EMBOLISM OF THE ILIAC ARTERIES. 
409 
ries,” was destroyed on the 24th of April, and a post-mortem 
examination made immediately afterwards ; but, being then 
in Edinburgh, I had no opportunity of witnessing the dissec- 
tion ; my father and brother, however, attended, and to them 
I am indebted for my knowledge of many of the facts em- 
bodied in this report. There were also present the following 
veterinary surgeons : — Mr. Naylor and Mr. Goodhall, both of 
Soughborough ; Mr. W. R. Marriott, of Cotgrave ; and Mr. 
J. Marriott, of Car-Colston. 
Neither my father nor I saw the mare alive after the middle 
of August, 1870, she being, from that time until her death, 
under the care of Mr. W. R. Marriott. As no definite or 
trustworthy account could be obtained of the pathological 
condition of the mare during the last eight months of her life, 
I pass over that hiatus, and proceed at once to a descrip- 
tion of the lesions observed in the dissection of the carcase. 
First, it may be stated that the body was much emaciated, a 
condition, however, quite incompatible with the manner the 
animal had been fed and managed of late. The muscles, 
although attenuated, possessed the normal colour, and even 
those of the hind extremities showed not the least pallor. 
On the removal of the intestines and pelvic viscera an 
abnormal condition of the terminal part of the posterior aorta 
and of the iliac arteries, evidenced by their bold and grotesque 
contour, was at once recognised. The posterior aorta at the 
part named had an aneurismal-like bulge, whilst the internal 
iliac arteries were distended throughout, the right one more 
so than the other. Each of these vessels presented here and 
there a slight protuberance, which had destroyed its cylin- 
drical character, and given to it an indefinite form. Both the 
external iliacs were considerably increased in size, but the 
enlargement was not uniform. In the right artery the en- 
largement terminated about four inches from the origin of 
the vessel in a swelling of an oval form. In the left artery, 
however, it was continued, even as far as the femoral artery. 
Several small circumscribed melanotic tumours — probably 
lymphatic glands enlarged by the deposit of melanotic matter 
— were noticed in various situations. A tumour of this kind, 
somewhat flattened in form, and about an inch and a half in 
diameter, occupied the angular space formed by the divergence 
of the internal iliac arteries. The contiguous areolar tissue, 
as well as that enveloping the iliac arteries, was of a light 
mottled grey colour, due, apparently, to the deposit of a small 
quantity of black pigment, while the distended parts of the 
iliac arteries themselves exhibited a still darker shade, as though 
they contained a larger amount of similar colouring matter.
