220 DISEASES OF THE HEART. 



growths of a similar nature, varying in size from a common 

 large pin^s head to a horse-bean. They were all distinctly 

 fibrous in their nature, and could be torn into shreds the 

 same as a piece of macerated tendon. In the centre of the 

 large growth the process of suppuration had commenced. 

 The other cavities of the heart contained no trace of any 

 abnormal products. — (Veterinarian, vol. xxv, p. 1.) 



In the same volume, Mr. Shenton relates a similar case 

 occurring to a horse. He was sent for to a black filley on 

 account of lameness; a month afterwards, he was recalled 

 to her, and then found her at grass in emaciated condi- 

 tion. He considered (she being still lame) the case to be 

 one of rheumatism. Ten days after he had been called in a 

 second time, being about to leave his patient, '^somewhat 

 puzzled as to her case, when, on observing her walk towards 

 the door, I was struck at seeing the blood at each pulsation 

 regurgitate in the jugular veins, as high as their bifurcations. 

 It directly occurred to me. that there must be some obstruction 

 offered to the free course of venous blood through the right 

 side of the heart ; and the more I thought about this, and 

 examined my patient for it, the more firmly I was convinced 

 that such was the case. I then left her, hopeless.^-' A fort- 

 night afterwards Mr. Shenton was informed that she had been 

 ''foimd dead in her box." "I went the following day and 

 examined her. With the exception of two or three en- 

 larged mesenteric glands, nothing was found until we came 

 to the heart, which presented nearly the same appearance as 

 in the former case, only that the tumour was attached to 

 the yielding, and not to the solid wall of the ventricle." 



ANEURISM OF THE AORTA. 



Although aneurism is by no means an uncommon disease 

 in our own bodies, in horses it is comparatively rare ; so 

 rare, that it scarcely has become an object of veterinary 

 practice. Nevertheless, as extraordinary occurrences, ac- 

 counts of cases must be at all times interesting to the 

 Veterinarian, and as such I give those that have come under
