Cavallo's experiments on the escape of elec- 

 tricity. Ph. tr. 1788. 1. 



Nicholson found, that a point, projecting more or less from 

 ' a large ball, produces more or less the effect of a smaller 

 ball, or of a point, and that a smaller projeciion has the 

 effect of a small ball when it receives than when it emits 

 electricity. Cuthbertson observes, that when the flame of 

 a can(J[e is placed between two balls, the one positive, the 

 other negative, the negative ball only is heated. It may 

 be questioned whether every spark is not rather to be con- 

 sidered as resembling the breaking of a charged jar than as 

 a simple communication.

On Lulliii's card. Nich. 8. III. 223. 



When the experiment of perforating a card is made in 

 air much rarefied, the perforation is near the negative in- 

 ' stead of the positive point. 



Perhaps these effects are ultimately referable to heat and 

 expansion.
