it brings but a momentary anxi- 
 ety, which is at once lost in the busy whirl, 
 just as are the cry of the injured, the wail of 
 the oppressed, and the moan of the smitten. 
 But to those of the community who comprise 
 
8 Cholera. 
 
 the considerate and earnest class; who regard 
 the welfare of others as somehow very closely 
 related to their own; who are accustomed to 
 look upon life as a grand opportunity for the 
 growth and development of the principles of 
 good; and upon the various tribulations which 
 come to individuals and peoples as in some 
 way subserving this end, and, for this reason, 
 to be manfully accepted, studied and made to 
 divulge their secret, to such persons it brings 
 much anxiety, is the cause of much serious 
 reflection, but at the same time inspires to 
 earnest work. Too much admiration cannot 
 be felt for the army of patient investigators 
 who, regardless of their own comfort, zealously 
 labor to bring to light the hidden causes of 
 evil, that they may be removed. It is inter- 
 esting to study the reflections and review the 
 work of such persons, and contemplate the 
 advantages which accrue to society and the 
 world by reason of them. In the history of 
 cholera epidemics these facts are emphasized, 
 for, as Dr. Simmons in his elaborate report of 
 
Its Histoey. 9 
 
 the epidemics in Japan, quoting Macpherson, 
 says, "It is one of the oldest diseases whereof 
 a distinct description exists and there are few 
 disorders respecting which such an uninter- 
 rupted chain of evidence has been preserved;"* 
 and we might go further and state that in this 
 complete record we find the strongest evidence 
 of the value of careful study into the nature 
 and causes of those evils which produce wide- 
 spread devastation and of the prompt applica- 
 tion of such measures as reduce the evil to a 
 minimum. Centuries ago it was looked upon 
 as a visitation of the wrath of the gods and a 
 means by which vengeance was wreaked upon 
 unhappy mortals. When an epidemic was 
 raging furiously the most abject terror seized 
 upon the people and, they becoming panic 
 stricken, nothing was done and they died by 
 thousands. 
 
 Later, in Japan, the disease was generally 
 attributed to diabolical agency; "Hence the 
 people gave it the name of 7co-ro-ri; that is, 
 
 * Cholera Epidemics in Japan, by D. B. Simmons, M. D. 
 
10 Cholera. 
 
 'fox, wolf, and badger.' It was also believed 
 that all water and all fish were poison, so that 
 people dared not draw water even from the 
 pnre stream of the upper Tamagawa, nor eat 
 any fresh fish, even when it was brought to 
 their doors alive. Each one adorned his gate 
 with branches of pine and bamboo, and straw 
 ropes, and prayed that so dreadful a year 
 might pass away as quickly as possible; some 
 praying to kame and some to Buddha."* Lit- 
 tle was known of it then except its fearful mor- 
 tality; now the circumstances under which it 
 thrives are most completely understood, and 
 sanitary measures are undertaken which, in 
 many instances, are sufficient to stamp it oiit 
 at once. 
 
 The disease is indigenous to Asia and, al- 
 though attempts have been made to prove that 
 the first cases in the epidemic which prevailed 
 in some portions of France last year, originated 
 de novo in that country, it is pretty generally 
 regarded as an Asiatic disease, and appears in 
 
 *Op. cit. 
 
Its History. 11 
 
 other countries in accordance with the sequence 
 of given circumstances. Away back in the 15th 
 century it is reported to have existed, and de- 
 scriptions by some of the medical solons of that 
 period bring to our mind very clearly the so- 
 called typical symptoms of Asiatic cholera, as 
 we know them to-day. 
 
 Cormack, in his "Studies," mentions the 
 fact, as having been reported by Dr. John 
 Webster, that in the days of Sydenham and 
 Morton (1669-93) the population of London be- 
 ing at the time (1669) but 600,000, the deaths 
 from this disease were 4,385. But it is not 
 quite certain that this was Asiatic cholera, and 
 indeed the medical men of that day themselves 
 called it cholera morbus. In Hindoo writings 
 we have descriptions of it in the 16th and 17th 
 centuries, but they are unreliable as they con- 
 fuse other kindred diseases with it. During 
 the years of 1768 to 1769 there was an epidemic 
 of a disease closely resembling cholera which 
 proved extensively fatal, carrying off some 
 60,000 x^ersons. " On this occasion," as quoted 
 
12 Choleea. 
 
 by Simmons, "the spread of the disease was 
 so rapid, and the deaths so frequent, that the 
 carpenters were unable to keep up with the 
 demand for coffins, and empty sake casks had 
 to be employed for the purpose. The grave- 
 yards were at length all filled up, no space re- 
 mained for more burials, and the priests of the 
 various sects refused to permit the interment 
 of the remains, insisting that the bodies should 
 be burned and only the ashes buried. At the 
 various cremation grounds, therefore, coffins 
 in countless numbers were seen piled on top of 
 each other; the burning of bodies being done 
 in regular succession, according to the order of 
 their arrival. Numbers of corpses, mostly of 
 poor persons, had to be left unburied for up- 
 wards of half a month, and the headman of 
 the ward was at his wit's end to know what to 
 do in the matter. They were finally, by order 
 of the government, wrapped in mats and, 
 after a brief religious ceremony, were conveyed 
 to the Bay of Yedo, and sunk in the sea." 
 But, coming down to the year 1817, we find 
 
Its History. 13 
 
 reliable information to the effect that in this 
 year the disease which had hitherto been con- 
 fined to India, girded up its loins, overspread 
 the whole peninsula, and penetrated wherever 
 mortals lived, leaving in its course the ghastly 
 corpses of millions of victims. For live years 
 this giant stalked abroad; starting from Bengal 
 he turned his face toward the setting sun; 
 ascending the Granges, through Central India, 
 across the Ghauts Mountains; in one year he 
 reached the western coast of the peninsula. 
 Then to the southward to Madras in 1819, 
 crossed the sea to Ceylon, and during this year 
 visited other islands of the sea. Ubiquitous or 
 omnipresent, whichever he may be said to have 
 been, the Island of Sumatra, the Peninsula of 
 Mallaca, Siam and the Barman Dominions, did 
 not escape his ravages. From having been in 
 Northern China and Tartary in 1820, in 1821 
 he appeared upon the shores of the Persian 
 Gulf; from here he ascended the Tigris and 
 the Euphrates, and in 1822 passed over the 
 desert into Syria. Making his way northward 
 
14 Cholera. 
 
 through Persia, he reached the shores of the 
 Caspian Sea and captured the Russian City of 
 Astracan in 1823. The whole of Asia having 
 been made to pay tribute in victims to him, he 
 disappeared, apparently satisfied with the de- 
 vastation he had caused. But, like many 
 another conquerer, his success on this cam- 
 paign only whetted his desire for conquest. 
 In 1828 we see him knocking at the doors 
 before the town of Ohrenburg, in Russia, and 
 in 1830 he entered the city of Moscow; no 
 terrors of the conflagration were greater than 
 those produced by his appearance. In the 
 midst of gayest revelry the face was blanched 
 by the midnight cry of mourning and of woe; 
 where, but a few hours before, all had been 
 prosperity and gladness, now there reigns a 
 terror as of death. Through the streets of the 
 city, into the hovel of the serf and the palace 
 of the rich, he goes without let or hindrance, 
 beckoning here the old grandfather, there the 
 new-born babe, or again a whole family to fol- 
 low him, making great seams and chasms in the

 hearts of thousands. Hastening on westward 
 he attacked St. Petersburg, Warsaw, Dantzic, 
 Berlin, Hamburg, and crossed to England in 
 1831. 
 
 He appears to have taken to himself the 
 power of self-multiplication, for at this time 
 he appears in Paris, London, Quebec and Mon- 
 treal; he has overleaped the barrier presented 
 by 3,000 miles of water and attacked a new con- 
 tinent. As now we approach within the ken of 
 those who are living to-day, and perhaps 
 within the sacred precincts of some recollection 
 saddened by the loss of friends, let us drop 
 the figure and quietly follow the march of the 
 terrible scourge. On the 24th of June, 1832, it 
 appeared in New York and spread both north- 
 wardly up the Hudson, and southwardly to 
 the Delaware and Chesapeake Bay. About 
 the time when, under other circumstances, the 
 good old burghers in the city of Albany would, 
 in their quiet old-time way, have been cele- 
 brating the day of our Nation's pride, the 
 authorities were busy devising means to stay

 the approach of a disease which had already 
 made havoc among the poor of their sister city 
 The scourge found them as though it had 
 come "like a thief in the night." They had 
 neglected the proper precautions and the fell 
 destroyer entered upon h is ghastly work The 
 same is true of other cities in our fair land; 
 Philadelphia, Baltimore and St. Louis were all 
 sufferers that same month. For nearly two 
 years there were a few cases here and there in 
 this country and then it entirely disappeared. 
 In the meantime Syria, Arabia and Egypt were 
 invaded until, finally, having exhausted itself 
 seemingly, the disease disappeared from view 
 This was only its season of rest and recupera- 
 tion however, for in 1847 accounts were received 
 that it had a third time left its home in the 
 delta 01 the Ganges, taken up its march of 
 conquest and was pursuing the same route it 
 had on previous occasions. Passing with 
 terrible destruction through the cities of Persia 
 it reached Astracan and Moscow, in which 
 latter place it rested for the winter With 
 
Its History. 
 
 17 
 
 the advent of spring it attacked St. Peters- 
 burgh, Berlin, Hamburg, Edinburgh and Lon- 
 don; thence to New York and New Orleans. 
 At the former American city it was checked 
 by quarantine, but in New Orleans, the weather 
 being very hot, and other things favorable for 
 its reception and propagation, cases multiplied 
 rapidly, and soon it had extended into Texas 
 and up the Mississippi to Memphis. The next 
 year (1849) following its appearance in Europe, 
 it broke out in New York, Philadelphia and 
 many other places on the Atlantic coast. 
 Starting afresh in New Orleans, it overspread 
 the valley of the Mississippi, took up its habi- 
 tation with those who were toiling over the 
 plains to their El Dorado, and caused many an 
 one to stay his westward course and lay himself 
 down to die amid the sage brush and the cactus. 
 It reached Sacramento; it went even to the 
 Golden Gate and there it rested. Not from 
 thence departed, for during nearly six years 
 there were cases frequently appearing in this 
 country, milder exhibitions of the epidemic at

 various points, until finally we find ourselves 
 relieved of the oppressive visitor. A fourth 
 time India sent her poisonous breath through- 
 out the continent and slew more victims than 
 the armies of Europe's conquering hero 
 claimed. Reaching Mecca in 1865, the pesti- 
 lence found a rare place in which to thrive. 
 It is a sacred place and sacred season; Moham- 
 med's loyal followers have met for worship at 
 their shrine. Weary and worn by their long 
 pilgrimage, poor in purse and wretched in con^ 
 dition, they exist in the midst of squalor most 
 profound. An official from the temple brings 
 them "cakes of sacred bread; these cakes were 
 made of meal, one- third of which is composed 
 of sand and grit, and the remnants of obnox- 
 ious insects. Another day the food is half- 
 boiled rice, not cleared of gravel, bran or grit, 
 and little cakes made of this with old and 
 rancid glue. To render this food more sacred 
 the cakes are kept in the temple for some days 
 before they are consumed. Having been thus 
 offered to the presiding deity of the place, they

