EXTRACTS FROM FOREIGN JOURNALS. 
day was decided upon to confirm the fact. A street dog was 
trephined, and about one-third of a syringe of Pravaz filled with 
a filtered solution of a portion of the rachidian bulb of the sus¬ 
pected animal in some distilled water, was introduced under the 
dura mater. The operation seemed to disturb him but little, and 
the wound healed in a few days. 
Instead of showing any bad symptoms between the twelfth 
and sixteen days, as it is usually the case in this experiment, it 
was not until the twentieth that he appeared to be sick. He 
then refused his food, and for the three following days showed 
all the symptoms of rabies, being in state of continued agitation, 
moving constantly about his kennel, tearing his bedding and bit¬ 
ing the sides of his cage. His looks and his voice were altered, 
and he bit furiously at a piece of stick presented to him; it was, 
in fact, rabies, which it was expected would kill him on or about 
the fifth day, the fatal termination in rabies generally taking 
place between the first day and the eighth from the manifesta¬ 
tion of the first symptom. This dog, on the fifth day was better, 
his symptoms having improved, and his nervous irritation dimin¬ 
ished, and in about five days more he was apparently so com¬ 
pletely recovered that his radical return to health was confidently 
looked for when, to the surprise of all, he was a couple of days 
after found dead. Unfortunately, no post-mortem examination 
was made. If this dog died from rabies, two important points 
are to be observed in connection with the experiment. These are, 
the duration of the incubation of the disease thus inoculated, and 
the other is the length of time that elapsed before death took 
place.— Ibid. 
FATAL PERITONITIS FOLLOWING THE ACCOUPLEMENT IN A COW. 
By M. Duranton. 
The act of copulation in cattle varies in some respects from 
that of other mammalia, because of the possibility of the intro¬ 
duction of the organ of the male directly into the uterus. In this 
case this peculiar accident took place, and the violent action of 
the male caused a laceration of the left horn of the uterus. Sev¬ 
eral days after 6he had been served, this cow became sick, and
