upon. The operation was performed under chloroform anaes¬ 
thesia. The procedure was the same as described in the opera¬ 
tion above, with the exception that the stone could not be 
crushed with the lithotrite ; the calculus being covered with a 
membrane which prevented the fixation of the instrument on 
the stone. After a number of trials, the instrument was laid 
aside, and with the aid of a trocar and hammer the stone was 
split into several pieces and removed successfully in the follow¬ 
ing way : The trocar was inserted through the wound and 
the urethra into the bladder, while the stone was fixed through 
the rectum towards the neck of the bladder by an assistant. 
With a few gentle blows the trocar split the stone into three 
pieces, which were then removed. After treatment consisted 
in irrigation of the bladder with mild antiseptic solution ; com¬ 
plete recovery took place in about six weeks.]— (A. E.)

Intussusception of Small Intestines [Ch. She cither, 
F.R. C. VS .~\.—Should the question put by the author—“Did the 
struggling on being cast cause it ? ”—be answered affirmatively, 
this is then a sequel heretofore unobserved to add to those al¬ 
ready on the list of accidents likely to occur when animals are 
cast. The subject was an aged horse, which, suffering from 
cartilaginous quittor, had to be thrown and chloroformed for 
operation. This was done after a fasting from food and water
