large this operation often proves of much benefit, by lessening 
the intense pain and irritation of the mechanical pressure of the 
fibres of the metatarsi muscle over the osseous enlargement. 
The operation is quite simple and requires but very little atten¬ 
tion afterwards. 
Tibial Neurectomy .—Resection of the tibial nerve for the 
cure of spavin has been extensively practiced by European vet¬ 
erinarians with somewhat varying success, and at the present 
time the operation is not thought to be of much benefit. Prof. 
Bosi, of the Bologna Veterinary School, has lately recommended 
a double neurectomy at the hock for the cure of spavin, and it 
is claimed that 90 per cent, of the cases so operated on have 
been cured. The operation consists in a resection of the tibial 
nerve and the peroneal nerve.* 
RECENT VETERINARY LITERATURE ON SURGERY.

Presented to the Minnesota State Veterinary Medical Association, July II, 1900. 
The following summary of an article by Huber in the Jour¬ 
nal of Physiology for February, 1900, confirms modern teaching 
on the subject of regeneration of nerve fibres, and is especially 
interesting, perhaps, to those who are doing frequent neurecto¬ 
mies : “ (1) The motor and sensory nerve endings of voluntary 
muscle degenerate after severance of the muscular nerves. The 
motor nerve endings and the extreme distal portion of the mo¬ 
tor nerves degenerate earlier than do the sensory nerve endings. 
(2) The motor and sensory nerve endings in voluntary muscle 
may, under suitable conditions, regenerate completely. The 
motor nerve endings regenerate more quickly than the sensory 
nerve endings. (3) These experiments, it seems to me, show 
clearly that the regeneration of a degenerated portion of a peri¬ 
pheral nerve is brought about by the down growth of the axis
