s begin in the hoof, leading later to disturbances higher 
; these might occur in the muscles first, causing the tail to 
carried to one side, or skipping a little when hurried be- 
e going lame. So in navicular disease, the first changes 
e place in the horny box itself, afterward leading to the 
inges in the bone, etc. 
Dr. Bryden believes in “ hoof culture.” Don’t fire and 
’ter a spavin; it is humiliating to the profession, but attend 
die foot. But to return to this case, he thinks the changes 
;he cord were secondary. 
Mr. Bolton does not agree to this, because sensory changes 
fie cord cannot be secondary. The degeneration is front 
center to the periphery. 
Dr. Bryden thinks that solipeds have a class of diseases 
t no other animal is subject to, and that these progress 
n the periphery in, and cannot be a chorea or anything 
5 that. He thinks we have a splendid subject for investi- 
ion, but holds that it is peripheral disturbance. 
Dr. LeBaw thinks the breaking of a small artery anterior 
he lesions found ought not to cause a degeneration of the 
d, as a small artery is given off at every articulation, and 
stamoses are free there. 
But, Mr. Bolton says, if a nerve’s nutritive supply is cut 
that fibre dies to where it comes in contact with the next 
ve cell, the nerve cell is the center of nutrition for that 
e—that is, for a sensory fibre, while a motor fibre degen- 
:es toward the brain. 
Dr. Marshall wants to know if it can be a hereditary dis- 
5 . Can a blood vessel be hereditarily weakened ? All do 
agree that it is hereditary. 
Dr. Parker remembered seeing a tumor in a cord in which 
i degeneration extended both ways. Can this occur from 
rupture of a blood vessel ? 
Mr. Bolton. That depends upon the size of the area sup- 
d by that blood vessel. 
Motion made by Dr. Hitchcock that we extend to Mr. 
ton and the professors at Clark University a vote of thanks 
the trouble they have taken in investigating this case, 
ried enthusiastically.
