lungs, and thus interfere with the chemical destruction of sugar 
in those organs? This last notion might seem to receive support

RUPTURE OF THE BLADDER. 
It is well known that rupture of the bladder may arise from 
over-distensiun with urine; yet it may occur from other causes, 
as the following article, contributed by Dr. C. M. Woon, wil! 
show: 
“ September 1.—My subject was a bay horse, seven years old, in 
high condition ; that is, fat. On inquiry, I was informed, by the 
man who had the care of him, that when he entered the stable, 
at four o’clock, A. M., he found the horse rolling and tumbling, 
and in great pain. I asked, What has the horse been doing? and

which he did not eat; nor did he drink. Gave an enema, stiw
