with other contagious diseases; also ichorous pneumoni 
relapsing pleuritis, suppurating pleuritis, pleuritis after pi 
monary gangrene or ulceration, empyemia, specific ophthalm 
and roaring. 
The course of this disease and its duration necessarily d 
pends much upon the varying complication, but it may t 
stated as a rule that the cardinal symptoms of the diseas 
when not prolonged by the occurrence of a grave complicatio 
generally disappear in from six to ten days, the temperatu 
becoming normal, the extreme nervous prostration disappea 
ing, and the icteric hue of the sclerotica vanishes, indicatir 
the resumption of normal hepatic functions. Some cases pu 
sue an apparently abortive course, and convalesence occn 
from the third to the fifth day. 
Extensive pneumonia necessarily prolongs the diseas 
delaying convalesence eight to twenty days after the begi 
ning of the pulmonary complication, or, becoming chronic, nu 
extend the disease over several weeks or months, eventual 
leaving the animal more or less incompletely recovere 
Hydrothorax may run a brief or chronic course. Pyothon 
usually leads to early death, so also empyemia, meningit 
pulmonary gangrene and ichorous pneumonia. Severe m 
ocarditis with intermittent pulse generally terminates fatal 
at the third to sixth day. 
The symptoms, complications and sequelas already en 
merated, indicate to a great extent the character of patholo 
ical lesions as revealed by post-mortem examination. Follow 
ing as closely as practicable their universality and importanc 
we find: first, a well marked enlargement of the liver, increasir 
its size very considerably. Its weight ranges from twenty 
thirty pounds, is usually of a markedly yellow hue, the si 
face smooth and glossy, the capsule tense, apparently to tl 
point of rupture, the parenchyma friable. In conformity wi 
this condition, the entire cadaver is more or less deeply ting< 
with bile. The lungs show in most cases more or less exte 
sive pneumonia, at first lobular in character, in more seve