 must be eaten by the pilgrims and that with 
 apparent relish, for it is sacrilegious to exam- 
 ine too closely the composition, and it is blas- 
 phemy to find fault with it at all."* " The 
 city of Mecca, lying in a basin, contains a 
 permanent population of about 40,000 souls, 
 and annually, during the Hadj (pilgrimage), 
 from 100,000 to 150,000 pilgrims, who become 
 residents for periods varying from one week 
 to three months, crowd into it. This vast in- 
 flux of strangers finds accommodation where it 
 can; the well-to-do rent rooms, the poor live 
 in the streets. The houses in Mecca are 
 generally built in fiats to accommodate pil- 
 grims; each flat is provided with one or two 
 badly constructed latrines, and there are from 
 six to twelve of these in each house. These 
 latrines empty themselves into pits dug out- 
 side the houses; when these get filled they 
 are emptied into other pits, which are made in 
 the streets or any other convenient spot, and 
 then covered over with earth. For the poor

 latrines are made on the same principle, in and 
 outside the town, and the same method of 
 emptying them is employed. This system of 
 burying foul matter in every direction has 
 been pursued for centuries; it is not, therefore, 
 surprising that the ground in and around 
 Mecca is surcharged with excrementitious 
 matter, which rains (these are frequent in 
 Mecca) carry by filtration into the wells. One 
 of the principal of these, and one most used, 
 is called Hagar's well; it is not a spring, but 
 its water is supplied by filtration— that is, by 
 rain-water passing down through an overly- 
 ing mass of foul matter. In addition to this, 
 pilgrims by the thousand, sick and well, 
 diseased and sound, daily wash beside it, when 
 the water used naturally finds its way into the 
 well."* What better allies could cholera have 
 than such food, such water, such houses and 
 such squalor? Re-enforced at this point, it 
 passed into Egypt, making fearful ravages in 
 Cairo and Alexandria. Dividing here, it

 moved along the coast of Syria and Asia Minor 
 up to Constantinople, encircling the Black Sea 
 in its embrace; at the^same time visiting Italy 
 it spread along the coast and into the interior. 
 During the month of October it attacked 
 Gibraltar, Barcelona, Madrid and other jDlaces 
 in Spain, as also Marseilles, Toulon, Paris and 
 other places in France, getting into England 
 just as the frost came. From that time for- 
 ward, for twelve' years, certain places were 
 subject to outbreaks of cholera; in 1866-67 it 
 made its appearance in New York but was at 
 once stamped out. Too much praise cannot be 
 awarded to the health authorities for the 
 prompt and efficient action taken at that time; 
 quite a large number of cases occurred in New 
 York, Brooklyn and the harbor, but the 
 spread of the disease was prevented and no 
 panic was caused. Compared with the epi- 
 demic of 1849 in New York, when cholera was 
 allowed to exist from December to the early 
 part of May without any attempt being made 
 to put the city in as good sanitary condition 
 
22 Cholera. 
 
 as possible and in consequence nearly 5,000 
 deaths occurred, it is a brilliant illustration of 
 the value of local hygienic measures. In 
 1877-79 China and Japan suffered severely, 
 and the excellent report we have of that epi- 
 demic* makes very clear the necessity of 
 promptly putting into execution the best 
 measures for preventing the entrance of a dis- 
 ease to a country. The reports of the last 
 epidemic in Naples, as published in the 
 "Medical News,"t furnish the same line of 
 evidence. "August 2, 1884, the first case of 
 cholera was reported in Naples, and the 
 patient removed to the Conocchia Hospital, 
 where he died. From that time the disease 
 made gradual progress, of the course of which 
 there was no official report, the fact of the 
 existence of cases being published in a desul- 
 tory way, no particular importance being 
 attached to them, seemingly. They were said 
 to have been sporadic and no fear was felt as

Its History. 23 
 
 to their spreading so late in the season. There 
 were others who thought the disease was 
 smothered for the time being, to break out with 
 renewed force in May, 1885, when they ex- 
 pected a gradual increase, followed by an out- 
 break similar to that of 1836-37. 
 
 The disease finally manifested itself in a de- 
 cided manner on August 23. The former indif- 
 ference of the authorities was changed to the 
 greatest activity and anxiety; the portion of 
 the city most exposed to the fury of the dis- 
 ease was the Parto. It rapidly spread to the 
 Mercato, Pendino, and Victoria, the former of 
 which outstripped the Parto in the number of 
 deaths, and has maintained the foremost posi- 
 tion during the epidemic. On the 11th of Sep- 
 tember the highest point was reached, the bul- 
 letin of that day giving 949 fresh cases and 357 
 deaths; this was followed by 843 fresh cases 
 and 386 deaths on the 12th, 698 cases and 281 
 deaths on the 13th, from which date there was 
 a gradual decrease in both cases and deaths. 
 On September 22 the cases had fallen to 305 
 
 3 
 
24 Choleea. 
 
 and the deaths to 97 within a period of twen- 
 ty-four hours. 
 
 The eyes of King Humbert and his ministers 
 have been opened, as they never were before, 
 to the true state of affairs among the poor of 
 Naples, and the result may be the opening out 
 of new streets through the four sections into 
 which the fresh air of the bay and the purify- 
 ing rays of the sun may enter freely; and a 
 further result, a new system of drainage, not 
 only for these sections, but for the remaining 
 eight. ' ' It has been well said that efficient quar- 
 antine does protect, but after the germs are once 
 introduced no quarantine regulations will serve 
 — nothing then but local hygienic measures will 
 suffice. Neglect to take precautions cost Japan 
 in 1877-78 many valuable lives and produced 
 much serious disaster. In view of the fact that 
 the past year has seen the dread disease attack- 
 ing one place after another on the Continent, 
 the question becomes an important one: What 
 are we doing as a government to protect our- 
 selves from its ravages? Objections are made

 by some to any inspection of ships coming from 
 infected ports, just as they are made by others 
 to the inspection of buildings and yards. There 
 is almost without exception a disbelief in the 
 local existence of a case of Asiatic cholera. 
 Why persons should be so skeptical as regards 
 the existence of individual casas of this disease 
 and the danger from them is inexplicable on 
 any other ground than that of self-interest. 
 There are persons who are so skeptical as to 
 distrust not only external testimony, but the 
 evidences of their own senses, it is true; but 
 the fear that trade will be interfered with and 
 business decreased if the public mind becomes 
 pre-occupied with the idea of danger from an 
 epidemic, leads many men to treat the matter 
 with culpable skepticism. These are the ones 
 who present manifold obstacles to the prosecu- 
 tion of any measures looking toward the pre- 
 vention of disease; fthey are found on every 
 hand — in our halls of legislation, obstructing 
 the passage of bills for the appropriation of 
 money; as members of committees to wait upon 
 
26 Cholera. 
 
 officials and argue against just sanitary legisla- 
 tion; as members of social and business circles, 
 endeavoring to divert individual minds from 
 the contemplation of facts which would tend 
 to kindle a public sentiment in favor of hygi- 
 enic measures. We find them on school boards, 
 refusing to vote for appropriations for heating, 
 ventilating, and draining the school-houses. 
 We find them as property owners, neglecting 
 to put their buildings into such conditions as 
 will render the occupants safe from zymotic or 
 other diseases. Thinking to protect their own 
 interests, they work against the public weal, 
 and thus do injury to themselves. The appear- 
 ance of cholera the past year in Europe leads 
 to the important question: Shall we have it in 
 this country? The history, as we have seen, 
 makes the answer, it is probable we shall. Men 
 may call it sensationalism to agitate the mat- 
 ter, but with the knowledge we have of former 
 epidemics, and the danger attending neglect of 
 thorough measures to prevent its ingress, it 
 would be wrong not to make an endeavor to

 inform the people how they may protect them- 
 selves from infection. Much has already been 
 done by the general government and the vari- 
 ous state and municipal authorities in the 
 direction of a thorough quarantine and disin- 
 fection of persons and goods arriving in this 
 country from infected ports, but experience 
 teaches that even the most vigorous quaran- 
 tine does not prevent, now and then, a case 
 getting in. What has actually been done in 
 any city, town or village to meet such an 
 emergency % Are there hospitals ready for the 
 reception of patients % If one case occurs, it is 
 the source from which there will arise many, 
 unless active measures are adopted to prevent 
 it. There is a disposition not to report such 
 solitary first cases. Have the necessary 
 arrangements been made for an inspecting 
 corps? Are the details for disinfecting pro- 
 vided for? Are the people thoroughly in- 
 structed as to the measures they must adopt 
 to render the spread of the disease impossible % 
 Are the authorities of cities, towns and villages 
 
28 Choleea. 
 
 taking active measures to cause the removal of 
 all filth and disease-breeding material which is 
 the favorite habitat of the cholera germ \ We 
 say the authorities of towns and villages, be- 
 cause facts prove that in many places there is 
 much more carelessness in regard to drainage 
 and the purity of water-supply in the rural 
 districts than in cities. The experience of the 
 residents in the little village of Plymouth, 
 Penn., is an illustration of this. No attention 
 was paid to the disposition of sewage; the 
 water-supply was left to take care of itself. 
 The number of cases of typhoid fever which 
 resulted has now reached 905. A warning 
 sounds with clarion voice to every town and 
 hamlet, large and small, and it behooves the 
 inhabitants, one and all, as well as the authori- 
 ties, to attend to these matters. The author 
 does not wish to seem an alarmist, neither 
 does he desire to appear sensational. The 
 foregoing questions are simply those which 
 occur to every one who considers carefully the 
 present condition of affairs. These are impor-

 tant matters, and if not already attended to, 
 ought at once to be looked after. One of the 
 great difficulties in any epidemic is the panic 
 that comes upon the people; every one thinks 
 something ought to be done and nobody knows 
 just what to do; to be forearmed is to be cool 
 and collected when the time for action comes. 
 As an illustration of how a panic may be 
 produced, we have only to turn to the record 
 of the epidemic in Quebec in 1832. " On the 
 11th of June of that year it was publicly 
 announced that the malignant, or Asiatic chol- 
 era had appeared at Quebec. On the 12th of 
 the same month, the Board of Health of Mon- 
 treal stated that there was no case of malignant 
 cholera, although several patients had died of 
 the common cholera of the country. On the 
 18th, only six days later, we find reported 
 2,516 cases and 437 deaths, but even this was 
 thought at the time to be below the true esti- 
 mate; the panic was so great that it was impos- 
 sible to keep any accurate account of the 
 numbers that sickened or died."*

 When the accounts of the panic which pre- 
 vailed in the epidemics of 1832 and 1849 are 
 reviewed, the almost brutal interment of the 
 dead and the desertion of friendsTnoted, the 
 prevention of a repetition of such scenes is 
 devoutly to be wished. There are no measures 
 for preventing a panic more effective than the 
 dissemination of such knowledge as will cause 
 individuals to feel that they can, and have, 
 put their persons and premises in such condi- 
 tion as to prevent an attack. 
 
CHAPTER II. 
 
 CHOLERA — ITS CAUSE. 
 
