PNEUMONIA IN CATTLE, SWINE, AND DOGS, 
Belonging to Lecture XXVIII in the last Number, 
Mr. Youatt. 
Although bronchitis is the usual chest-disease of cattle, 
many cases of pure pneumonia will occur. Working cattle 
are more particularly subject to it, especially those who after 
a hard day’s labour are abandoned to cold and starvation, or 
who, the moment they are turned loose, are suffered to slake in 
the cold brook that thirst by which they have been tormented 
for many an hour. Cows neglected, or too soon exposed to cold 
and wet after calving, are often attacked by inflammation of the 
lungs. It frequently becomes epidemic among them. It occurs 
oftenest in the spring and autumn, and comparatively rarely in 
the winter. When a warm spring and premature vegetation 
succeed to a cold and rainy winter, and at the time that they 
are first sent to pasture, inflammation of the lungs is very rife 
among cattle, and especially in low and flat and marshy situa¬ 
tions, and where the water long lies stagnant over the flooded 
meadows. The same ground that gives the rot to sheep disposes 
cattle to pneumonia. 
Symptoms .—The symptoms are analogous to those in the 
horse; the same rigor, depression, heaving, oppressed pulse, 
coldness of the ears and legs, and roots oj the horns, and heat 
of breath. To these are added diminution of milk, swelling of 
the teats, loss of appetite, cessation of rumination, and some 
swelling of the abdomen. A slight cutaneous eruption along the 
back and sides is a frequent accompaniment of pneumonia in 
cattle, and which we attentively watch. If the eruption is re¬ 
pelled, the inflammation will become more intense, and pro¬ 
bably fatal; if the pustules take their regular course, and break, 
and desquamate, we augur well. There is rarely any acute in¬ 
flammation in these animals in which the skin or the subcu¬ 
taneous tissue does not participate, and that peculiar tenderness 
about the loins accompanies or succeeds the eruption. There is 
the same protruded head, the same obstinacy of standing, the 
same disinclination to move, and a manner of standing even 
more peculiar than in the horse, the fore-legs being placed as 
far apart as possible from the sides. Sometimes there is little 
cough, at others it is constant and distressing, and the sudden 
cessation of it is one of the most fearful symptoms that can occur. 
Occasionally the tumours about the joints, to which cattle are 
so subject, suddenly appear, and we arc pleased to see them ;
