EXPERIMENTS ON CAMPHOR. 
She manifested an hour afterwards symptoms similar to those we 
have related; but we observed more convulsive movements in 
the muscles of the neck, with sudden agitation and hasty and 
rapid shakes of the head, like to the motions which follow a 
strong* shock of electricity. The animal seemed to be sadly 
frightened. The eye was convulsively agitated; the pupil di¬ 
lated, and the sight totally suspended. The nostrils were much di¬ 
lated, and all the vessels of the skin turgid and prominent. She 
rested her head against the wall, as in vertigo; the jaws were 
at times firmly clenched, and then they w ere agitated by 
strong convulsive movements : when left to herself, the animal 
turned round in a circle, falling and rising again immediately. 
The least noise, like that which is produced by striking the 
ground, augmented these symptoms; a bleeding of six pounds, 
however, sensibly diminished their intensity. The blood appeared 
very red. Two hours afterwards the animal became much 
calmer; but, after a remission of three quarters of an hour, a 
new exacerbation supervened less violent than the first. A 
second bleeding relieved this. This second remission lasted an 
hour and a half. A third attack succeeded, and the animal ran 
round as she did at first; a little while after was a fourth attack, 
accompanied by clenched teeth. We counted nearly eighty ar¬ 
terial pulsations in a minute, and observed that the general 
convulsive movements were in the flexor muscles, and at the 
moment when the heart struck against the side, as if each con¬ 
traction of that organ produced the effect of an electric shock. 
The animal felt a little calm after this violent agitation ; she re¬ 
turned to the stable, and laid down, but with a great deal of 
pain, and immediately stretched her limbs stiffly out. The pulse 
was small and hard, and had reached one hundred, and the skin 
was covered with perspiration. At the end of twelve hours the 
pulse and the respiration were still more accelerated. The horse 
rolled and struggled with her utmost force; so, that to put an 
end to her sufferings, it was decided to bleed her to death. 
Post-mortem Examination .—The mucous membrane of the 
point of the coeeum was red, livid, infiltrated, soft, without any 
smell but that of camphor. It was the same in the coeco-gastric 
portion of the colon. The food contained in this last intestine 
was very dry. The small intestines presented nothing remark¬ 
able. The stomach contained a quantity of liquid which smelt 
strongly of camphor. The rugae of the left cavity of the 
stomach were red. The tissue of the kidneys was yellow, 
and the mucous membrane and the bladder slightly inflamed. 
The uterus was full of a white matter, which appeared of an al¬ 
buminous nature. Its internal membrane presented a great num-