 Just what factors are necessary to produce 
 cholera as it appears in its home in the Delta 
 of the Ganges is unknown; it is now believed 
 to have been pretty conclusively proven that 
 each of the various infectious diseases is due 
 to a distinct specific causative agent, and that 
 this agent is probably a living organism. For 
 a long time this had been suspected; nearly 
 half a century ago the statement was made 
 that certain diseases had their origin in a fer- 
 ment, and when Pasteur demonstrated that 
 various ferments were micro-organisms, the 
 supposition grew into a theory, and, under the 
 investigations of Strauss, Roux, Virchow, 
 Koch, and others, the theory has become an 
 
32 Cholera. 
 
 established fact. The announcement by Koch 
 that the germinal cause of cholera had been 
 discovered by him caused, among scientists, 
 an excitement in proportion to the interest 
 centering in the disease at that time. It was 
 on the 26th of July, 1884:, that he gave to his 
 associates in Berlin the results of his investi- 
 gations of the disease in Egypt, Calcutta and 
 Toulon, and affirmed that a little organism 
 shaped like a comma ( ,), so small as to be seen 
 only with a high power under the microscope, 
 was the essential cause of the terrible pesti- 
 lence. Immediately other investigators took 
 up the search, some confirming and others 
 denying the statement. It is not at all to our 
 purpose to follow the discussion of these sci- 
 entists in detail, nor, indeed, even to indulge 
 in any thing more than a brief sketch of some 
 of the arguments in favor of the theory ad- 
 vanced by Koch. He examined a large number 
 of cases of cholera, and found in each the 
 little comma-bacillus; he did not find the true 
 comma-bacillus in the healthy body, nor in 
 
Its Cause. 33 
 
 cases of disease other than epidemic cholera. 
 Two Swiss physicians, Eietsch and Nicati, in 
 the laboratory of the Pharo Hospital, at Mar- 
 seilles, successfully inoculated a number of 
 guinea-pigs, dogs and rats with cholera mi- 
 crobes, and within two days the guinea-pigs 
 died, after having exhibited the symptoms of 
 cholera as seen in human beings; the dogs died 
 in about four days after inoculation, having 
 exhibited the same symptoms. Koch himself 
 afterward confirmed this experiment. This 
 was a crucial test, and seemed to furnish 
 conclusive proof that the comma-bacillus 
 bore a causative relation to cholera. These 
 experiments are in a line with those to which 
 Bernard refers in his "Introduction to the 
 Study of Experimental Medicine," when he 
 says, "The experiments on animals with dele- 
 terious or noxious substances are very useful 
 and perfectly conclusive for the toxicology 
 and hygiene of man," but to which the anti- 
 vivisectionists so strenuously object, Let us 
 see what conclusions these men drew from 
 
34 Cholera. 
 
 their work. "There is a practical mode of 
 diagnosis in all doubtful cases of cholera; in 
 such cases it would be sufficient to repeat with 
 the contents of the patient's intestine the 
 direct inoculation into the duodenum of the 
 guinea-pig to ascertain whether it was a case 
 of cholera or not. The second conclusion 
 which they drew was a prophylactic one, viz., 
 that the gastric juice and the bile digest the 
 microbes very thoroughly. These two juices 
 are excreted in large quantities during the 
 digestion which follows a meal, so that impure 
 water would be less dangerous when taken 
 with food than when drunk by itself."* Do 
 not these conclusions warrant the means em- 
 ployed \ If true, the experiments upon which 
 they are based may be made to relieve great 
 anxiety or protect from much disaster. The 
 life of a human being is of more value than 
 many guinea-pigs. But to return from our 
 digression; while in India, Koch found a water 
 tank the water in which contained an abundant

 supply of the comma-bacillus, and when an 
 outbreak of cholera occurred it was found that 
 the inhabitants had been, and were, using the 
 water; when the microbe disappeared from the 
 water the disease abated, and in the places 
 where the disease did not exist he did not find 
 any comma-bacillus. These are, in substance, 
 the facts as published in the "London Lancet " 
 for September 20, 1884. They seem to prove 
 that the comma-bacillus is the essential cause 
 of cholera; there is need of confirmation by 
 further experiments before they can take their 
 place among indisputable conclusions, but 
 they are pretty generally regarded as an ex- 
 planation of the origin of cholera in places 
 outside of the locality in which the disease is 
 said to have its home. The older writers on 
 cholera speak of the specific cause as being "a 
 peculiar epidemic influence," and say that 
 various circumstances increase the suscepti- 
 bility of the system to this influence; that 
 others hasten the attack, and still others call 
 into operation a latent tendency to it, and so

 cause its development. However this may be, 
 there certainly are conditions which serve to 
 develop the disease in localities and individuals, 
 as we shall see when we come to consider some 
 of the assisting causes and review some of the 
 measures for its prevention. The theory of an 
 epidemic influence seems to find corroboration, 
 in the opinion of some, in many of the circum- 
 stances occurring during a season of cholera 
 visitation. One of these is that a number of 
 cases of some particular disease occur just pre- 
 vious to an outbreak of cholera; another, that 
 so many are stricken down at the same time in 
 different places who apparently have had no 
 communication with each other, nor with any 
 infected district; still another, that ships sail- 
 ing upon the ocean have suddenly developed 
 on board cases of the disease. As regards the 
 first, it is not well proven; it is a fact that 
 during an epidemic of cholera there are numer- 
 ous cases of intestinal disturbance, but these 
 may be accounted for on the supposition that 
 an advanced guard, so to speak, of the epi-

 demic gains an entrance to the body, but, not 
 finding there the conditions under which it 
 thrives, serves only as a slight irritant and 
 then passes away; in regard to the second and 
 third, the germ theory of disease accounts for 
 them much more satisfactorily than any other. 
 There are certain well-established facts in con- 
 nection with the epidemics that have occurred 
 heretofore which substantiate these assertions. 
 First, it has frequently been observed that the 
 dejecta from persons suffering with simple 
 intestinal flux have produced cholera: second, 
 as has already been mentioned, it, in the ma- 
 jority of cases, starts from India, although Dr. 
 Elisha Harris says: " Cholera has prevailed 
 extensively in the United States during eight 
 out of the forty-one years since its first appear- 
 ance on this continent. But in only four out 
 of the eight years, as we have reason to con- 
 clude, was this pestilence freshly introduced 
 into the United States from Europe. The new 
 importations of the exotic germinal cause were 
 abundantly witnessed in the years 1832, 1848- 
 
38 Cholera. 
 
 49, 1854, 1865-66."* It follows the lines of 
 travel pursued by armies, caravans, pilgrims 
 and transports through and over the water- 
 ways of Europe. It moves with the merchant 
 marine to this continent, where we can trace it 
 over all our routes of travel, along the canals, 
 railroads, rivers, lakes, across the plains; every- 
 where man goes, it goes. Man is the chief car- 
 rier of the disease. We notice, too, from the 
 history, that it extends most rapidly where 
 there is the greatest aggregation of men, and 
 that among the class of people with whom 
 squalor is a constant condition, whose houses 
 are dirty, whose persons are unclean, and 
 whose surroundings are filthy, the disease runs 
 riot during an epidemic. These circumstances 
 lead to the conclusion that there is a specific 
 cause and man is the chosen vehicle for the 
 transmission of that cause. We observe, too, 
 that in a city attacked by the disease there is 
 sometimes a distinct line drawn between the 
 infected and the uninfected district; one side

 of a street will be affected, the other will 
 escape; the upper story of a house will be free, 
 while the lower may have two or more cases, 
 which would tend to prove that the cause is 
 not an epidemic influence, but a distinct germ, 
 which, finding in certain restricted localities 
 the necessary conditions for its growth, devel- 
 ops into virulence. We have seen that in 
 Mecca when the city was crowded with pilgrims 
 who drank of water made foul by centuries of 
 'unsanitary practices, and polluted by them- 
 selves, there was a terrible re- enforcement of 
 the disease. Similar occurrences took place in 
 India, China and Japan before the systems of 
 sewerage now in operation were completed, 
 and with the removal, by this new sewerage 
 system, of the contaminating material from the 
 water supply, the violence of the epidemics has 
 been very much diminished. When we con- 
 sider that in these places, with the exception 
 perhaps of a portion of India, cholera does not 
 exist all the time, but the water is drunk con- 
 stantly, the question at once arises : Why is 
 
 4 
 
40 Cholera. 
 
 this so ? For answer we look to the reports of 
 Commissions appointed by several governments 
 to investigate this very point, and we find that 
 in probably every case the disease was brought 
 by some person or persons coming from an 
 infected district, and the germs of this disease 
 gaining entrance to this polluted water, found 
 there the very best conditions for their rapid 
 development. Enough has been said to indi- 
 cate the reasons why cholera is supposed to 
 have its origin in an organism. That the 
 comma-bacillus is this organism is stoutly 
 denied by many investigators, and the reasons 
 given for this opinion are certainly entitled to 
 consideration. Some of these men admit that 
 the comma-bacillus, while in and of itself 
 harmless, yet does excrete a virus, under cer- 
 tain conditions, which produces cholera; but, 
 as has already been said, it is not our purpose 
 to follow all the arguments pro and con; those 
 who desire to do so can find them fully set 
 forth in the reports of the various cholera com- 
 missions, as published for the several Boards 
 of Health. 
 
CHAPTER III. 
 
 CHOLERA — ITS PROPAGATION. 
 
 The fact admitted that the origin of cholera 
 is a germ, it will be profitable for us to con- 
 sider, before studying measures for the pre- 
 vention of an epidemic, some of the assisting 
 causes, or, in other words, some of the means 
 by which the germ is propagated when once 
 introduced. It is a self-evident proposition 
 that to keep it out is the best thing to do, but 
 this cannot always be done, and if those con- 
 ditions which aid its development are under- 
 stood, preventive measures will be plainly indi- 
 cated. There are those who denounce quar- 
 antine as barbarous and, at best, ineffectual, 
 and consequently useless. While there are 
 many objectionable features connected with 
 
42 Cholera. 
 
 systems of quarantine, instances are not want- 
 ing which demonstrate its value and show the 
 evil result of its abandonment. When Den- 
 mark, which had been frequently exposed to 
 the danger of cholera infection from other 
 nations, but had always escaped through the 
 strict quarantine she maintained, for the first 
 time removed this, an epidemic occurred in 
 the country, in which there were 7,000 cases 
 with 4,000 deaths. The quarantine was then 
 re-established, and there has been no more 
 cholera there up to the present time. The 
 same thing was true in regard to Greece. Al- 
 though quarantine may not be competent to 
 prevent the ingress of every case of infectious 
 disease, it is a safeguard of inestimable value 
 at ports of entry, and its maintenance in an 
 efficient manner is a matter upon which inland 
 towns, especially those situated upon the great 
 water-ways and routes of travel, have a right 
 to express an "opinion, and a right, also, to 
 expect that their opinion will be regarded. 
 Among the assisting causes of cholera, we may

 43 
 
 mention, first, that of fear. It is well known 
 that there is no moral influence which produces 
 so depressing an effect on the system as fear. 
 It has been clearly proved that the most vigor- 
 ous of men, even in the most perfect health, 
 may be frightened to death. Instances were 
 not wanting during the war of the Rebellion 
 where soldiers were so overcome by fear from 
 an impending battle as to be thrown into a vio- 
 lent intestinal flux, which rapidly reduced 
 them. If we only look at a frightened person, 
 we see that he presents almost the first symp- 
 toms of cholera; the blood retreats from the 
 surface to the central organs of the body, leav- 
 ing the face pale, the hands cold, and the pulse 
 feeble; indulged in to any extent, it reduces 
 the resisting power of the system, and the per- 
 son falls a victim to a disease which might not 
 have attacked him at all, or have proved so 
 light as to have produced no serious conse- 
 quences. Furthermore, it interferes with the 
 discharge of those duties upon the faithful 
 discharge of which the safety of the person, 
 
