424 ANEURISM. 



rising, which was accomplished with difficulty, she always gave a deep 

 hollow groan. 



" I requested, when she died, they would send me word, which they 

 did on Tuesday last; and on Wednesday morning I made a post-mortem 

 examination. 



"Autopsy, Lungs: left lobe of a light pink colour, studded with 

 tubercles, and towards its anterior lobuli were large vesicles of air; the 

 right lobe contained a few tubercles, and was bordering on congestion; 

 the pericardium was thinner than usual, more capacious, and contained 

 about two pints of serum tinged red; the outer portion of the parietes 

 of the heart was much inflamed, especially towards the superior part of 

 the right ventricle, which in places contained portions of pus ; and 

 there was a great quantity of lymph effused into the cellular substance 

 around the base of the heart. On cutting into the left auricle, the 

 cavity was found dilated, and its lining membrane much inflamed; 

 there was hypertrophy of the walls of the left ventricle, with contrac- 

 tion of the cavity, but no traces of inflammation of the lining mem- 

 brane. The serous membrane lining the right auricle and ventricle 

 was highly inflamed, and the parietes of the right ventricle were 

 unusually thin, as were also its valves: both the kidneys and the uterus 

 were diseased. The intestines, especially the colon, exhibited patches 

 of a similar bright scarlet colour assumed by the visible mucous mem- 

 branes prior to death. The liver was tuberculous; and, in fact, all the 

 viscera appeared affected." 



There are records of scattered cases of aneurism in large 

 numbers, but the most interesting memoir bearing on this sub- 

 ject appeared in the Vienna Quarterly of Veterinary Science 

 for 1852, by Dr Bruckmiiller, one of the Demonstrators in the 

 College. It refers to aneurism of the anterior mesenteric 

 artery. Hering was the first to indicate the frequency of this 

 lesion, and Gurlt doubted Bering's observations. Bruckmiiller 

 examined carefully, from the 22nd May to the 30th Septem- 

 ber, 1851, 65 horses, with a view to determine the frequency 

 of this aneurism, and found only 6 animals perfectly free from 

 it; 59, or 91 per cent., had dilatation of the mesenteric artery to 

 a greater or less extent. In 19 cases there was simple thick-
