ANEUKISM. 423 



A remarkable instance is to be found in the Veterinary 

 Record for 1849. Mr Parker, of Montgomery, in describ- 

 ing a case of aneurism of the posterior aorta of a horse, 

 says: 



"The patient from which the morbid specimen was taken was a 

 well-bred bay mare, twelve years old, the property of a Mr Evans, far- 

 mer, near this place. 



" I first saw her on the 26th of last August, the owner informing me 

 at the time that she had aborted in March, 1847, and had never 

 appeared well since; but in July of the same year he thought her 

 better, and rode her to Ruabon and back the same day, distance 72 

 miles. Since then she has been gradually losing flesh. 



" On examination, she appeared to be in foal, was very poor, coat un- 

 healthy, staring, and hidebound; the visible mucous membranes were 

 pale, except that a few of the largest vessels were injected, and of a 

 bright scarlet hue ; extremities cold, appetite good, mouth moist, hair 

 in mane and tail easily withdrawn; no pain evinced, but countenance 

 dull and dejected; respiration rather accelerated, and a slight cough 

 present: the respired air was cold, and on placing my ear to the chest 

 there was an absence of the respiratory murmur: the beats of the heart 

 were loud and strong, but intermittent; and there was a peculiar noise 

 following each beat, similar to the sound of the expired air passing off 

 in hurried respiration. The pulse was 70, full and jerking, and the 

 systole so very marked, as seemingly to double the beats of the heart, 

 while the undulations in the jugulars extended nearly to the head: the 

 alvine evacuations and urine were healthy. 



" My prognosis was unfavourable, as I conceived it to be inflammation 

 of the serous membrane lining the cavities of the heart, with tuberculi- 

 zation of the lungs. I consequently gave the owner no hope whatever 

 of recovery; but, as she was a favourite animal, he did not like to have 

 her destroyed, and wished me to place her under treatment. I admin- 

 istered sedative agents, occasionally interposing an alterative, and saw 

 her about four times afterwards. On September 12th she aborted 

 again. 



"The only alteration perceived from the first was increased debi- 

 lity, amounting almost to marasmus, the animal being little more 

 than a walking skeleton. Towards the last the urine became dis- 

 coloured, and she manifested a frequent inclination to lie down, and on
