jections : it suffered no detriment, took its food as usual five 
hours after, and was well next day. Meyer made in all seven 
experiments of this kind. The dogs, whose evacuations had 
been watched several days previously, were kept fasting ten 
or twelve hours before the experiments. 
Experiment 1. — Dejections passed at eight in the evening; 
patient died at night. 4 ounces of rice-water fluid, having a 
slight feculent odour, given to a dog, by mouth and anus. 
During the night, animal took no food ; its bed was mois- 
tened either by urine or stools ; next day he ate briskly, but 
died the following morning at six, without any action of 
bowels. On lifting him up, a whitish fluid gushed out of 
mouth ; peritoneal* coat of intestines pale, soft, and slightly 
injected ; contents of stomach and small intestine a grayish- 
white mucus with epithelium ; slight injection of mucous 
coat of duodenum ; Peyer’s patches especially marked, tumid, 
and many gland-capsules burst ; injection and sugillation of 
large intestine, which contained pretty firm faeces. Blood 
brownish and clotted (not treacley, apparently). Kidneys 
congested ; bladder not described. 
Exp. 2. — Dejections of a patient in blue stage ; had taken 
no remedies ; died sixteen hours after. 1 ounce, almost like 
water, free from smell, given to a large dog by mouth. 
Animal ate and seemed well all day; faeces softer than 
before ; in afternoon, passed a thin blackish fluid ; at eleven 
in the evening was lying weak and moaning; died in the 
night, leaving no further signs of vomiting or purging. — Post- 
mortem: Muscles livid, containing black blood; peritoneal 
coat of intestines injected ; in stomach a dirty-gray mucus ; 
in small and part of large intestine, black fluid, consisting 
mostly of altered blood-corpuscles and epithelium ; gastric 
mucous membrane red ; punctiform redness of duodenum; 
Peyer’s patches turgid ; glands surrounded by red villi ; me- 
senteric veins and right side of heart contained black, greasy 
blood; kidneys congested; in the bladder, a small quantity of 
urine, which coagulated with heat. 
Exp. 3 and 4. — Dejections from a case slightly collapsed ; 
offensive; patient died. 2 drachms to a dog one year old, 
and 1 ounce to another of same age. In the first, no effect 
produced. The other ate well, but for five days had repeated 
purgings of a thin, sweetish-smelling, black substance, like 
that in experiment 2. ^ 
Exp. 5. — Dejections passed twelve hours after attack ; 
patient blue, died. 3 ounces, almost odourless, and filtered 
to remove flocculi, were given to the dog last mentioned, 
twenty days after the former experiment, which had caused
