ELECTRICAL PROPERTIES OF SILK. l6l 



vhite stockings were held in one hand, they would 

 epel one another with considerable force, making 

 in angle seemingly of thirty or thirty-five degrees. 

 When a white and black stocking were presented 

 ;o each other, they were mutually attracted ; and, 

 f permitted, would rush together with surprising 

 dolence. As they approached, the inflation gra- 

 ually subsided, and their attraction of foreign 

 bjects diminished, but their attraction of one an- 

 ther increased ; when they actually met, they be- 

 anie flat, and joined close together like as many 

 olds of silk. When separated again, their electric 

 irtue did not seem to be in the least impaired for 

 laving once met ; and the same appearances would 

 >e exhibited by them for a considerable time. When 

 he experiment was made with two black stockings 

 n one hand, and two white ones in the other, they 

 vere thrown into a strange agitation, owing to the 

 ttraction between those of different colours, and 

 he repulsion between those of the same colour, 

 'his mixture of attractions and repulsions made 

 he stockings catch at each other at greater distances 

 han otherwise they would have done, and afforded 

 a very curious spectacle. 



When the stockings were suffered to meet, they 

 tuck together with considerable force. At first Mr 

 jymmer found they required from one to twelve 

 >unces to separate them. Another time they raised 

 seventeen ounces, which was twenty times the
