from the pubes to the sternum, the bladder protruded, distended 
to its fullest capacity, the size of a man’s head. The bladder and 
the urethra were then removed entire, and six pints of urine 
slightly decomposed and dark colored were evacuated by a canula. 
Opening the bladder, a large number of calculi were found, vary¬ 
ing in size from a large pea to minute particles. The canal of 
the urethra was literally packed with calculi, especially in its 
bony portion; the walls of the bladder were hypertrophied, and 
the mucous membrane was slightly congested; the kidneys were 
enlarged and softened, a small quantity of urine was present in 
the hilus of each; one calculus, the size of a pin’s head, was found 
in the pelvis of the right kidney, and two, not quite so large, were 
in the left. The urethral tract was highly inflamed throughout; 
the prostrate gland was enlarged and diseased, also the spleen 
showed deposits ; the calculi, which numbered over four hundred, 
were composed principally of the triple-phosphates. The other 
organs were healthy. A report of the microscopic examination 
of the diseased structures will be given in another article.

uncommon one nor was the treatment especially new, yet the re¬ 
sults were so satisfactory that I think it worthy of a place in the 
Review. 
November 29, 1881, I was called to see a chestnut gelding 
which had been suddenly taken ill, and was apparently suffering 
very much, having some epistoxis. Pulse, 60 ; temperature, 105. 
The following history was obtained : 
The horse some two or three weeks previous had had a slight 
attack of pulmonary congestion, from which lie speedily recov¬ 
ered and resumed his work in about a week, eating well 
and apparently in good condition. 
About eleven o’clock in the forenoon of the day I saw him he
