normal shape. The capsule often becomes thickened. The cut 
surface is smooth and of grayish or brownish red color. The 
malpigIlian corpuscles are usually enlarged and prominent. 
The trabecular tissue of the spleen is often thickened and can 
be seen marking it as whitish lines. The enlargement of the 
spleen is mainly due to the increase of the splenic pulp. The 
enlarged lymphatic glands are grayish or reddish in color and 
sometimes mottled in appearance on the cut surface. Micro¬ 
scopically the enlarged glands show increase of the pulp and 
blocking of the lymph paths. Steel speaks of this disease oc¬ 
curring most often in female animals. The three cases I have 
had occasion to examine have occurred in cows as follows: 
Case i. August i, 1896. Subject, an aged cow, weighing if 
in good condition probably 1000 pounds. The animal had an 
unthrifty appearance. The whole carcass when dressed pre¬ 
sented somewhat of a jaundice condition. The liver had a light 
brown color and was considerably enlarged. Spleen was about 
five times its normal size, and when cut through the cut surface 
presented a brownish appearance. Malpighian corpuscles were 
enlarged and plainly visible ; they were about the size of millet 
seeds and were lighter in color than the splenic pulp. Some 
of the lymphatic glands were enlarged and when cut through 
presented apparently normal gland tissue. 
Case 2. Jan. 10, 1898. Subject, a seven-year-old native 
cow, weighing 900 pounds ; color, red with white spots and in 
poor condition, with staring coat and unthrifty appearance. 
Upon post-mortem the spleen was found to be enormously en¬ 
larged, three feet long, twelve inches wide and four inches thick 
in the thickest portion. The malpighian corpuscles were 
greatly enlarged and of whitish appearance. Lymphatic glands 
all over the body were greatly enlarged. The bronchial lym¬ 
phatic glands varied in size from a hen egg to a goose egg. 
Some of the glands in the pelvic region as well as the lumbar 
lymphatic glands and others were the size of a hen egg and 
larger. 
Dr. S. Stewart reports a case of leucocythaemia in a cow in 
the January number of the American Veterinary Review, 
in 1897, which case it was also my good fortune to examine. 
u The post-mortem examination revealed general emaciation 
with all of the structures and viscera presenting the usual ap¬ 
pearance of emaciated animals, with the exception of the 
lymphatic glands and the spleen. The lymphatic glands in all 
parts of the body were greatly enlarged, varying in size from a
