Stuttgart: Disease.—The outstanding features of Stutt- 
gart disease are the ulceration, necrosis, and gangrene of 
the edges and free anterior portion of the tongue, the 
acute gastro-enteritis, and high mortality—6o to 80 per 
cent. It is comparatively rare to find ulcers of the 
tongue in distemper, and still rarer to see necrotic or gan- 
grenous lesions, whilst the enteritis is practically always 
accompanied by pulmonary or some other classical symp- 
toms of distemper. In canine typhus there is always a 
marked and persistent vomiting (which is frequently 
absent in distemper), followed in a day or two by extreme 
lethargy, which in distemper does not usually supervene 
until a very late stage. The temperature in Stuttgart 
disease is practically normal throughout; there is no 
cough and no ocular or nasal discharges ; young animals 
are less susceptible, and when attacked, seem to suffer 
less severely than old ones, and the disease mostly runs 
an acute course, death taking place in four or five 
days. 
Tubereulosis.—Tuberculosis may be mistaken for dis- 
temper on account of the chronic pneumonia or bronchial 
catarrh present, combined with a gradually increasing 
emaciation, and diarrhoea; but tubercle in the dog runs 
a very prolonged chronic course and there is always a 
history of slight cough which has been long in existence 
and is aggravated by exertion. The temperature, too, is 
irregular—at one time raised, and at another normal—or 
it may be increased by one or two degrees at night. 
Sputum is rarely expelled, as the dog usually swallows 
it, but its microscopic examination would probably reveal 
the presence of acid-fast tubercle bacilli.

the’ termination of the disease, by which time emaciation
