On opium. 4cjf 



His death arofe, in all probability from itiflammatiau^ 

 induced in the abdomen, by the incifion made into it for the 

 introdudion of the folution ; at leaft it mull have had fome 

 influence. 



KxPEkiMENT 30. 



Neither the aqueous folution A. (experiment 3.) nor aJ- 

 kohol and water ^ appeared to affed this frog when dropped 

 tipon the naked eye. 



EXPERIME^NT 31. 



Several drops of the aqueous folution A. (experiment 3.) 

 were dropped into my right eye. It gave me fome degree 

 of pain, which was not of long duration. I felt no other 

 inconvenience from it j but a flight inflammation for fome 

 hours was evident in it. 



Experiment 32. 



After feparating by inflation the flcin and mufcles of the 

 'right inferior extremity of a fine active frog; I injed:ed, 

 at 20 minutes before 4, feveral drops of the aqueous folution 

 of opium la&ucis, A. (experiment 3.) In 5 minutes little 

 effedl was induced. In 10 he experienced fome difficulty 

 in moving it, and it was accompanied with a dragging mo- 

 tion. In 1 5 minutes flill greater difficulty. Upon extend- 

 ing the leg it was retained in that pofition ; whilfl the left 

 was quickly draw^n up to the body ; yet when the right leg 

 was irritated, it was exerted with confiderable facility. 



In 20 minutes the fenfe of feeling feemed to be in fome 

 degree impeded ; for it didnotappear to evince by any con- 

 tractions, that it felt pain from a pointed inftrument in this 

 leg, though in the left^ it was very evident.
