bodies which do not seem to have been before examined. We have 

 as yet met with no discordance in our own results as far as simple 

 bodies are concerned. 



In giving the following numbers, we have not attempted any cor- 

 rection for the loss of electricity which is caused by the high tempe- 

 rature of the platinum dish. 



Mean Electric Effects given by a few substances during the continuance 

 of the fizzing sound which immediately follows the disappearance of 

 the Spheroidal State, 5*8 representing the Electromotive Force of a 

 single Grove's Element.

Iodide of methyle , . In many experiments strong + , but 



in three cases pretty strong — .

* This sample was in fine crystals. Far higher effects (also positive) 

 were obtained from it in powder. 



t This is a very difficult substance to experiment upon.