44 Cholera. 
 
 and perhaps the household, depends. It serves 
 also to spread the disease; a person dreads an 
 attack, and, to avoid it, leaves the place where 
 the epidemic is prevailing ; with him go the 
 germs of the disease, they find lodgement in the 
 material favorable for their development, and 
 in a little time cholera appears in that place. 
 An illustration of this is found in a case occur- 
 ring in the little village of Omergues, in France. 
 The place is a small, closely built mountain 
 hamlet, where few ideas of cleanliness or sani- 
 tary prudence prevail. A servant in Marseilles 
 left her employer and went to her home in this 
 little village, taking with her the fatal germ. 
 She and two of her family died, a panic seized 
 upon the little community, and before the dis- 
 ease could be checked twenty-five of the inhabi- 
 tants had died. Another assisting cause is 
 found in impaired health. This term is made 
 to include every condition that tends to weaken 
 the vital energies, whether it be exhaustion 
 from overexertion, either physical or mental; 
 want of sufficient nourishment; derangement

 of the digestive organs by excesses in eating or 
 drinking; debility from exposure or excesses 
 of any kind; the existence of any constitu- 
 tional disease or the convalescence from sick- 
 ness; by reducing the vital power they bring 
 the system within the influence of the epidemic 
 cause. Bad drainage is one of the chief allies 
 of cholera. In cities it acts to pollute the 
 atmosphere of dwellings, and, when accom- 
 panied by poor ventilation, surcharges the air 
 with noxious gases, and the vital functions are 
 so materially interfered with as to produce a 
 condition of the system which renders it very 
 susceptible to the epidemic cause of the disease. 
 In the country it leads to the deposition upon 
 the surface of the ground of a mass of decaying 
 matter, which serves as a breeding place for 
 the cholera germ and causes the pollution of 
 wells, cisterns and other sources of water sup- 
 ply. In many places the drain is nothing more 
 than a ditch, in which lies a mass of putrefying 
 matter exposed to the rays of the sun and 
 exhaling poison along its whole length; in 
 
46 Choleea. 
 
 other cases it is covered, but having been con- 
 structed of wood, this decays and permits the 
 contents of the drain to escape and filter 
 through the soil into the cellar or well. This 
 leads directly to the consideration of another 
 assisting cause, and that is filth. Decaying 
 vegetable and animal matter in or around a 
 dwelling is in violation of one of the oldest 
 and most important sanitary principles. Such 
 material, if not the breeder, is a harborer of 
 the germs of very many diseases, and of none 
 more so than of cholera. In the history of 
 every epidemic we find those places low-lying, 
 damp and dirty invariably attacked. The dis- 
 ease is not always confined to them, it is true, 
 for causes may be operative to make it appear in 
 places scrupulously clean, but places abound- 
 ing in filth are never exempt. The lower por- 
 tions of large cities, where the streets are nar- 
 row and buildings high, so that the sun can 
 never reach them, where all the refuse from 
 the houses, it would seem, is thrown into the 
 roadway, creating such a stench that one almost

 fears to breathe while passing through, where 
 women and children vie with each other in 
 seeing which can present the most wretched 
 appearance, where the homes (?) are the acme 
 of filth and misery; these portions are the first 
 to be attacked in an epidemic, and the foci 
 from which radiate thousands of disease germs. 
 Filth is not confined to these portions of the 
 town, however; oftentimes in what would be 
 called well-regulated families there are found 
 vessels filled with decaying garbage, stationary 
 tubs half filled with dirty wash- water, areas in 
 which lie rotting and rusting all sorts of things, 
 the accumulation of months; cellars in the dark 
 corners of which are vegetables long since 
 dead; streets, alleys and yards in such condi- 
 tions of neglect that the only wonder is that 
 any one can be well. The cholera persistently 
 hunts out such places, and lurks there until it 
 has gathered strength sufficient to attack and 
 destroy whole families. In many places in the 
 country the filthy habit prevails of emptying 
 all the refuse from the kitchen, wash-water, 
 
48 Cholera. 
 
 and chamber vessels upon the ground just out- 
 side the house, and for the space of three or 
 four yards square the ground is sodden and 
 slimy. Until the people can be made to change 
 this condition of affairs, zymotic diseases will 
 flourish and epidemics will find plenty of food. 
 The most powerful of all the causes which 
 assist in propagating cholera is drinking water 
 polluted in some way. We have seen that in 
 Egypt and India pilgrims use for drinking the 
 same water they have used for bathing and 
 washing their clothing, and we have seen how 
 terribly they suffered with cholera. There is 
 abundant evidence, amounting almost to a 
 demonstration, that polluted drinking water 
 plays the most important part in disseminating 
 cholera. John Marshall, of the University 
 College, England, has furnished, in a commit- 
 tee report, the most convincing evidence of this; 
 (this is the celebrated Broadstreet pump case). 
 " In Rotterdam, during an epidemic of cholera, 
 the introductioD of pure water immediately 
 reduced the mortality to one-half. Dr. Auc- 
 
Its Pkopagation. 49 
 
 land relates, as quoted by Dr. Parkes, that two 
 jails were near each other; the inmates of the 
 one suffered, those of the other did not; the 
 water was impure in the one case from drain- 
 age, pure in the other. The jail with bad water 
 having got a fresh supply, the cholera did not 
 appear there in the next epidemic. In Haar- 
 lem, Holland, cholera prevailed with great 
 intensity in 1849. In 1866 it returned and 
 again prevailed as severely in all parts of the 
 town, except one; that part entirely exempted 
 in the second epidemic was inhabited by bleach- 
 ers, who, between 1849 and 1866, had obtained 
 a fresh source of pure water. 
 
 "Prof. Foerster has shown that five towns 
 of Silesia (of 5,000 to 12,000 inhabitants) are 
 entirely free from cholera, which never spreads, 
 even when introduced. The only common con- 
 dition is a water supply which cannot be con- 
 taminated. In Glogan half the water is from 
 a distance and half from wells; those using the 
 former remain free; those using the latter are 
 attacked. Dantzic and Konigsberg formerly

 suffered equally; Dantzic having a new water 
 supply, does not suffer; Konigsberg, with its 
 original supply, continues to suffer. In Berlin, 
 in 1866, cholera prevailed much more in the 
 houses supplied with bad water than in houses 
 su pplied with good water. ' ' * We have already 
 mentioned that in India the introduction of 
 a sewerage system relieved the water supply 
 of much impurity, and in consequence the 
 violence of epidemics is very materially dimin- 
 ished. Impure drinking water is obtained in 
 many of our cities, from several sources. 
 Wells located in thickly populated districts 
 receive more or less of the surface drainage 
 from filthy streets, and much of the water in 
 them comes through soil saturated with pollu- 
 tion of various kinds; it is said that in the city 
 of St. Louis there are 7,000 such wells sunk in 
 the various streets, alleys, courts and yards of 
 tenement and other houses, and surrounded by 
 vaults, stables, cesspools and sewers; in other 
 cities the same is true, though not perhaps to

 so great an extent. Elvers and streams, the 
 banks of which are thickly studded with vil- 
 lages, towns, populous cities, manufacturing, 
 dyeing and cleansing, and refining establish- 
 ments, are taken for the source of a water sup- 
 ply; the filthy stuff flowing in them is pumped 
 into reservoirs, distributed throughout a city, 
 and the inhabitants compelled not only to 
 drink it, but to pay a good round sum for the 
 privilege (?) of risking poisonous infection with 
 every draught they imbibe. The citizens are 
 told by those in whose power they are that 
 water contaminated by the sewage of a city of 
 50,000 inhabitants will purify itself in a flow of 
 a very few miles, whereas instances without 
 number are on record that such is not the case. 
 We will not occupy space to cite cases, but w T e 
 cannot prevent the mind of the reader reverting 
 to the fatal epidemic of typhoid fever, not yet 
 over, in Plymouth, Penn., where upwards of 
 900 persons have suffered from the effects pro- 
 duced by the dejecta of one person having been 
 introduced to the source of water supply at a 
 
52 Cholera. 
 
 distance of several miles above its point of dis- 
 tribution. Such evidence points out the dan- 
 ger at all times lying in the use of water for 
 drinking purposes which comes from a source 
 liable to pollution. At the present time it has 
 an added significance; not that foul water will, 
 per se, produce cholera ; no amount of bad 
 water will do that ; the germ must be im- 
 planted. Fear, poor health, bad drainage, 
 want, squalor, filthy surroundings — none of 
 these things will produce cholera, but the dis- 
 ease flourishes amid such surroundings. No 
 soil, however rich, will produce a crop if the 
 seed be wanting, of which proposition the con- 
 verse is also true — no seed will produce a crop if 
 the soil is not good. To gather up, then, the re- 
 flections in this chapter, we may say that the 
 present position of the best authorities, which 
 meets facts as observed, and may be accepted 
 as correct, is as follows : Cholera is the result 
 of the development of a germ; it is conveyed 
 by individuals chiefly, and by the articles 
 soiled by the dejecta of cholera-infected per-

 sons; "its poison is contained in, and propa- 
 gated by, the discharges from the bowels of 
 those infected, which, finding access to drink- 
 ing water, or resting upon food, gains entrance 
 to the digestive tract of others. It is not cer- 
 tain that in a heavily charged atmosphere the 
 poison may not be swallowed with the air, but 
 the infection mnst take place through the ali- 
 mentary canal, and in this very limited sense 
 alone can cholera be spoken of as i contagious,' 
 thus probably resembling typhoid fever. In 
 other words, an individual who could avoid 
 swallowing the poison, might safely associate 
 with cholera patients, and the digestive func- 
 tions being quite healthy, he would probably 
 escape, even if he swallowed a moderate dose."*

CHAPTER IV. 
 
 CHOLERA — ITS PREVENTION. 
 
 The means by which cholera may be pre- 
 vented have already been indicated by the 
 explanation of its cause and the description of 
 the ways in which it is diffused. Its habits, 
 and the factors in its cause and spread, being 
 so well understood, we are warranted in be- 
 lieving that this pestilential destroyer may be 
 successfully resisted, and its material means 
 of propagation be completely controlled. Sci- 
 entists may differ as to the exact form of its 
 specific germ, physicians may vary in their 
 opinions as to some of the facts concerning the 
 various forms of the epidemic and the most 
 effective treatment, but upon the essential 
 points— sanitary measures as preventive means 
 
Its Prevention. 55 
 
 — there is as much, certainty as there is upon 
 similar facts in the causation and prevention of 
 any other epidemic disease. The fact that in 
 Bombay, Madras, Calcutta and other places 
 where, in former times, the disease made such 
 terrible havoc, methods have been adopted by 
 which the pestilence is shorn of half its terrors, 
 indicates very clearly that similar methods 
 pursued in a country where the disease is only 
 epidemic, where it does not naturally grow, 
 would be efficient to destroy it altogether. 
 "When considering the causes of cholera, we 
 took occasion briefly to allude to some views 
 upon the subject of quarantine, and will, at 
 this time, only add that in the enforcement of 
 strict quarantine regulations it is possible, 
 unless great consideration is shown, to work 
 much injury to those whose persons or goods 
 are subjected to them; furthermore, there is 
 apt to be so much reliance placed upon such 
 regulations as to lead to carelessness on the 
 part of those presumed to be protected by them, 
 sanitary precautions are neglected, and they 
 
 5

 are rudely awakened from their dream of fan- 
 cied security to find the visitor upon them and 
 their house not ready to receive him. The 
 fact that cholera is transmissible is beyond 
 question; so also is the fact that it does not 
 fatally attack all the individuals exposed to its 
 influence. A well-regulated life and good 
 hygienic conditions are almost certain guaran- 
 ties against its action; it rages by preference in 
 unhealthy localities, among populations weak- 
 ened by misery and among individuals whose 
 powers of resistance are undermined by disease 
 or excess. All these circumstances are, to a 
 large extent, under the control of individuals, 
 and, in so far as they are, it is for each one to 
 decide for himself whether or not he will be 
 attacked by the disease. We have seen it is 
 not contagious, in the wide sense of the word, 
 and so there is no need for that morbid fear 
 which only renders its subject the more liable 
 to be attacked; if, however, there shall be a 
 wholesome dread which will lead to the en- 
 forcement of strict sanitary rules in every 
 
