ENLARGED SPLEEN OF A HORSE.

lon<r, and three quarters of an inch wide. They were nearly 
white, and the one analysed weighed 210 grains. It was so 
hard as to be capable of receiving a high polish, and could 
only be cut or scraped with a knife with difficulty. 
Analysis 1. Heated on platinum foil, a very slight charring, 
accompanied by a faint odour resembling 
burning feathers, was observed. 
2. Hydrochloric acid dissolved all but a minute frac¬ 
tion of the calculus. The solution of the cal¬ 
culus was attended by effervescence, and the gas 
evolved rendered lime-water milky. 
3. Ammonia added in excess to the solution of the 
calculus in hydrochloric acid produced no pre¬ 
cipitate even after stirring the mixture and al¬ 
lowing it to stand. 
4. Oxalate of ammonia gave with the ammoniacal 
solution (3) a bulky white precipitate. 
5. Phosphate of soda added to the solution filtered 
from the oxalate of lime gave a minute pre¬ 
cipitate. 
6. No alkalies were discovered. 
From the results of the foregoing analysis we arrive at the 
conclusion that the calculus was composed of carbonate of 
lime, mixed, however, with very small quantities of nitro- 
genized organic matter and carbonate of magnesia. The 
joint amount of the two latter substances appeared to be so 
small that it was not thought desirable to make a quantitative 
analysis of the concretion. 
ENORMOUSLY ENLARGED SPLEEN OF A HORSE. 
By H. R. Perrins, M.R.C.V.S., Worcester. 
Dear Sir, —In accordance with your wish, I have obtained 
the history of the horse, the spleen of which I sent you. 
The owner, riding seventeen stone,had hunted him for about 
twelve years, during which period his health continued 
apparently good until last August, when his near fore-leg 
and shoulder became swollen ; a dose of physic, &c., however, 
soon reduced it. In November the near hind-leg was 
similarly affected, but it also soon subsided, and nothing 
more was noticed until the first week in December, when 
general emaciation set in, and the animal soon became very
