 lunffs, 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-<3isteusion with urine ; yet it may occur from other causes, 

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

 show : 



'^ Sejjtember 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 

 was answered that, having fallen into other hands, he had done 

 little more than merely exercise for the past four months. On 

 examination, the following symptoms were observed: The ani-

 stall, wiih the head elevated, and a fixed stare, as if in the act of 

 urinating. He would then perhaps lie down at full length in hia 

 stall, or throw his head back upon his side, and remain in this 

 position a few minutes ; would again rise and commence pawing, 

 as before. Wlien standing, his hind extremities were wide apart. 

 His pulse was forty-two ; mouth, hot, but moist ; the visible mu- 

 cous surfaces slightly injected ; his respiration little disturbed ; in 

 feet, his symptoms were not violent. I gave an antispasmodic 

 drench, and left him. At eight, A. M., again visited my patient. 

 Found him standing, apparen-tly relieved, yet he occasionally man 

 ifc^ted slight symptoms of a kind of dull abdominal pain. His 

 bowels being costive, I gave him one ounce of cathartic mass, ona 

 drachm of calomel, and half a drachm of pulverized opium, in a 

 baU. At noon he was still the same. Ordered him a bran-masL, 

 which he did not eat ; nor did he drink. Gave an enema. stiu>