Its Pkevention. 57 
 
 household, much good will be accomplished. 
 Observation has shown that cholera is a pesti- 
 lence which is nourished in a locality where 
 there is stagnant water and marshy ground, 
 and that such places when visited by it become 
 foci for the further distribution of it. It be- 
 comes, then, a matter of the highest impor- 
 tance that such places be reclaimed from their 
 unsanitary conditions. An hour' s ride through 
 almost any city will bring to view large areas 
 covered with stagnant water or reeking with the 
 decomposition of material left after the water 
 has evaporated. The local boards of health en- 
 deavor to reclaim such places, but frequently 
 they are met by the most violent opposition 
 from those who should be foremost in promot- 
 ing the public welfare. It is the duty of the 
 authorities to co-operate with the board of 
 health in these matters and to see that such 
 places are put in a safe condition; if the doing 
 so works an injury to individuals, liberal ap- 
 propriation should be made to compensate for 
 such injury. Landlords and owners of houses 
 
58 Choleea. 
 
 in towns and cities should see to it that the 
 drains in their houses are in proper condition, 
 so that the atmosphere may not be contami- 
 nated with emanations from sewers, sinks and 
 cesspools. Occupants of houses should make 
 sure that there is nothing in or around the 
 house, in cellars, areas, back-yards, alleys or 
 out-buildings, which, by its decomposition, 
 shall pollute the air. The rich suffer equally 
 with the poor when surrounded with a pol- 
 luted atmosphere, so that it becomes a matter 
 of general concern. In the country, out-houses, 
 pig-pens and chicken-houses should be kept 
 clean and privy vaults disinfected daily. A 
 foul air, at all times, undermines health, but 
 when an epidemic comes it renders the mor- 
 tality very much greater than it otherwise 
 would be. The medical officer of the Privy 
 Council of England, as quoted by the late Dr. 
 Harris in his report already referred to, says : 
 "The specific migrating power of cholera, 
 whatever its nature, has the faculty of infect- 
 ing districts, in a manner detrimental to life,

 only when the atmosphere is fraught with cer- 
 tain products susceptible, under its influence, 
 of undergoing poisonous transformations. 
 Through the unpolluted atmosphere of cleanly 
 districts it migrates without a blow. That 
 which it can kindle into poison is not there. "* 
 " There is a small colony of Moravians at a 
 place called Sarepta, situated in the bend of 
 the river, which has been noted by travelers 
 for its neatness and industry. Dr. Verollot 
 says the cholera itself seems to respect this 
 sacred spot, passing by both in 1830 and 1847 
 without inflicting on it the least injury." The 
 sanitary condition of the place is the most 
 important thing to be attended to. Local 
 boards of health can do much of this, but not 
 all; the citizens themselves must be willing to 
 co-operate with them. There ought to be a 
 strong public sentiment in regard to the mat- 
 ter, so that when a question of sanitation 
 comes up for consideration it will have the 
 attention and support of the public; if this was

 the case, there would be much less cause for 
 complaint that unsanitary conditions remain 
 unremedied. Too often the people, as well as 
 the authorities, when notified of such evils by- 
 health officers, receive the information with an 
 indifference and apathy, if not a spirit of oppo- 
 sition, that is quite discouraging. We expect 
 some opposition from the poorer classes and 
 the uninformed whenever the enforcement of 
 sanitary rules, such as vaccination, isolation, 
 disinfection, drainage or ventilation, is at- 
 tempted, but from the better class it ought not 
 to be so. With more effort on the part of 
 those who know and realize the importance of 
 these matters, information might be furnished 
 that would prevent all annoyance. The intro- 
 duction of the study of hygiene, the laws of 
 health and the elementary principles of sani- 
 tary science into our public schools; a sermon 
 preached once in a while upon the subject by 
 clergymen, especially those having the spiritual 
 oversight of congregations composed largely of 
 a class of people who, if appearances are any

 indication, are either wofully ignorant or else 
 care but very little for personal cleanliness or 
 the purity of their surroundings, would ma- 
 terially assist in this result. Certainly the 
 bearing of this subject may be shown to be 
 very direct upon those higher principles which 
 clergymen are selected to teach and exemplify. 
 A law enacted which would be something more 
 than a "dummy," whereby persons could be 
 punished for not exercising the proper care in 
 such matters, or the execution of such laws as 
 already exist, would furnish some wholesome 
 examples, now and then, by way of a reminder 
 to the willfully negligent. Judge Dixon, of 
 New Jersey, in a recent charge to the grand 
 jury at Paterson, said: "If a man, conscious 
 that he carries about with him the germs of a 
 contagious disease, recklessly exposes the 
 health and lives of others, he is a public nui- 
 sance and a criminal, and may be held answera- 
 ble for the results of his conduct. If death 
 occurs through his recklessness, he may be 
 indicted for manslaughter. The man may be 
 
 : 
 
62 Cholera. 
 
 indicted also for spreading the disease by con- 
 scious exposure of others thereto, by his pres- 
 ence in public places, such as on the streets, 
 in halls, etc. He might be indicted for endan- 
 gering the public health in this way, even if 
 no consequences had followed. The law pro- 
 vides some penalty for such olfenses against 
 the public safety."* The man who maintains 
 a nuisance is amenable to the law if he does 
 not abate it when notified to do so, because he 
 endangers the public safety. The man who 
 maintains his premises in an unsanitary condi- 
 tion endangers the public safety equally with 
 those mentioned, and ought to be punished as 
 well. The prominent part an impure water 
 supply plays in the spread of cholera has been 
 dwelt upon at some length in the chapter on 
 "Propagation," audits importance requires 
 that emphasis should here be laid upon its re- 
 moval. Impure drinking water not only serves 
 as the medium for the transmission of the 
 cholera germ during an epidemic, but it ever

 threatens the health and life of the persons 
 using it. Wells in localities rendering the pol- 
 lution of their waters probable should be so 
 strictly guarded, and if need be closed, as to 
 render it impossible for persons to obtain water 
 from them for drinking purposes, and boards 
 of water commissioners ought to be compelled, 
 if necessary, to protect the sources of their 
 water supply from pollution. This would be 
 impossible in the case of a supply taken from 
 large rivers or from streams upon whose banks 
 there is either much population or manufac- 
 turing establishments. These are inevitable 
 sources of pollution, the possibility of remov- 
 ing which not existing, such sources should 
 not be taken for a water supply. 
 
 Thus far we have considered preventive or 
 precautionary measures as relating to localities 
 not already attacked by an epidemic disease. 
 We have seen that thorough systems of drain- 
 age and sewerage, removal of filth and offal of 
 every kind, good pure air and wholesome 
 water, will do very much towards protecting a

 community from an attack, but all these pre- 
 cautions may fail to prevent some cases gaining 
 access to a city or town. It will be well, there- 
 fore, to review some of the measures necessary 
 to prevent the spread of cholera, should cases 
 of the disease actually present themselves. 
 One of the most important of these is personal 
 hygiene. Cleanliness of person and clothing — 
 the free use of soap and water — has been the 
 means of saving the health of many a person. 
 What has been said of clean streets, clean air 
 and clean water is just as true of clean persons; 
 the cholera germ abhors them. Moderation in 
 eating and drinking is also important, for, as 
 we have seen, it is possible for the fluid of a 
 healthy stomach to digest, and so destroy, the 
 virus of cholera; not so with that of a stomach 
 wearied with the labor necessary to dispose of 
 an inordinate amount or variety of food, or 
 wrought up almost to a condition of mutiny by 
 floods of alcoholic or brewed liquor having 
 been poured into it. As when a person is 
 fatigued to excess by mental or physical toil 
 
Its Pkevention. 65 
 
 he readily succumbs to the malign influence 
 producing pneumonia, so when the digestive 
 organs are overtaxed the alimentary canal is 
 in poor condition to resist the invasion of the 
 cholera germ. Plain, wholesome, nutritious 
 food, in sufficient quantity, with no excess in 
 the use of tobacco and liquor, fortify t^e sys- 
 tem under almost all conditions; in times, how- 
 ever, when cholera is present in a place, some 
 extra precautions will be needful. Heat de- 
 stroys the cholera germ; hence no food should 
 be partaken of unless thoroughly cooked. 
 Such articles as cannot be subjected to this 
 process should, in a season of cholera visita- 
 tion, be dispensed with. This does not apply 
 to such vegetables and fruits as can be peeled 
 or pared; these articles having been cleansed 
 and the rind removed, may be eaten, provided 
 they are fresh and ripe, and not over-ripe. 
 The reason why fruit oftentimes provokes dis- 
 turbance when eaten is because it is either 
 unripe, over-ripe, or because it has been kept 
 so long as to have allowed the process of decay 
 
66 Cholera. 
 
 to begin. The possibility of the transmission of 
 infectious and epidemic diseases through the 
 agency of cow' s milk is established beyond a 
 question. Nearly fifteen years ago an epidemic 
 of typhoid fever raged in a little town, and 
 most careful investigation was made to dis- 
 cover, if possible, the cause of it; finally sus- 
 picion pointed to the milk supply, and it was 
 the pronounced opinion that the virus was dis- 
 seminated through that medium. Since then 
 much attention has been given to this source 
 of transmission, and a large number of epidem- 
 ics have been traced indubitably to milk which 
 had in some way become contaminated by the 
 virus of an infectious disease. " Dr. Thurs- 
 field, an English Medical officer of health, who 
 has investigated the subject of milk epidemics 
 very carefully, proposes certain precautions 
 which he considers effectual in preventing 
 these outbreaks of disease. The responsibility 
 is divided between the consumer and the sani- 
 tary authorities. He urges upon the consumer 
 the precaution of boiling all milk. There is a 
 
Its Prevention. 67 
 
 prejudice against this practice, but it ought to 
 give way if it be true that ' to boil milk may, 
 for practical purposes, be said to confer immu- 
 nity from infection conveyed by it.' The milk 
 shop of the retailer and the dairy of the whole- 
 sale purveyor should be placed under the 
 strict control of the sanitary authorities, which 
 should be clothed with power to make proper 
 regulations and to enforce them by the aid of 
 efficient inspectors."* Just how the milk be- 
 comes infected it may be difficult to say in 
 every case; the vessels in which it is contained 
 may become contaminated, or the water with 
 which it is sometimes adulterated may be the 
 bearer of the specific germ; but that it is, at 
 times, a medium for the dissemination of 
 disease germs, is beyond question. And yet 
 it is impossible to detect the virus in 
 most cases by any form of investigation or 
 analysis; hence the force of the remarks just 
 quoted. There should be strict sanitary care 
 (and official inspection if necessary) of all

68 Cholera. 
 
 dairies and milk shops, and the milk should 
 be boiled before being used by the consumer. 
 What has been said in regard to milk is pre- 
 eminently true in regard to water. No water 
 should be used for drinking or culinary pur- 
 poses that has not been boiled and carefully 
 protected from the air. By the process of 
 boiling, the germ, if the water contains any, 
 is killed; but if the water is then left to cool in 
 open vessels it is liable to re-contamination; 
 it should therefore be bottled before being put 
 away to cool. Boiling not only kills the dis- 
 ease germ, but it u kills" the water too. Any 
 one who has tasted boiled water knows how 
 insipid it is. This flatness may be removed to 
 some extent in several ways; a few tea leaves 
 may be put into each bottle just before the 
 boiling water is put in; this will not make tea 
 in the ordinary sense of the word, but it will 
 materially relieve the insipidity. A little 
 lemon juice added to the water improves the 
 taste very much, and also serves the purpose 
 of supplying to the system a very useful sub- 
 
Its Prevention. 69 
 
 stance in cholera times. It has been shown that 
 the cholera germ can only live in an alkaline 
 solution, that a neutral solution is unfavorable 
 to its rapid development, and that a solution 
 in which there is the least trace of an acid is 
 fatal to it in a very short time. This would 
 suggest the propriety of drinking lemonade 
 and other acidulated drinks, in moderation. 
 Great caution should be exercised in cholera 
 times in the use of lettuce, chopped cabbage 
 and other vegetables which it is customary to 
 eat without cooking; the vinegar usually used 
 with them serves somewhat as a protection, 
 but should always be put on and allowed to 
 stand for a few minutes before the oil, if any 
 used, is put on. Care should be exercised, 
 too, as regards the use of ice. While ice cut 
 in the winter, preceding an epidemic, would 
 not be likely to contain the germ, it neverthe- 
 less may become the medium for its transmis- 
 sion; it presents one condition favorable to its 
 development, that is moisture. Freezing does 
 not kill the germ, it only arrests its growth; 
 
