647] 1773, p. 92 [Art. 557]. The connecting wire to the two plates of 

 9-3 inches contains 1-4 inc. el. The connecting wire to the rosin plates of p. 86 

 [Art. 554], should contain rather more in proportion to its length than this, 

 id est, rather more than -28. 



By p. 93 [Art. 557], the 4 rosin plates seemed to contain about \ inc. el. 

 less when placed close together than at dist. Let us therefore suppose that the 

 charge of 2 rosin plates placed close together with connecting wire between 

 them exceeds twice the charge of i plate by -28 inc. el., and that the charge 

 of 4 plates exceeds 4 times the charge of i by z\ times that quantity, or -7 inc. 

 el. Let us suppose, too, that the charge of the 2 double plates A & B with 

 connecting wire exceeds twice the charge of I by -28.
