128 VETERINARY SURGICAL THERAPEUTICS. 
upon the constitution of the patient, the diathesis or the organic affec- 
‘tions he may have. 
In veterinary medicine but little is known of the modifications made 
upon traumatisms by infectious and general morbid states, or of the 
mutual influence these have upon each other. Numerous facts, how- 
ever, seem to show that it is the same with animals as with man. Max 
Schiller, in experimenting with rabbits, has shown the influence of 
traumatisms upon tuberculous manifestations, thus elucidating the 
pathogeny of bacillar arthritis. In animals which have had disorders 
of a rheumatic nature, traumatism may give rise to new localization 
‘or to an excitement of the diathesis, especially of articular inflamma- 
tions, when it exists close to a joint. Reciprocally, in those animals, 
-one may observe after wounds some unusual phenomena. In certain 
patients, under the influence of a cancerous diathesis, a traumatism 
may develop a cancer in the injured region. In general, the progress 
and the cicatrization of wounds do not seem to be influenced much by 
-carcinosis as soon as the organism is not below par; we see quite 
-often, in dogs, wounds after the removal of cancerous growths, healed 
‘rapidly without relapse Joco vulnerato; but when carcinosis is old, on 
the road to generalization, and has brought on cachexia, traumatic 
lesions are repaired but slowly, and often accelerate the progress of 
‘propathy. It is the same in cases of sarcomatosis. One of us has re-. 
lated the case of a dog having a sarcoma on the head of the femur, in 
which the generalization of neoplasia took place rapidly, after a needle 
cauterization upon the primitive growth, the nature of which had re- 
mained unrecognized. In diabetic patients the tissues are not only 
impregnated with sugar, but they are also altered in their nutrition: 
spontaneous ulcers may develop themselves, as has been seen in dogs. 
These ulcerations and all accidental traumatisms predispose to gan- 
_grenous and septic accidents. On the other hand, it has been known 
for a long while that certain traumatisms give rise to diabetes: such as 
wounds of the heart and of the superior part of the neck, which drive 
back the cephalo-rachidian fluid and secondarily bruise the floor of the 
fourth ventricle (Cl. Bernard) ; serious lesions of the vertebral column, 
-or violent contusions of the thorax and of the abdomen, which bring 
‘with them functional disturbances in the pancreas or the liver. Albu- 
minuric subjects when wounded are predisposed to cedema, phlegmon- 
-ous inflammations and to suppurative lymphangitis and adenitis. With 
them traumatic hemorrhages are ordinarily abundant, and secondary 
hemorrhages frequent ; with these, also, wounds assume frequently an 
ulcerative character or become complicated with diffuse phlegmons or 
with gangrene. It is known that large suppurating wounds, and bony 
lesions in particular, may give rise to renal lesions (infectious ne- 
phritis) followed by albuminuria. In subjects affected with hemophilia
