422 ANEURISM. 



tation, and the posterior divisions of the aorta as well, and extended 

 even to the origin of the renal arteries. The membranes of the spinal 

 marrow were also highly inflamed above the lumbar region; and the 

 marrow itself was softer than natural, and covered with bloody spots. 

 "The subjoined case occurred in 1826 at the college at Alfort: 

 " A mare was brought in very lame from a sinus in the foot, perforating 

 the long flexor tendon, which was treated for three weeks; when one 

 day, while the foot was being dressed, the mare suddenly reeled about, 

 threw up her head, and fell down. No sooner was she down than her 

 nostrils and chest, and belly and flanks, were all in convulsive action for 

 breath; her limbs became stretched, and her eyes rolled in their orbits. 

 The jugular was opened instanter; but drops of blood only issued. In 

 this very act, death closed the scene. The pericardium was found pro- 

 digiously distended with coagulated blood, looking at first like hyper- 

 trophy of the heart. This coagulum weighed five pounds. The trunk 

 of the aorta was extensively ruptured at its base, and the lesion was 

 evidently the result of attenuation of its coats. 



" ANEURISM OF THE ILIAC ARTERY. 



' "The late Mr King, V.S., Stanmore, showed me a dried preparation 

 a specimen of an aneurismal tumour, communicating, as it seemed 

 to him (for there was much confusion of parts), with the external 

 iliac artery; if not with that, with the gluteal. The aneurismal sac 

 was composed principally of the parts immediately adjacent. In 

 several places it had become ossific : indeed, so large and evidently 

 spreading were some of the patches of osseous matter, that, had the 

 animal survived any great while longer, there is little doubt, ultimately, 

 the whole sac would have become converted into bone. The history of 

 the case was A horse, not worth much, was casually brought into Mr 

 King's yard, with a tumour equal in volume to a large pumpkin, and 

 of an irregularly ovoid shape, upon the postero-superior part of the 

 quarter. Finding it fluctuated, Mr King, by way of experiment, punc- 

 tured the swelling with a lancet. A gush of blood followed the punc- 

 ture. Compresses of tow, cloths, bandages, &c., were immediately 

 applied. In the end, however, the animal became reduced, and died. 



" ANEURISM OF THE RENAL ARTERY. 



" Aneurism of the left renal artery, as large as the aorta, was found 

 by M. Chouard in a horse, who was destroyed on account of a carcino- 

 matous affection of the left kidney. For an account of the case see
