with food and dried, dead pulp, the walls of these cavities and the 
adjacent enamel and dentine, were in an advanced state of decay, of a 
bluish color, and in marked contrast with the sound parts ; specimens 
of them I gave to Mr. McEachran, of the Montreal Veterinary College. 
The crowns were much darker than usual , and it occurred to me that this 
was caused by the debris from the gradually receding pulp not being car¬ 
ried off by the circulation , but left to mix with and stain the new formation 
of tooth in the subsequent process of —in this case— impaired nutrition. 
I regretted not having an opportunity of examining the rest of the 
body. _ 
PILES. 
By the Same. 
I was called some time ago to attend a dark brown, middle aged, 
driving horse, belonging to a homeopathic physician of this city. On 
backing the animal out, he moved his hind limbs with difficulty; his 
pulse was about 50 ; and the attendant informed me that he was off his 
feed, and had not passed urine for some time ; on examining his blad¬ 
der with my hand, per rectum, I found it full, and evacuated it by pres¬ 
sure ; I then gave an injection of soap and warm water, and applied 
hot cloths to his loins ; fearing that it might possibly be due to some 
injury to his spine or sublumbar muscles, I had him carefully watched. 
Next morning there was no improvement in his condition, and his blad¬ 
der had again to be evacuated as before; my hand was then pressed 
forward, but nothing like what is said to indicate inflammation of the 
kidneys was found, on withdrawing it, however, it was covered with pus 
and blood ; it may be added, that he evinced great tenderness about the 
anus. On again introducing my hand, a cluster of round grape like 
abcesses, as large as marbles, was found on the superior wall of the rec¬ 
tum, about five or six inches from the anus, there was six or eight of 
these in the cluster; they were easily burst by squeezing them between 
my thumb and fingers, and when my hand was again withdrawn it was 
filled with pus and blood. A few injections of linseed oil and carbolic 
acid was all the treatment he received, and being soon turned out to 
pasture I did not see him again, although I was informed that they had 
not troubled him since.