70 Cholera. 
 
 finding a lodgment on the ice, and so an 
 entrance to the refrigerator, this microscopic 
 fiend wonld be ready at the first opportunity 
 to pass from the ice to the meat, vegetables, 
 milk, or any other food that might be placed 
 near it. The best modern refrigerators have a 
 distinct compartment for the ice, entirely sep- 
 arate from those in which the articles of food 
 are kept; where such are used precaution is 
 only necessary when the ice is taken from 
 them, and put in the water, or on the butfcer, 
 or in any other way is brought in contact with 
 the food. It will be seen from the foregoing 
 remarks that the main object to be kept in 
 view is to prevent the cholera germ from enter- 
 ing the alimentary canal. Dr. Simmons, refer- 
 ence to whose report on the cholera epidemic 
 in China and Japan has been made several 
 times in the preceding pages, has passed 
 through a number of cholera epidemics in 
 Europe and Asia, and seems to fear the disease 
 no more than chicken-pox. Neither he nor 
 his attendants have ever suffered an attack, 
 
Its Prevention. 71 
 
 and he attributes their immunity in very great 
 measure to the adoption of such precautions as 
 those already mentioned. That there may be 
 still further safety provided, disinfection will 
 necessarily be resorted to — disinfection of 
 vaults, cesspools, sewers, drains, waste-pipes, 
 water-closets, cellars and all parts of the house 
 where possibly there might be material or 
 place in which the disease germ could thrive. 
 In case a person is attacked with the disease, 
 thorough disinfection of the room, the material 
 evacuated from the bowels, and the clothing 
 soiled by these, or in any other way by the pa- 
 tient, will be absolu tely essential. Of the various 
 disinfectants we shall speak more particularly 
 in another chapter. Cholera comes on insidi- 
 ously and runs its course with great rapidity. 
 In this disease the expression, " While there 
 is life there is hope," is as true as in any 
 other, but all authorities are agreed that the 
 golden opportunity for curing the patient is 
 during the preliminary diarrhoea. It is the 
 more important to remember this, as the 
 
 6 
 
72 Cholera. 
 
 bowel trouble is attended with little or no 
 pain; there is an inclination to go to the closet 
 somewhat more frequently than usual, but, 
 there being no pain — nothing but a slight feel- 
 ing of weariness — suspicion is not aroused 
 until the patient is suddenly prostrated; dis- 
 charge follows discharge, vomiting sets in, 
 violent cramps seize the poor victim, a death- 
 like pallor overspreads the face and form, the 
 eyes are surrounded by dark blue circles, a 
 cold, clammy, but very profuse perspiration 
 bathes the skin, the patient grows weaker and 
 weaker, and soon enters the stage of collapse; 
 even to this time the mind has remained per- 
 fectly clear, but now its torch flickers and 
 goes out as the spirit takes its flight from the 
 tortured body. The disease is of too serious a 
 nature, runs too rapid a course to warrant me 
 in giving, in this place, any methods for home 
 treatment; I shall offer in their place one or 
 two cautionary suggestions. On the appear- 
 ance of the slightest diarrhoea in a cholera 
 season, see your family physician; do not wait

 to take a little medicine, laxative or astringent, 
 as yonr judgment may decide, thinking that 
 on the morrow, if you are not better, you will 
 see the doctor; remember the golden oppor- 
 tunity is just at this time. Beware of adver- 
 tised "Sure Cures for Cholera;" "there is 
 death in the pot." Your trusted family physi- 
 cian is the one to consult, and his prescription 
 will be the safest for you to follow. Having 
 thus briefly stated some of the more prominent 
 facts in regard to cholera, we come now to con- 
 sider a little more in detail some of the things 
 which make for better health of communities 
 and individuals. 
 
CHAPTER V. 
 
 THE HYGIENE OF FOOD AND DRINK. 
 
 When the preventable causes of disease are 
 considered, especial attention mnst be paid to 
 the purity and wholesomeness of those articles 
 which constitute our daily food and drink, and 
 this attention, which is at all times a duty, is 
 more particularly demanded during seasons 
 when sickness is unusually prevalent or epi- 
 demics of specific diseases are anticipated. The 
 possible introduction, ere long, of cholera into 
 the United States, and the probable spread of 
 the disease if introduced, renders it incumbent 
 upon us to set our houses in order and to take 
 more than ordinary precautions for the preser- 
 vation of health. A few remarks, therefore, 
 upon food and its adulterations and water and 
 
The Hygiene of Food and Deink. 75 
 
 its impurities will probably be considered not 
 out of place in this connection. 
 
 Our foods, in the ordinary sense of the 
 word, are derived from the animal and vege- 
 table kingdoms exclusively. From the former 
 we chiefly obtain those substances which 
 build up our tissues and repair the constant 
 waste of the body, and from the latter most 
 largely those compounds which by their 
 oxidation develop animal heat and force. 
 Meat, since in some form it makes up a con- 
 siderable portion of the diet of most adults 
 and is most important as a tissue former, 
 may well receive attention first. It is fortu- 
 nately, as a rule, easy to obtain wholesome 
 meat in most sections of this country. Fresh 
 meat properly cooked is more digestible and 
 nutritious than that which has been salted or 
 smoked. If care be taken during hot weather 
 that meat be not tainted from incipient putre- 
 faction, no especial precautions need be exer- 
 cised in the use of ordinary butcher's meat. 
 Beef tea, as usually made, has little or no food 
 
76 Cholera. 
 
 value, and is more of a stimulant than a nu- 
 trient. The possible presence of trichinae in 
 pork is to be borne in mind, and it should be 
 remembered that salting or smoking does not 
 necessarily destroy the parasite, but that a 
 sufficiently high temperature does, so that no 
 risk whatever attends the use of well-cooked 
 pork in any form. Certain articles manufac- 
 tured on a large scale from various odds and 
 ends, like head-cheese and sausages, are often 
 made from diseased, decayed or otherwise un- 
 wholesome meat, and should be used with 
 caution. A specific poison, the exact nature 
 of which is not well understood, is sometimes 
 developed in such foods which is capable of 
 giving rise to the most distressing illness. Fish 
 is, when fresh and not in too large quantity, a 
 generally wholesome food, but if it has changed 
 color or has an unpleasant odor, it is unfit for 
 consumption. Many kinds of meat and fish 
 are now put up in hermetically-sealed tins, and 
 while a prejudice exists on the part of some 
 against their use, this prejudice is not, in the 
 
The Hygiene of Food and Dkine:. 77 
 
 main, well founded. Many cases of illness 
 alleged to have resulted from the use of canned 
 articles^ have been shown, on investigation, to 
 have been due to other causes, and while un- 
 wholesome meats may sometimes be packed, or 
 small quantities of tin or lead may occasionally 
 be discovered in the contents of the cans, we 
 believe that the danger has been greatly over- 
 rated, and that when the best brands are em- 
 ployed there is practically as little risk in the 
 use of tinned as of fresh fish, meats and vege- 
 tables. Let it be remembered, however, that 
 when a can is opened its contents should all be 
 turned out, and that if part only is used the 
 remainder should not be allowed to stand in the 
 can, for in the presence of air metallic impreg- 
 nation is doubtless likely to occur, especially 
 in the case of easily fermentable and acidulous 
 substances. 
 
 Milk is a most valuable food, and largely 
 consumed by the young. If pure, it contains 
 all the substances essential to the support 
 of life, but when robbed of its fat by the 
 
78 Cholera. 
 
 removal of its cream or diluted by the addition 
 of water, as too frequently is the case, it 
 is not only much less nutritious, but it may 
 also serve to propagate disease if an impure 
 water has been added. Numerous cases of 
 typhoid fever have been traced to the use 
 of polluted water in adulterating milk, and 
 it would be well if a much closer inspection of 
 the milk sold in our cities could be made. 
 Fortunately skimming and watering are the 
 only adulterations usually practiced, and the 
 common notion that calves' brains, chalk 
 and such like substances are frequently 
 added to milk is a vulgar error. Borax and 
 carbonate of soda are sometimes employed as 
 preservatives, but in the quantities used do no 
 great harm. No easy tests exist by which we 
 can with certainty detect the partial removal 
 of cream from milk or the addition of water in 
 moderate quantity, for the indications of the 
 lactometer are not absolutely to be relied upon, 
 and the amount of cream measured by volume 
 will vary considerably, according to circum- 
 
The Hygiene of Food and Deink. 79 
 
 stances, so that, if the milk supplied us seems 
 of poor quality, it may be necessary to have an 
 analysis made and to resort to legal measures 
 for relief, if they be provided. Skimmed milk, 
 however, sold as such, and at a proper price, is 
 a valuable article of food, the sale of which 
 should be regulated, but ought not to be pro- 
 hibited by law. Of course it is entirely unfit 
 for the use of infants. The common notion that 
 milk from one cow is to be preferred for in- 
 fants' use has nothing to recommend it, the 
 mixed milk from a dairy being less likely to 
 be unwholesome. Condensed milk is generally 
 pure and of a good quality. 
 
 The butter with which we are supplied 
 is of varied quality, being sometimes poorly 
 made, though genuine, or containing an un- 
 due quantity of water or salt, or it may be 
 artificial in whole or in part. Oleomargarine 
 properly made is probably not an unwholesome 
 article of food, but it should be sold on its 
 merits and not as butter. It is sometimes quite 
 difficult to detect it, though a bit of lamp wick- 
 
80 Cholera. 
 
 ing dipped in the suspected butter when melted, 
 lit and blown out after burning for a few min- 
 utes will frequently enable us to recognize the 
 sophistication by the unmistakable odor of 
 burnt tallow which may be perceived. Cheese 
 is a valuable food, capable, in part, of taking 
 the place of meat, and is, when well made, 
 wholesome, if not too largely eaten. It should 
 be made from the whole milk, though the 
 much talked of skim- cheeses are not neces- 
 sarily so bad as they are thought to be by some. 
 Occasionally during the process of ripening 
 cheese develops a peculiar poisonous principle 
 which has not been isolated by any chemical 
 tests, but which renders it highly irritating 
 when eaten. There is no way in which this 
 danger can be guarded against, but fortunately 
 instances of this kind are rare. 
 
 We will now consider those foods which 
 are of a vegetable origin. Bread is the staff 
 of life, and flour naturally comes first. It 
 is of many grades, and the highest priced 
 are not always the most economical and nutri- 
 
TheJIygiene of Food and Deink. 81 
 
 tious, since by some processes of milling much 
 of the gluten goes into the middlings and 
 bran. Wheat flour is never intentionally 
 adulterated, and bread not very frequently, 
 though potatoes are sometimes employed 
 in its manufacture to cause it to retain more 
 water, and alum is occasionally employed to 
 whiten that which is made from inferior flour. 
 Baking powders, so generally used in making 
 biscuits and cakes, are mixtures of bi-carbonate 
 of soda, with cream of tartar, acid phosphate 
 of lime, alum, tartaric acid and like substances. 
 While those made from soda and cream of tartar 
 are preferable, little dependence can be placed 
 upon the conflicting claims as to purity or im- 
 purity put forth by the manufacturers. Pow- 
 der sold in bulk is generally of inferior strength 
 and should not be used. Oatmeal is an exceed- 
 ingly valuable food, being much richer in nitro- 
 genous, or tissue-forming matter, than wheat. 
 When of good quality and well cooked it is a 
 most excellent food for both children and 
 adults, especially if eaten with milk or cream. 
 
