458 DISEASES OF THE LIVER AND SPLEEN. 



order from his master to have him shot, which was done on 

 the 30th December. In his belly was found an enormous 

 tumour, occupying on the left side all the interspace between 

 the stomach and the pelvis, and appearing to absorb the 

 entire substance of the spleen. It was globular in its gene- 

 ral outline, measured four feet in circumference, and weighed 

 sixty-seven pounds. Being divided with a sharp knife, the 

 surfaces of the sections presented a marbly aspect, arising 

 evidently from the varied composition of the interior. The 

 superficial parts consisted of a soft, morbid sort of fatty 

 substance, which, as we approached the centre, became 

 mingled with fibro-cartilaginous intersections, of which latter 

 substance the more central portions or body of the tumour 

 appeared to be almost entirely composed, the radii which were 

 sent out among the fatty and superficial parts having in the 

 centre become consolidated into a kind of cartilaginous sub- 

 stance hard to be cut through. And yet it was reddish in 

 its aspect, as though it had been vascular, and here and there 

 presented cysts containing a yellow fluid and gelatinous* 

 matter, looking like serum and coagulable lymph, but which 

 Mr. John Field — who was present at the examination — 

 assured me were, according to Mr. Kyan^s notions, specimens 

 of melanosis. Further investigation clearly demonstrated 

 that this immense tumour was to be regarded as deriving its 

 origin from morbid growth and conversion of the spleen ; for 

 within the portion — about half of that viscus — still remain- 

 ing, little globules or formations of fatty matter were to be 

 found exactly similar in their character to the fatty portions 

 of the tumour itself; and as a farther proof of this original 

 structure, the spleen and tumour were so completely one 

 body, that no line of demarcation, either outwardly in form 

 or colour, or inwardly in composition, was to be made out 

 between them. 



On the 18th January, 1834, Mr. Anderson, V.S., Leices- 

 ter, was requested to visit ^ Contraband,^ a dark brown stallion, 

 rising eight years old, at four years old the best racer in the 

 county, and afterwards hunted for two seasons, carrying 

 fourteen stone, and sometimes three days successively. The
