162 TEXAS OR SOUTHERN CATTLE FEVER.
Case 4 (steer).-I)r. Curtice's notes are as follows: "This animal died September 2,
;liboutnoon. The examination was undertaken about two hours later. Its temper-
ature about one hour and a half before dying was 1060, taken at two separate trials.
Its eyes were inflamed and whitened; after death their interior appeared opaque
and yellowish. When first seen the animal was standing in the pasture; it had
previously been lying down and had paroxysmal attacks, from one of which it after-
wards died. The animal, though the flanks were tucked up, was moderately fat.
The fat had an orange yellow tinge. The spleen was enlarged and tumid with
blood of black-red color, and of blackberry jam consistency. The liver had a heavy
waxy feel, and a decidedly yellowish color. The gall-bladder was normal in size
and full of bile. The kidneys were overlooked. The urine was very high colored,
but not bloody or wine-colored. The abomasum had some slightly reddened patches
on the mucous coat; no ulcerations were seen. The rumen was impacted. The
small intestine contained occasional (lark spots about as large as the head of a lead
pencil. The prominency of some portions of the villous surface was injected with
blood, so that a reddened appearance was presented. The patches of inflammation
were decidedly more abundant in the ileum than in the jej unum. The duodenum was
blackened on its villous surface, and slight decomposition had set in. The odor
was fetid. The lungs contained some blood spots, which appeared to have been
Iade about the time of death. Some scattered lobules were collapsed. One side
was emphysematous. The thoracic walls near the diaphragm were roughened as if
from inflammation. The heart showed blood-red spots, which followed the direction
of the muscles beneath the pericardium. These were more abundant on the left
side toward the apex. Washed clots stained with yellow were found in each half.
The surface of the lungs was stained yellow. The fauces were dark and inflamed,
but this inflammation did not extend into the trachea."
Case 5 (heifer).-September 4. This animal died during the night. "The examnina-
tion took place about 11 a. m., but the morning had been rainy and cold so that
decomposition had not set in to any great extent. She carried a large number of
ticks.
"The abdominal cavity contained rather more than a normal amount of serous fluid.
This fluid was rather dark. One portion of' the mesentery appeared as though there
were some peritonitis present. The fat was of an orange yellow color. The spleen
was enlarged, but the color was nearly normal. The liver had a yellowish cast; it
was beginning to decompose on its concave surface, and more especially toward
that part which was next the duodenum. The gall bladder was tumid and some-
what larger than normal. The left kidney was very dark colored (from decompo-
sition (f)) on the outside, but apparently sound in the central portion. The bladder
contained about a gallon of claret-colored urine. The omasum or manifolds was im-
pacted. The abomasum or fourth stomach was normal. The left lung was normally
contracted, but the right was full and spongy. It presented a yellowish tinge on
section. The heart presented bright red spots underneath the epicardial serous
membrane. These spots had their longest dimension in the direction of the muscles,
and were more abundant in the left portion near the apex. There were clots in each
side of the heart, and that on the left side was slightly washed. The pericardial sac
contained an excess of reddish tinged fluid. The fauces presented but little inflam-
mllation."
'T'le organs reached the laboratory September 5. The spleen shows the same en-
largement as the former ones. The pulp is so soft that it wells out as a tarry black
mass when the capsule is incised. No i)acteria were detected on cover-glass prepa-
rations and three bouillon peptone tubes inoculated with spleen pulp remained sterile.
The liver was pale, emitting a slightly disagreeable odor. The acini appeared dis-
tinct and there was no injection of the bile canaliculi observable. In portions of
the parenchyma a large bacillus had multiplied. Cultures remained sterile. The
gall-bladder was distended with a very thick viscid bile scarcely flowing from the
opened bladder. It holds in suspension rather coarse granules.
