110 ON DIGITALIS, WITH SOME OBSERVATIONS ON THE URINE. 



The slow %11 of the mercurial column was at first attributed to clots, but on 

 examination none were found to account for it. 



Post-mortem examination made immediately. 



On opening the thorax, the reins wore found much congested. The vessels 

 were then ligatured, and the thoracic viscera removed. The left ventricle was 

 firmly contracted. Left auricle flaccid. The right auricle and ventricle were 

 both distended with blood. Pulmonary artery was full and turgid ; the pul- 

 monary veins empty, or nearly so. Right ventricle contained no clot, but 

 2^ ozs. of dark fluid blood. Left ventricle contained no clot or blood, but was 

 markedly contracted, without any whiteness, however. Blood returning from 

 lungs was quite fluid, and very dark. Descending aorta contained no clot, so 

 the slow descent of the mercury could not thus be accounted for. Bladder was 

 firmly contracted and empty. 



Exp. Y. — Dec. 20. — A large dog — a kind of bloodhound, or a cross between 

 that and a mastiff, was experimented on. It took about 2 oz. of chloroform, 

 which was applied on a thick towel before it was anaesthetised, though no doubt 

 the greater part of this was lost in the application. The time when it began to 

 get the chloroform wa» not noted. I cut down on and cleaned about 1^ or 2 

 inches of the jugular vein, and tied it. After exposing the carotid, which lay 

 very deep, the dog was seized with convulsive tremors, which lasted a short time. 

 Dr. Gamgee then finished the cleaning of the artery, and inserted the nozzle 

 of the hsemadynamometer. The instrument showing the mean onlywiis used.
