210 VETERINARY SURGICAL THERAPEUTICS. 
ful cases, inoculation and malleinization assure the diagnosis. But an 
accidental cutaneous inoculation is possible, and then the evolution of the 
primitive lesion, or of the farcinous bud, may be observed. 
The treatment of a primitive lesion, to be efficacious, must be applied 
early, before the diffusion of the contagion ; but generally, when the initial 
lesion is discovered, the first bacilli that have penetrated in the lymphatic 
channels are already beyond reach, and sometimes the infection is rapidly 
realized through the blood. 
Free destruction of the farcinous bud or cord with the actual cautery, 
or with deep, close points of firing, subcutaneous injections and local ap- 
plications of energetic bactericide solutions, are the rules for local treat- 
ment. 
The best way to treat pseudo-farcy is by cauterization of the wounds, by 
antiseptic washes, baths, or dressings, avoiding the seat of the lesions; by 
perfect cleanliness of the affected regions, and by the internal use of iodine 
and arsenical preparations. (See Zpizoiwc Lymphangitis.

TUBERCULOSIS. 
Frequent in cattle, quite common in dogs, tuberculosis is rare in 
horses, swine, sheep and goats. Among birds, it is most commonly met 
with in chickens, pheasants and parrots. The question as to whether 
the tuberculosis of animals and birds is the same in both, or different, 
is still discussed. Some bird 
species, the gallinaceous, for 
instance, are almost proof 
against tuberculosis of mam- 
malia, but on others (psittace- 
ous) inoculation succeeds easily. 
The ordinary doors of en- 
trance to the bacillus are the 
respiratory and digestive mu- 
cous membranes; and there 
are cases where it penetrates 
through the skin. In all ani- 
mal and bird species, except in 
psittaci, external or surgical 
localizations .are exceptional. 
Frohner has shown that they are relatively common in the parrot. Out 
of 56 observations made at the Berlin school, Eberlein has found lesions 
of the skin in 29 cases,-of the bones and articulations in 14, of the eye
