was convulsed ; and in four minutes and a half, 

 from the time of the injection being made, he 

 died. Tremulous contractions of the voluntary 

 muscles continued for some time afterwards. On 

 opening the thorax, the heart was found to have 

 entirely ceased acting, and the blood in the cavi- 

 ties of the left side was of a scarlet colour. The 

 stomach was much distended. The pyloric and 

 cardiac portions were separated from each other 

 by a strong muscular contraction. The contents 

 of the former were firm and solid, and in every 

 respect resembled the usual contents of the 

 stomach ; while those of the cardiac portion con- 

 sisted of the food of the animal much diluted by 

 fluid ; so that the solution, which had been in- 

 jected, appeared to be confined to the cardiac 

 portion of the stomach, and to be prevented 

 entering the pyloric portion by the muscular 

 contraction in the centre. 



In the pyloric portion of the stomach the 

 mucous membrane had its natural appearance ; 

 but in the cardiac portion it was of a dark grey 

 colour, was readily torn, and peeled off; and in 

 some parts its texture was completely destroyed, 

 so that it appeared like a pulp, on removing 

 which the muscular and peritonaeal coats were 

 exposed. 



The repetition of the experiment was attended 

 with similar results. The alteration of the tex- 

 ture of the internal membrane was evidently 

 occasioned by its having been chemically acted 

 on by the corrosive sublimate injected into it.
