EXPERIMENT 30. 



Into the stomach of another frog, two drops^' 

 sether mixed with ten of water were thrown. 



These experiments furnish no other conclu- 

 sion except that opium, sether and spirits of 

 wine, when thrown into the stomach of frogs, 

 in such quantity as to produce any considerable 

 change in the animal, all of them equally di- 

 minish the velocity of the pulse. The effect 

 appeared to be analagous to the experiments 

 made with the same animal in :jection 1st. 

 and are equally as inconclusive. 



Recourse was then had to other animals.