82 Choleka. 
 
 Rice is a poorer food, being chiefly starch. It 
 should always be steamed and not boiled, for 
 boiling extracts much of the gluten in which 
 it is already deficient. Fresh fruit and vegeta- 
 bles form an essential part of our diet. Only 
 well ripened fruit should be eaten, and vegeta- 
 bles must be fresh and properly cooked to be 
 wholesome. The common notion that the 
 free use of tomatoes gives rise to cancer is 
 not based on any known facts. Sugar is 
 one of the most important food articles. It 
 is chiefly obtained from the sugar cane, but 
 it is also made from the sugar beet, sap of 
 the sugar maple and from sorghum. Granu- 
 lated and loaf sugar are almost perfectly 
 pure, and the notion that sugar is adul- 
 terated with sand, marble dust and the like 
 is an error. Low grade sugars are mixed 
 with grape sugar (starch sugar or glucose), and 
 this is a commercial fraud since the adulterant 
 is less sweet than the cane sugar, but there is 
 no evidence to show that such sugar is un- 
 wholesome. Most syrups consist largely of 
 
The Hygiene of Food and Dkink. 83 
 
 glucose, and the maple syrup commonly sold 
 is not genuine, and, in the manufacture of con- 
 fectionery, large quantities of glucose are used 
 on account of its low price. Terra alba (gyp- 
 sum) is used to a considerable extent in cheap 
 candies, and, while not poisonous, it is an in- 
 soluble earthy substance not desirable as a 
 food. Certain poisonous colors are occasionally 
 used by confectioners, and, as a rule, cheap 
 and highly colored candies are to be viewed 
 with suspicion. Most of the jellies, jams and 
 preserves sold in the shops are sheer imitations, 
 made from the cheapest, though not necessarily 
 unwholesome, materials, and their use is not 
 to be recommended. 
 
 Tea and coffee are articles that are fre- 
 quently adulterated. Tea, so called, is often 
 the merest rubbish, and many teas are 
 M faced" with Prussian blue, indigo and 
 other substances. Black teas are generally 
 purer than green, and in purchasing, if a 
 fair price is paid, a good article may generally 
 be obtained. Unground coffee is seldom adul- 
 
84 Cholera. 
 
 terated, but the coffee sold ground generally 
 contains chicory (not unwholesome), and the 
 cheapest varieties are sometimes made up of 
 rye, beans, wheat, peas and the like, with 
 more or less of chicory. Pure coffee (ground) 
 floats upon water and imparts but little color 
 to it, while chicory sinks and colors it rapidly. 
 Spices are generally adulterated, but seldom 
 with harmful substances. Many of the ground 
 spices, as sold in the shops, are largely 
 composed of peas, beans, ground cocoanut 
 shells, stale ships' bread, etc. Mixtures of 
 such substances are manufactured on a large 
 scale and sold to dealers for use in the adul- 
 teration of spices. Mustard is universally 
 mingled with flour and starch, and colored 
 generally with turmeric, though sometimes 
 with poisonous coloring matters. Vinegar is 
 often of inferior strength from an undue ad- 
 dition of water, but is very rarely adulter- 
 ated with mineral acids, as is commonly sup- 
 posed. Olive oil is very largely adulterated 
 with lard oil, cotton-seed oil, etc., but these 
 
The Hygiene of Food and Dkink. 85 
 
 additions are harmless. Cream of tartar, as 
 sold in the shops, is generally of very inferior 
 quality, consisting in some cases of ninety per 
 cent of gypsum. It ought to be purchased of 
 reliable apothecaries. 
 
 The wines, malt liquors and ardent spirits 
 that we drink are adulterated and falsified 
 to a considerable extent, but not with the 
 rank poisons that are considered by some to 
 be their chief constituents. Many wines, like 
 sherry, are artificial mixtures, though not 
 necessarily made from deleterious substances. 
 Much glucose is used in brewing beers and ales 
 to save malt, and there is no real objection 
 to this substitution, and other bitters than 
 hops are occasionally, though rarely employed. 
 Poisonous substances like cocculus indicus 
 and nux-vomica are practically never used, 
 though we hear much said about them. Dis- 
 tilled liquors are chiefly adulterated by dilu- 
 tion with water and colored with caramel. 
 Much of the brandy, so called, is a mere imita- 
 tion of the real article, but the common idea 
 
86 Cholera. 
 
 that such liquors are manufactured from aqua 
 fortis and oil of vitriol is a vulgar error. In the 
 compounding of liquors, as in the preparation 
 of other food articles, there is dilution, imita- 
 tion and other deception, but positively harm- 
 ful adulterations fortunately are the exception 
 and not the rule. 
 
 We come now, and in conclusion, to speak 
 brieily of water and the impurities which 
 it may contain, and when we remember that 
 many diseases are propagated by the use of de- 
 filed waters, and possibly, as regards a certain 
 class of diseases, more frequently in this than 
 any other way, we have no need to exaggerate 
 the importance of the subject. Surface waters 
 are generally less palatable than those from 
 wells and springs, but unfortunately the color, 
 odor and taste afford little indication of the 
 real quality. Waters which have percolated 
 through the soil are often bright and sparkling, 
 but may, nevertheless, be loaded with impuri- 
 ties, and waters containing the germs of typhoid 
 fever and other filth diseases may be to all ap-

 pearances of very superior quality. As a rule, 
 shallow wells in the vicinity of dwellings and 
 out-houses are to be viewed with suspicion, 
 since they may at any time become specifically 
 contaminated, and capable of spreading infec- 
 tious diseases. Especially is this true in thick- 
 ly populated suburban districts where the wells 
 are always in close proximity to privy-vaults 
 and cesspools. Under such circumstances rain- 
 water collected in clean cisterns, or preferably 
 in tanks lined with slate or tinned and burnished 
 copper, but never with lead, should be preferred. 
 Filtration may improve the appearance of 
 a water, but it by no means renders it safe to 
 drink, and many filters are, in reality, worse 
 than useless. In cases where it is necessary to 
 use water of doubtful purity, it should always 
 be boiled, and after cooling the clear water may 
 be poured off from any sediment which has 
 formed. Boiling probably destroys all disease 
 germs, and if care is taken to employ only pure 
 ice in cooling water which has been boiled, there 
 is little risk in its use.

 The complete analysis of potable waters is a 
 laborious undertaking, and can only be per- 
 formed by a competent chemist. Even then the 
 results obtained are often unsatisfactory, and 
 no analysis will enable us to say with certainty 
 that a given water is absolutely pure on the 
 one hand, or certain to produce disease on the 
 other; but an analysis is capable of showing 
 different degrees of purity, and if a water is 
 certainly defiled wuth animal matter it ought 
 not to be used for drinking, even though it 
 may be used for a time without producing dis- 
 ease. The following superficial tests will aid 
 us in forming an opinion as to the quality of a 
 water : Add to some of the water in a clean glass 
 a few drops of a solution of nitrate of silver 
 (strength about twenty grains to an ounce of 
 water), and a few drops of nitric acid; if a pre- 
 cipitate, or even a decided turbidity is produced, 
 chlorides are present in considerable quantity, 
 and may be due to sewage contamination. To a 
 tablespoonful of the water in a wineglass add 
 a drop or two of a solution made by dissolving 
 
The Hygiene of Food and Dkink. 8^ 
 
 twelve grains of caustic potash and three grains 
 of permanganate of potash in a fluid ounce of 
 pure water; if the pink color speedily disap- 
 pears the water may contain abnormal quanti- 
 ties of organic matter. Other things being 
 equal the purer waters will keep the tint longest. 
 Select a clean glass bottle, holding about a pint, 
 and having filled it about two- thirds fall of the 
 water, add half a teaspoonful of pure granu- 
 lated sugar, cork the bottle and allow it to 
 stand in a warm place, and if, at the end of forty- 
 eight hours, the contents of the bottle have 
 become cloudy, milky or opalescent, the water 
 is probably impure. Water which on standing 
 for a time in a warm place exhales an unpleas- 
 ant odor is likewise to be regarded with sus- 
 picion. Of course these tests are by no means 
 infallible, and too much dependence must not 
 be placed upon them, but they are as reliable 
 as any simple tests can be, and if the results ob- 
 tained by them are unfavorable, it will be best 
 to abandon the supply, if practicable, or have 
 a thorough analysis made. On the other hand,

 should these tests fail to show impurity, while 
 other evidences point to the water as a cause 
 of disease, they should not Jbe allowed to refute 
 such evidence, since waters may be of a high 
 degree of purity in a chemical sense, and yet 
 contain matter which, thougtf the chemist can- 
 not recognize it, is capable of giving rise to 
 disease. There is little doubt that cholera and 
 typhoid fever are propagated "more frequently 
 by the use of drinking water to which the ex- 
 creta of those suffering from these disorders 
 have gained access, than in all other ways com- 
 bined, and it behooves us, 'especially at times 
 when these diseases are prevalent, or may be- 
 come so, to look well to the quality of the 
 water which we drink. 
 
CHAPTER VI. 
 
 DISINFECTION. 
 
 Disinfection is the destroying of those micro- 
 organisms, the development of which produces 
 decomposition, disease or death. The sub- 
 stances by which such destruction is produced 
 are called disinfectants. That the sanitary 
 application of disinfection is not a matter of 
 recent date, is shown by the fact that in 1771, 
 during the pest in Moscow, Russian physicians, 
 in order to determine the disinfecting power of 
 sulphurous acid gas, took the garments in 
 which the bodies of several persons dead of the 
 pest had been wrapped, and, after subjecting 
 them to the fumes of the gas for a definite 
 time, caused a number of men condemned to 
 death to put them on and wear them; it was 
 
92 Cholera. 
 
 found that the peculiar power the garments 
 formerly possessed of reproducing the pest 
 had disappeared. Again in 1785 Berthollet 
 made a bleaching powder called "Eau de 
 Javelles," so named from the bleaching estab- 
 ment where it was first made, and from that 
 time to this the powder has been used as a 
 disinfectant. Since 1809, when chlorine was 
 recognized, this powder has been called by the 
 more scientific, but much less euphonious, 
 name of hypochlorite of potassa. It is within 
 comparatively recent years, however, that dis- 
 infection has occupied the prominent position 
 accorded to it at present. As the various 
 aspects of the "germ theory" are developed, 
 the special powers of various substances to 
 modify the action of these microscopic germs 
 are being investigated very thoroughly. The 
 term disinfectant is very loosely used and very 
 poorly comprehended by very many j)ersons. 
 Anything that will remove a bad odor is by 
 them considered to be a disinfectant. It is 
 important that this wrong impression should 
 
Disinfection. 93 
 
 be corrected, because much evil might ensue if 
 only a deodorizer were used when a true disin- 
 fectant was called for. The market is full of 
 patented compounds said, by their manufac- 
 turers, to be powerful disinfectants, when in 
 truth they are nothing more than preparations 
 that will remove bad smells — deodorizers. One 
 step higher, if we take Dr. George M. Stern- 
 berg's division, we come to a class of sub- 
 stances which have the power to prevent putre- 
 factive decomposition, but do not destroy the 
 vitality of the disease germ; these are called 
 antiseptics. Next we come to the true disin- 
 fectants, substances which kill the disease 
 germs, thus rendering them incapable of prop- 
 agation, no matter how favorable the circum- 
 stances under which the attempt is made. It 
 will be at once perceived that it is upon the 
 members of this latter class we place most 
 reliance in time of epidemics, or during the 
 prevalence of infectious disease, for at such 
 times it is not enough that we arrest the growth 
 of the disease germs ; our object is to destroy 
 
D4 Cholera. 
 
