The additional wire was ran into straw very easily, and was fastened by 

 putting a little wax on the end, which by heat was pressed quite smooth against 

 the end of the straw.

Heavy electrometer blighted 



In the afternoon the blighted straw was by mistake for the other covered 

 for an hour with paper soaked in salt water. After standing about an hour to 

 dry, it was found that when heavy electrometer was made to separate 10 

 divisions, light separated nj. 



The , . straw discharged the electricity as before in * , weight of 



blighted straw 17-8. 



The fair straw was then kept in salted paper in the same manner for about 

 3 hours. 



Tu. morning. Th. 57. N. 23. 



If heavy electrometer separates to 15, 10, 9, 8, light electrometer separates 

 about J less. 



Fair straw discharged the electricity almost immediately, blighted in 

 about 5". 



When fair straw rested on cork ball it was about 30", the. blighted was much 

 longer. 



Weight of fair straw 14-95.
