TWO FATAL CASES OF INTEllNAL ABSCESS. 631 
days. On the evening of the second day I was sent for in great 
haste. The horse had been suddenly attacked with a shivering 
fit, the respiration was increased, and his appetite was totally 
gone. On the administration of spirit, eeth. nit. with other febri¬ 
fuge medicine the shivering ceased, and the breathing became 
more calm. 
On the following morning I plainly perceived that it was all up 
with my patient. There was a peculiar agonized expression of 
the eye, a heaving of the flanks, a succession of shivering fits 
alternating with increased heat of the temperature of the body, 
and all betokening the mischief that had taken place. 
On applying my ear to the chest, I directly perceived that the 
sound was different from what I had heard the day before, and 
different from that which is usually heard in cases of Jiydro- 
thorax. It was a dull heavy sound, something like (if you 
will excuse the simile) that which is heard in the act of churn¬ 
ing when the butter is beginning to form ; and it directly struck 
me, that there was either a considerable quantity of coagulable 
lymph or pus formed here. He died on the following day. The 
result justified my surmises, for, on opening the chest, the lungs 
were seen to be much reduced in size, and adhering to the pleura 
costalis. The space between them, the diaphragm, and the 
walls of the chest, where they were not united by coagulable 
lymph, was made up of sacs which contained a very large quan¬ 
tity of thin purulent fluid. There were likewise several ab¬ 
scesses in the right lung, which was in a state of gangrene. 
The next case was that of a horse that was said to have been 
ill a fortnight of the influenza, but for which he had had no pro¬ 
fessional assistance. When I saw him he exhibited the followinor 
symptoms,—a staggering, reeling gait, and partial blindness; 
when he w'as moved, he fell, and went heels over head ; loss of appe¬ 
tite ; pulse oppressed and slow ; breathing not much affected, and 
bowels constipated. He continued in this state from two to three 
days, notwithstanding that he was largely bled, blisters applied 
to the head, and setons under the jaw. Then delirium came on, 
and he laboured under all the symptoms ascribed to what in 
olden times was called mad staggers. Copious depletion was again 
had recourse to; he dropped, and was unable to rise ; and, as the 
last act of kindness, was destroyed. 
On a post-mortem examination, the lungs were found to be in 
a gangrenous state and tuberculous. On examining the head, 
the right hemisphere of the brain was found to be enlarged, and, 
on cutting into the posterior ])ortion of it, a large collection of 
very thin pus escaped, which accounted for all the peculiar cere¬ 
bral affections.
