Shocks in and out of water 



35 



3A (3) no shock, with B (3-6) a very slight shock when torp. was just wetted, 

 none else. 



With long link, not bright, 3 A, (3), sometimes left it, not always; with 

 2 A never. 



With wire of same size bright without link, seemed not to feel it so well. 



With small link not bright no shock with B + A (4-6), but there was with 

 B + 2 A (5-6); with bright wire without link felt shock with B + A (4-6), but 

 not with B (3-6). 



With dirty link 2B + A (8-1), sometimes a small shock, not always; with 

 28 + 2A (9-1), certain. 



603] Tried with Lane's electrom. ; dirt unaltered. 



Tu. May 30 [1775]. 



604] It was tried whether distance on Lane's electrom. at which jars dis- 

 charged was the same at the same separation of straw & pith ball electrom. 

 whether number of jars was great or small f. 



This was tried first by laying small knob'd Lane on wire while jars were 

 charging, and afterwards by charging jars, without Lane lying on wire, to a 

 little greater and little less degree by electrom. than what it was before found 

 that they discharged at; then touching them with Lane, I could not perceive 

 that the number of jars made any difference. 



It was tried by comparing i & 4 jars with straw el. at 2 and by comparing 

 i and 7 rows of battery with pith balls at i. 



It was also tried whether the number of jars electrified affected the separa- 

 tion of straw el.: by connecting 4 jars to the wire & then withdrawing 2 of 

 them. It was not found to be at all affected.
