In another passage, however, we are told that Dr. Nedsvetzky, 
of Yaroslav, near Moscow, “ has apparently discovered the 
cholera baCterium, which is developed in enormous quantities in 
the discharges. He found that quinine, camphor, carbolic acid, 
tar, calomel, and chloral had no effeCt upon them ; that opium, 
nux vomica, and chloroform killed them slowly; while tannin, 
sulphate of iron, chlorine water, and dilute sulphuric, nitric, and 
muriatic acids killed them rapidly.” He suggests the latter six 
remedies as the most efficient against cholera. 
The author also considers that the cholera-poison may be 
destroyed by acids, and recommends them — especially dilute 
sulphuric acid — as prophylactics. The value of “ sulphuric acid 
lemonade ” is indeed fully shown by the account given by Dr. 
Curtin of his experience at the Philadelphia Hospital in 1866. 
During the time the acid was used only one new case occurred. 
“ This was a poor lunatic, who, upon tasting it, spat it out, and 
surprised me very much by saying with great vehemence — 
‘ Docther, you call this limonade, but ye can’t desave me ; it’s 
nothing but ile of vitriol.’ ” This woman took the disease, and 
died. Districts where the air is saturated with sulphurous fumes 
have been remarkably free from cholera, and persons whose em- 
ployment exposes them to similar vapours have enjoyed a striking 
immunity. We may here remark that not a few independent 
observers have formed a very high opinion of the value of sul- 
phuric lemonade as a beverage in hot and malarious districts, 
and consider it decidedly superior to the vegetable acids. 
Unlike many diseases, cholera shows little marked preference 
for age, sex, race, or condition of life. The negro race seem to 
suffer more than Europeans. “ The disease was most malignant 
among the lower orders of each community, but the better 
classes were by no means exempt.” 
The author’s strictures on the sanitary condition of many 
cities in different parts of the world, though severe, are only too 
well founded. Much as still remains to be done before the sani- 
tary condition of England is satisfactory, it is some consolation 
to know that we are in advance of our Continental neighbours. 
An interesting and valuable feature in this work is the biblio- 
graphy of cholera, extending to over three hundred pages,
