EXTRACTS FROM FOREIGN JOURNALS. 
animal is seized and bitten with strength. Tiie animal bites his 
paws or the ground upon which he lays. This lasts from fifty 
minutes to an hour, and deatli from asphyxia would have followed 
had the dose been larger. These symptoms were followed by a 
comatose state, which lasted two or three hours, and then the ani¬ 
mal recovered his general health. 
In another experiment, this time upon a bird, which was 
placed under a glass globe where a small piece of cotton wet with 
a few drops of the essence had been placed, the little animal be¬ 
came agitated, vomited, walked on his hocks, stretched his wings, 
had diarrhoeic passages, and convulsions well marked. Chloral 
and carbonic acid are powerful agents to overcome these con¬ 
vulsions. 
A large rabbit received in the pharynx a spray of carbonic 
acid, then five drops of the essence, (a toxic dose) which was fol¬ 
lowed by another spray of carbonic gas. The convulsions were not 
seen. 
Another rabbit received under the skin an injection of 2£ 
grammes of chloral. As soon as asleep, three drops of the essence 
were injected into the veins of one ear. Nothing is observed. Six 
minutes afterwards he is killed, without convulsions, by an injec¬ 
tion of four drops more of the essence. 
Taking the bird which had been thrown into convulsions by 
the other experiment, lie was placed under a globe containing 
vapors of chloral. The animal sleeps there for a few minutes, 
wakes up, and falls asleep again. 
Again, another bird is placed under a globe filled with vapors 
of chloral. When asleep, he is placed under another containing 
vapors of the essence. He dies without convulsions after remain¬ 
ing there for an hour. 
Death, says Dr. Peyraud, takes place during the convulsions 
by the suffocating spasms it produces, a fact which seems to be 
demonstrated in human rabies. 
From these results Dr. Peyraud hopes to have found an anti¬ 
dote for the development of rabies. 
The remarks of the Doctor conclude with the relation of a case 
of a young man who had been bitten by a mad dog, as proved by