 them. The committee of the American Public 
 Health Association have made such careful in- 
 vestigations and performed such elaborate ex- 
 periments to establish some facts which may 
 be taken for a basis for operation, and the con- 
 clusions reached by them are so very generally 
 considered correct that we quote very freely 
 from them. The agents recommended as true 
 disinfectants are, thus far, only three in num- 
 ber, viz. : corrosive sublimate, chlorinated soda, 
 or its equivolent chloride of lime, and per- 
 manganate of potassa. The reader will at once 
 enquire what is done with carbolic acid, cop- 
 peras and like substances. Our answer is, the 
 fiat has gone forth, they are only antiseptics. 
 It must not be supposed that they are to be 
 cast away and forgotten because they are no 
 longer continued in the list of true disinfectants 
 or germicides, not at all; but, as we have said, 
 it is important to recognize distinctly the differ- 
 ence between the effects produced by members of 
 the two classes. Take for example this illustra- 
 tion : If from time to time a solution of cop- 
 
Disinfection. 95 
 
 peras is thrown into a cesspool, putrefactive 
 decomposition of the material in it is pre- 
 vented, and it does not become offensive; if, 
 however, the excreta from a typhoid fever or 
 cholera patient gets into the cesspool, the germs 
 of either disease will go on developing in spite 
 of the copperas, and it becomes a source of in- 
 fection; but they will in a very short time be 
 killed if a sufficient quantity of any one of the 
 substances named as disinfectants be thrown 
 freely into the cesspool, and in a very short 
 time the infecting material is destroyed. When 
 we appreciate the rapidity with which some of 
 these germs multiply, we see the necessity for 
 their destruction. " It has been calculated by 
 Ferdinand Cohn, that if the bacterium termo 
 were unimpeded in its propagation, and if one 
 were to multiply into two in the first hour, and 
 these into four in the second hour, and these 
 into eight in the third hour, and so on, the re- 
 sult would be 16,000,500 in the first day, and 
 281,000,000,000 on the second day, and that in 
 five days time the progeny of this little micro 
 
96 Cholera. 
 
 sco pic body would fill the oceans of the world, 
 so wonderfully numerous and fertile are they." 
 It will be seen that in such a case partial dis- 
 infection will not suffice, for if a single germ 
 be left alive it will be multiplied indefinitely. 
 Beside the three already mentioned, there are 
 two others which deserve mention, and we may 
 call them natural disinfectants; these are heat 
 and fresh air." The best of all disinfectants is 
 fire. Burn up all dangerous things if you can. 
 All rags and remnants of food that have been 
 in contact with patients afflicted with scarlet 
 fever, cholera or other infectious diseases 
 should be thrown promptly into the fire. A 
 large part of garbage that would soon putrify 
 and become dangerous may be burned when 
 there is no other ready means of its disposal. 
 Every household, however poor, can command 
 boiling water. Don't lay aside towels, sheets, 
 pillow-cases, pocket-handkerchiefs, night- 
 gowns or other articles of the kind that have 
 been in contact with the sick, to be washed at a 
 convenient or leisure time, but boil them for an

 hour or two at once. Articles that cannot be 
 boiled without spoiling, may be safely and 
 effectively baked at a temperature of 240° 
 Fahrenheit."* 
 
 In this connection Dr. Sternberg says of the 
 relative value of dry and moist heat : " In dry 
 air the heat penetrates objects so slowly that 
 small packages, such as a pillow or small bundle 
 of clothing, are not disinfected after an ex- 
 posure of from two to three hours to a temper- 
 ature of 140° C. (284 Q F.) Exposure to a tem- 
 perature of 140° C. (284° F.) in dry air for a 
 period of three hours injures most articles re- 
 quiring disinfection (clothing, bedding, etc.) to 
 a greater or less degree. In steam, however, 
 at a temperature of from 105° to 110° C. (220° 
 to 230° F.), we have an agent which quickly 
 destroys all living organisms, including the 
 most refractory spores. From the experimental 
 evidence presented, it is safe to say that the 
 temperature of boiling water will quickly de- 
 stroy the vitality of all micro-organisms of the 
 
 * Health Maxims— Dr. O. W. Wright. 
 
98 Cholera. 
 
 class to which all known disease germs belong, 
 in the absence of spores. Steam, at the tem- 
 perature of 105° C. (220° F.) maintained for 
 one or two minutes, or of 110° C. (230° F.) 
 maintained for ten minutes, will infallibly de- 
 stroy the spores of bacilli, which constitute the 
 most difficult test of disinfecting power 
 known."* 
 
 Next in general value is fresh air — plenty of 
 it, in constant currents. Sunlight should be 
 abundantly mixed with it as an adjuvant. 
 The oxygen of pure air kindles a slow fire in 
 all filth with which it comes in contact. Ozone, 
 sometimes abounding in the atmosphere, is 
 still more potent. Let it freely into houses, 
 cellars, and especially sick rooms. Chloride 
 of lime is one of the best, and, when mixed 
 with hydrochloric acid, produces a gas fatal to 
 every form of germ life. If to chloride of lime 
 an equal amount of hydrocloric acid be added, 
 there will be produced a gas which, by pene- 
 trating every crevice and corner, will reach

Disinfection. 99 
 
 what nothing else can. It will be necessary to 
 place the dish containing the disinfectant high 
 up in the room, because of the density of the gas. 
 It must be remembered that this gas has the 
 power to destroy metallic surfaces, also to re- 
 move color from textile fabrics, and cannot be 
 inhaled at all. All articles liable to injury 
 should, when possible, be removed from the 
 room. Metallic surfaces may be protected by 
 oil or varnish placed upon them. After the 
 room has been closed for twelve hours, sub- 
 jected to the action of this gas, cloths satu- 
 rated with ammonia may be introduced for the 
 purpose of neutralizing what gas may be 
 present. The windows should be opened and 
 the air allowed to circulate freely through the 
 room for twenty-four hours. The chloride of 
 lime itself may be used either in solution or 
 powder, but should be kept in tightly corked 
 bottles. For privies and cesspools one pound 
 of the powder should be used for every thirty 
 pounds of matter. The clothing of the patient

 room, before its removal from the room, should 
 be saturated with some disinfecting solution; 
 but the solution of chloride of lime is not so 
 well adapted to this purpose as is that of the 
 bichloride of mercury. Of even more impor- 
 tance than the disinfecting of the clothing and 
 linen is the disinfection of the dejecta of the 
 patient. For this purpose the solution of 
 which we are now speaking, on account of the 
 rapidity of its action, is most valuable. The 
 following standard solution is recommended: 
 " Dissolve chloride of lime of the best quality 
 in soft water, in the proportion of four ounces 
 to the gallon. Use one pint of this solution 
 for the disinfection of each discharge in 
 cholera, typhoid fever, etc. Mix well and leave 
 for at least ten minutes before throwing into 
 the privy vault or water closet. The same 
 directions apply for the disinfection of vomited 
 matter. For cesspools and privy vaults use 
 one gallon of solution to every gallon of matter. 
 Infected sputum should be discharged directly 
 into a cup half- full of the solution."* A dis-

Disinfection. 101 
 
 infectant somewhat more expensive, and with 
 perhaps no special advantages, is that called 
 Labarraque's solution, bnt the article sold 
 under that name is oftentimes of very inferior 
 quality. For those who prefer to use this 
 preparation rather than that of chloride of 
 lime, the following formula will furnish a good 
 article: Take of chloride of lime eighty parts 
 and put it into four hundred parts of water, 
 keeping in a tightly covered vessel; take of 
 carbonate of sodium one hundred and twenty 
 parts and mix with four hundred parts of 
 boiling water ; when cool, mix the two solutions 
 and add water sufficient to make a thousand 
 parts ; keep tightly corked. Of this, for 
 use, take one part and to it add five parts of 
 soft, water; it may be used the same as chloride 
 of lime. There is an objection to both of these 
 solutions from the fact that they have an un- 
 pleasant odor, that of chlorine. To offset this 
 they have a value from the fact that they de- 
 compose, in place of coagulating, as does the 
 bichloride of mercury, albuminoid substances, 
 
102 Cholera. 
 
 and when such substances appear in the dis- 
 charges of the patient, or in any other way, for 
 disinfection these disinfectants should be used 
 in preference to the bichloride of mercury 
 (corrosive sublimate). This latter, while a 
 powerful and valuable disinfectant, is very 
 poisonous, and the free use of it in the 
 family should be attended with extreme 
 caution. As a means for disinfecting the 
 clothing and linen of the sick-room, as we have 
 already said, it is of great value. Where, 
 also, for any reason whatever, it is impossible 
 to use chlorine gas for the purpose of disin- 
 fecting the room after the removal of the 
 patient, this will be found a valuable solution 
 with which to wash the wood-work, floors, 
 cornices and furniture. Indeed, it is advis- 
 able to have the rooms thus washed, even 
 after fumigation has been resorted to. The 
 solution of bichloride of mercury may be made 
 by taking equal parts of it and common salt 
 and dissolving them in water, the salt in this 
 case acts as a solvent; an ounce of this powder 
 
Disinfection. 103 
 
 may be used to eight gallons of water. It 
 must be remembered that this solution becomes 
 decomposed and the mercury precipitated by 
 coming in contact with copper, lead or tin. A 
 wooden tub or earthen crock is a suitable 
 receptacle for such a solution. As this sub- 
 stance is poisonous, but at the same time odor- 
 less and perfectly clear, it might possibly be 
 mistaken for clear water. To prevent the pos- 
 sibility of this, Dr. Sternberg has suggested 
 that there be mixed with it a small portion of 
 permanganate of potassa. This imparts to the 
 solution a beautiful and very distinctive color, 
 and no fluid containing it would be mistaken 
 for a potable liquid. His formula is: "Dis- 
 solve corrosive sublimate in water in the pro- 
 portion of four ounces to the gallon, and add 
 one drachm of permanganate of potassa to each 
 gallon to give color to the solution. One fluid 
 ounce of this solution," he says, " to the gallon 
 of water will be a suitable solution for the 
 disinfection of clothing. The articles to be 
 disinfected must be thoroughly soaked with 
 
104 Cholera. 
 
 the disinfecting solution and left in it at least 
 two hours, after which they may be wrung out 
 and sent to the wash." * 
 
 One gallon of this solution, diluted with three 
 gallons of water, may be used in privies and 
 cesspools in the proportion of one gallon to 
 every four gallons of matter, or the powder 
 may be used in the proportion of one pound to 
 every ^.ve hundred pounds of matter. Perman- 
 ganate of potassa has very decided germicidal 
 and antiseptic properties, and as a deodorizer it 
 is rapid and complete in its action, but it is not 
 generally applicable as a disinfectant, because 
 of the rapidity with which it is decomposed by 
 organic matter. Mixed with a solution of 
 bichloride of mercury, it serves the double 
 purpose of increasing the disinfecting power of 
 the solution, while, at the same time, it throws 
 a safeguard around its use. 
 
 We have briefly called attention to the best 
 disinfectants; because mention has not been 
 made of others, nor stress laid upon some 
 
 * Medical News, April 18, 1885. 
 
Disinfection. 105 
 
 substances commonly called disinfectants, but, 
 by the division adopted in this book, properly 
 called antiseptics, it must not be thought their 
 value is ignored. They should be used at all 
 times when necessary to keep the atmosphere 
 sweet and clean, but when infectious diseases 
 are present, it is not safe to use any thing that 
 is not a germicide as well as an antiseptic. 
 
 In conclusion, the proin£>t and faithful dis- 
 charge of sanitary duties by officials and indi- 
 viduals is a most essential factor in the preven- 
 tion of cholera, and the maintenance of such 
 hygienic and sanitary conditions as best pro- 
 mote the public health, will make the dread 
 disease a matter of history only.
