betwen 16 and 20, the pulse from 48 to 50, and the temperature 
from 39° F. to 38° F. Convalescence was slow, the animal re¬ 
gaining her normal strength only after several weeks. 
2. An eleven-year-old horse, which had pferdestaupe in 1883, 
and brustseuche, under the form of pneumonia of the right lung, 
in the same year, was brought to the clinic on the 22d of June 
for anorexia. The general symptoms were not serious, and the 
exploration of the chest revealed nothing abnormal. The con¬ 
junctiva was pale and anemic; the pituitary membrane moist and 
cool; the cough short and repititious; discharge from the nostrils 
clear and slight; the urine was yellow in character and without 
albumen and rich in chlorides and sulphates. He received choice 
food, and three days after returned to his owner. During this 
period the respiration had varied from 28° down to 14°, the pulse 
from 36 to 48, the temperature from 37.5° to 38.9°. As in the 
first case, there was a slow convalesence. 
It would avail nothing to report other cases of scalma, the 
symptoms in none of them varying materially either in form or 
intensity. 
The acceleration of the respiration and of the circulation, the 
tired condition and the difficulty of locomotion are always noticed, 
as well as the irritation of the anterior portion of the respiratory 
apparatus. The disease is generally mild, and convalesence tedi¬ 
ous. But it is sometimes complicated with pneumonia or pleu¬ 
risy, and in the latter case is very apt to end fatally. 
The progress and mode of eruption of scalma justify us in 
considering it an acute, infectious disease, due to an unknown 
germ or miasma, which originates and operates in stables where 
the conditions necessary to its growth exist. It has often been 
observed that scalma, unlike other contagious diseases, is not com¬ 
municable by simple contact from one animal of an infected to 
another of another stable. The period of incubation varies from 
two to ten days, and like all similar infectious diseases, it acts 
more or less severely, and in a varying length of time, according 
to the temperature, to the receptivity of animals, the degree of 
intensity of the virus, and the hygenic measures employed against 
its extension.
