 lungs, and thus interfere with the chemical destruction of sugar

EUPTURE OF THE BLADDER. 



It is well known that rupture of the bladder may arise from 

 overdistension with urine ; yet it may occur from other causes, 

 as the following article, contributed by Dr. C. M. Wood, will 

 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,
