POISONOUS EFFECTS OF TURPENTINE. 
ministered a little wine and water; but during the day lie began 
to droop — the extreme parts of his body became cold — and, not- 
withstanding all that could be done, he died in the evening. 
The examination after death convinced me of the state of the 
parts : in addition to the former calculi, there were several 
others of smaller dimensions. No damage seemed to have 
resulted to the surrounding parts during the operation : the coats 
of the bladder were a little thickened, and the ureters enlarged. 
The calculus was of an oblong flattened shape, very solid, and 
the size of a duck’s egg. Being requested so to do, I sent it to 
the Watt Institution at Dundee, where all interested in the subject 
may have the calculus exhibited to them. 
The cause of death appears to me to have resulted from the 
weakened constitution of the animal before the operation was per- 
formed . 
THE POISONOUS EFFECTS OF TURPENTINE IN 
THE CASE OF A DOG. 
By the same. 
If you think proper, you may insert the subjoined case, as re- 
lated to me by the owner of the dog ; in order to prove to those 
who are in the practice of administering turpentine, that it is a 
medicine not often to be tampered with. He was a valuable 
pointer, three years old, the property of G. Ritchie, Esq., and 
affected with those parasites called the tape-worm. The owner 
thought that, if turpentine was a good remedy for the human sub- 
ject, it could not be bad for the canine species ; and, reasoning 
from analogy, his dog was tried with 3 iij of oleum terebinthin. as 
a vermifuge. In about three or four minutes after it was adminis- 
tered, the dog began to reel about, his eyes rolled in every direc- 
tion, and violent convulsions ensued. Being rather alarmed at 
this, he suspected that he had poisoned his dog ; and, having no 
medicine beside him, he sent his servant for an emetic ; but in 
the mean time, getting hold of a little olive oil, he gave it to the 
poor animal, which evidently relieved him until the emetic was 
obtained. After this, a respectable practitioner was sent for, and 
a little blood abstracted, &c. Ultimately he recovered. 
This case illustrates the fact, that the mechanism of the horse 
and dog is very different from that of man. Even when the 
structure appears similar, the functions are not so : we must, 
therefore, acquire our knowledge of the therapeutical treatment of 
disease from facts, and not from analogy.
