NEURITIS. 391 
«defective cicatrization takes place with formation of a large cicatricial 
tissue, painful, producing lameness: it is a plantar neuritis, which always 
remains limited. This neuritis and a pseudo-neuritis may be observed on 
both ends of a neurotomized leg, even on both legs. It seems as if some 
subjects are predisposed to them. As for other tumors of nerves, ablation 
is followed by the removal of the lameness. Neurotomy performed above 
‘the neuritic portion has therefore its indications. 
In bovines, Gellé has described neuritis (?) of the branches which sup- 
“ply the external face of the shoulder. Due to pricks of the pointed instru- 
ment which their driver uses as a whip, the sensibility would remain but 
‘motricity disappear, and back of the acromion, at its lower portion, a sub- 
-cutaneous tumor, as big as a large pea, was observed. At the onset, Cruzel 
recommends long affusions of cold water, soothing unctions of althea oint- 
‘ment, camphorated or opiate populeum ; then, after a few days, frictions 
-of spirit of turpentine. Soon improvement becomes manifest; regular 
exercise completes the recovery. 
Besides traumatic neuritis, toxic or infectious types are met in animals. 
‘In horses, neuritis of the recurrent has been observed during lead in- 
-toxications. In cattle, after endometritis and peritonitis, Hamburger has 
“observed neuritis of the median and of the crural. In the course of 
-some infections, polyneuritis with muscular pains and sometimes subcuta- 
‘neous ademas resembling polymyositis, may occur. Polyneuritis @ /rigore 
seem rarer than polymyositis of the same nature; but in hemoglobinuria, 
it seems that besides polymyositis there are often polyneuritis, as the par- 
alysis, anesthesia and rapid consecutive amyotrophy have a tendency to 
‘prove. The differential diagnosis is specially based upon the normal or 
~painful state of the nervous cords of the affected surface. In polyneuritis, 
«compressions exercised upon the course of nerves give rise to acute pains ; 
the same compressions are but little painful in polymyositis. 
It is to this variety of neuritis that must be added the alterations, so 
-often observed in the femoral nerve, after “paraplegia.” Goubaux has 
-described them wrongly under the name of “neuromas”’ of the femoral. 
In reading the observations related by this author, it is seen that they affect 
-animals suffering first with “ paraplegia” or “‘ hemoglobinuria” and which 
yemain lame on one hind leg. ‘In all, he mentions the atrophy of the 
triceps cruralis. In Observation I, it is said: “The anterior femoral 
‘nerve was of a larger dimension than that of the opposite side; it pre- 
sented in the middle of its extent a swelling, as big as a hazel-nut, grayish 
red in color; in the middle of which the nervous fibres appear larger and 
with the cellular tissue surrounding infiltrated with serosity.” And in Ob- 
servation II: “The anterior femoral nerve, at the place where it comes out 
«of the pelvic cavity to ramify in the muscles, presented an elongated
