304 VETERINARY SURGICAL THERAPEUTICS. 
tinuity of the organ. If the tumor envelops the nerve entirely, it is excised 
on one of its faces and each half removed one after the other. At times 
the neryous filaments and the neoplasm are intimately entangled; the 
separation is impossible ; the whole mass must be excised. 
For painful cicatricial parts which succeed neurotomy, excision is the 
most efficacious treatment. The central end of the nerve is isolated, and 
separated ona healthy portion; the neoformed fibrous product is then dis- 
sected. It is ordinarily found intimately adherent to the tissues under- 
neath. Trasbot has thus removed a tumor in a horse, whose size 
was about that of the small finger; its tissue was white, slightly grayish, 
very firm and hard like fibrous tissue; the nervous threads run through it 
separated, leaving between them quite thick layers of that tissue. 
Neuromas of stumps of extremities are also treated by ablation. 
The generalized neuromas, which transform the nerves in true bead- 
roll of tumors, are seen only in cattle (Colin, Morot). The cow of Colin 
had shown no ailment during life ; at the post-mortem, tumors were found 
in the brachial plexus and in all the sympathetic system. At the lumbar 
region, they formed a mass weighing five pounds. The pneumogastrics, 
cervical and subcostal threads of the sympathetic, the inferior cervical 
ganglions and several nerves of the head had isolated tumors of all sizes, 
varying from that of a pin to that ofa goose’s egg. From the observations 
of Morot, it seems certain that these neoplasms, are not rare in bovines. 
During 1885, this author found them in eleven cows; two of them 
had more than 120, one more than roo and two more than 80. The 
nerves of the dorsal, costal and sternal regions, as well as those of the 
legs and of the posterior parts of the neck, were affected. The situation of 
these tumors is most variable: “Some, situated directly. under the neuri- 
lemma, are visible by transparency. The others are difficult to be seen, 
being imbedded among the central nervous threads. By exploration of 
the course of the nerves, they are readily perceived, rolling more or less 
under the fingers.” 
It is surprising that such extensive alterations of the most sensitive tissue 
of the organism‘should remain absolutely silent. As Tiliaux remarks, in man, 
if pain was proportional to the number of the neoplasms, life would be un- 
bearable with such etherism of the nervous system. But as much as 
solitary neuromas are painful, as much those bead-rolls of tumors seem 
compatible with the regular execution of all functions. If lameness or 
manifest pains would occur and that interference would be desirable on 
valuable animals, this would be guided by the results obtained in man. 
Bromide of potassium has proved advantageous (Nicaise) ; aconite, 
antipyrine, salicylate of sod has given good results. Only the large 
neuromas producing pain exceptionally may necessitate extirpation.
