Law of partition of charges 259 



530] K + L + M compared with B with electrification of different strengths. 

 Sun. Jan. 31 [1773]. Trial plate F enlarged. 



[14 observations with light and heavy electrometer alternately. Arts. 656, 

 658.] 



531] K + L + M with A, B, and C; also D + E + F with K, L, and M; 

 also small crown with K, L, and M; and D + E + F and large ground crown 

 with A, B and C and K + L + M. 



Mon. Feb. i [1773]. Th. 48. N. 16. 

 [20 observations. Art. 657.] 



532] On light visible round edges of coated plates on charging them*. 



Mon. Feb. i [1773]. Th. 48. N. 16. 



Some coated glass plates were placed on pos. side and electrified in usual 

 manner in dark room in order to see whether any light was visible round their 

 edges. With the plates M and L of Nairne and with the small ground crown 

 glass a light was visible round the edges when the light electrometer was used, 

 and nearly equally so with the large ground crown glass. The light seemed of 

 the 2 rather stronger with the plates F and A of Nairne; no light was visible 

 when light electrometer was used, but it was with the heavy electrometer. 



533] Crown A and C and large ground crown with C; also 3 rd dephlegmated 

 wax, plain wax and sliding plate 3 with E + F; also 2 double plates with E, F, 

 and D. 



Mon. evening. Th. 53. N. 15. [25 observations. Art. 655.] 



534] Charge of the triple plate the three plates A, B and C placed over each 

 other, with bits of lead between coatings]. 



The three plates A, B and C were placed over one another with the coatings 

 nearly perpendicularly over each other, with bits of lead between them, so as 

 to keep them at the distance off inches from each other. This compound 

 plate was tried in the usual manner. 



Tu. Feb. 2 [1773]. Th. 50. N. 17$. [9 observations. Art. 677.] 



535] Whether the charge of plate D bears the same proportion to that of another 

 body whether the charge is strong or weak: tried with machine for Leyden vials. 

 [Art. 664.] 



Th. Feb. 4 [1773]. Th. 48^. N. 13*. 



Tried with smallest cork balls and the light straw balls as electrometers'. 



The plate D placed on the neg. side and the sliding tin plates at 23^ inc. 

 dist. from wire.
