ANEURISM OF THE AORTA, &C. 
lungs; as is the case with the majority of horses similarly affected 
in the respiratory organs. He suspected, therefore, that the 
attack of the previous day was connected with this ; and from the 
bleeding at the nose, the possibility of abscesses being formed, some 
of which might have been ruptured in the act of coughing, and 
from which at first matter, afterwards blood, might have been dis- 
charged. This, however, was only supposition. On a closer exa- 
mination, the mucous coat of the nose was pale but intact; the 
tongue was coated ; the pulse weak, small, and had decreased to 
30 beats per minute; the contraction of the heart strong; respira- 
tion 15 per minute ; the respiratory muscles convulsive, though 
this, in some degree, had always been the case with this horse ; 
cough short and husky ; alvine evacuations small, dry, and coated. 
The following prescription was ordered : — 
R Pulv. aramon. mur Jij 
„ Kali sulphuric Jviij 
„ Semin, phell. aq Jj 
„ Rad. althese $ij 
f. e. aq. Elect. 
Of this a table -snoonful to be given every two hours, with enemata three 
times a day ; the diet to consist of wet bran. 
On the 19th, the information from the coachman was. that dur- 
ing the night the patient had several times pushed with the chest 
against the manger, while he raised his head as high as the reins 
of the headstall would allow; at the same time lowering the poste- 
rior parts almost to the ground, and once actually had fallen over. 
On examination, the pulse was 26; respiration increased to 16 per 
minute, and laborious; cough more frequent; appetite diminished; 
alvine evacuations more frequent, and softer. On exploring the 
back, a pulsation of 10 per minute was observed. This last symp- 
tom convinced Herr Rohling, that, besides the chronic affection of 
the lungs, there was an aneurism of the mesenteric artery. 
On the 20th, the above-mentioned attacks had been more fre- 
quent ; the pulse had decreased to 22 beats per minute ; while the 
pulsation felt at the back was 14, and the respiration 16. The 
contractions of the heart were strong and bounding; the same 
in the afternoon. The animal died in the night. 
The AUTOPSY, which was made on the 21st, gave the follow- 
ing pathological lesions: — 
Abdominal Cavity . — Caecum and colon in their natural position, 
with normal appearance. The small intestines, the mesentery, the 
adipose tissue around the kidneys, with the posterior portion of the 
pancreas, inflamed. The anterior mesenteric artery enlarged to the 
size of a man’s fist, hard, and of a dark colour. It was filled with 
a hard fibrous mass consisting of the coagulable part of the blood,
