from the stomach) into the jugular veins of dogs and cats. 
In all cases the fluid used was freed from the flocculi and 
other finer particles by repeated filtration under cover ; it was 
generally free from feculent odour, and invariably had an 
alkaline reaction. 
Experiment 1. — Fluid colourless, having a faint smell, 
passed 13 hours after seizure. 5 drachms injected, one hour 
after its passage, into a dog : lassitude, slight purging for 
two days ; feces white, black, and greenish yellow, with slime 
of a leaden hue ; appetite nearly as usual ; recovery. 
Exp. 2. — 3 drachms of same fluid, half an hour later, into 
a cat : animal purged also ; refused food until next day, when 
it seemed well. 
Exp. 3. — 6 drachms of fluid, colourless, smelling faintly, 
passed 10 hours after first attack, and injected into a dog 
three-quarters of an hour after it was passed : symptoms 
same as in experiment 1 ; but the dog was larger. 
Exp. 4. — On a rabbit : fatal from accidental introduction 
of air : animal distressed exceedingly, and dead in 4 minutes. 
Exp. 3. — Fluid colourless, but having a slight feculent 
odour when warm, passed 5 hours after seizure. 5 drachms 
injected 40 minutes after into a dog : animal languid, dis- 
tressed, and moaning, for many hours; feces relaxed for 
two days ; recovery on the third day. 
After voluntarily eating the fluid dejections of cholera- 
patients, both cats and dogs were observed, in several parts 
of Gallicia, during the first epidemic, to die with choleraic 
symptoms.* In some cases, however, no harm resulted 
therefrom ; and Schmidt also observes, that it is common to 
find dogs eating with impunity the vomits of their sick 
masters.-]* Four cases, to w hich we have already had to refer, 
may here be more particularly related. Lieut. K.’s dog, 
after eating a large quantity of the cholera-discharges eva- 
cuated by his master, died with symptoms and post-mortem 
appearances quite resembling those of cholera in man. The 
case recorded by Otto of Breslau, is one in which a dog is 
said to have followed his master into the hospital, ate of the 
vomit, taken cholera, and died. The facts of Dr. Meyer’s 
case are these: about four o’clock in the morning, the master 
discharged, per anum, a fluid resembling chamomile tea, 
of which the dog, previously quite well, soon after partook 
twice ; the dog then lay under the bed until two o’clock p.m., 
* Sup. cit. 
t We do not remember to have heard of dogs eating the evacuations in this 
country. May we assume this to be owing to the better-fed condition of the 
dogs, and to the different habits of the people, as compared with those observed 
on the continent, and in India ?
