artery and vein on each side, into larger tubes running along 
the flexor tendons above the fetlock. 
It is sufficiently obvious that the lymphatic network 
around the pastern must be constituted by confluent vessels 
ascending from the highly vascular textures of the foot, in 
the same manner as the venous reticulations that are dis- 
posed in this manner beneath and around the coronet. Ana- 
logy also tends to demonstrate, indirectly, that such a richly 
endowed organ as the foot must be provided with an appa- 
ratus which is found nearly everywhere else, and particularly 
in the skin, and which appears to play an important auxiliary 
part in the growth and renewal of vital textures. 
We might even be led to infer that this lymphatic circula- 
tion is very largely developed in the organ from the fact 
reported of Geiger collecting from three to five pounds of 
lymph every day from a wounded lymphatic vessel in a horse's 
foot. And another proof is furnished in the case of certain 
diseases, such as inflammation, suppuration, and ulceration, 
sometimes affecting the whole of the lymphatics of a horse's 
limb in consequence of an injury to the lower aspect of the 
foot.

POISONING OF A DOG BY STRYCHNIA. 
By Messrs. Gowing & Son, M.R.C.Y.S., Camden Town. 
On the 12th of May we were requested to visit a dog 
belonging to a gentleman in Delancey Street, Camden Town. 
The dog was a large one, between a pointer and mastiff, and 
from his attachment to his master, and his docile temper, he 
was the pet of the family. He had been taken out early in 
the morning for exercise full of health and vigour. Upon his 
return home about twenty-five minutes afterwards he was 
observed to look anxious and dispirited ; after a time he 
showed other signs of indisposition; tremors occurred, and 
great prostration ensued, the dog soon fell upon his side and 
became convulsed. When first seen he was in the following 
position : The back was slightly arched with the fore legs 
straightened and the hind legs extended backwards; the 
muscles were very tense and rigid ; the animal uttered a low 
piteous whine of a long duration terminating in a moan of a 
distressing character. He raised his head and looked 
anxiously as we stood watching him. There was twitching 
of muscles at intervals, and sometimes the paroxysms were
