opposite that of F 2 , by the connection of the A plates of 

 F! and F 2 , but at distance ^ + ^-, and similarly with 

 F 2 and F 3 , so that the distance between plate B of F! 

 and plate A of F 3 is ^ + ~ -f ^-; and the capacity (F) 

 is therefore

When condensers are connected in series their joint 

 capacity is the reciprocal of the sum of the reciprocals of 

 their respective capacities, while in parallel the joint 

 resistance is equal to the reciprocal of the sum of the 

 reciprocals of their respective resistances. In voluntary 

 muscular fibre the sarcomeres are, in my belief, joined up 

 in groups in series as well as in parallel, and it may serve 



a useful purpose to append a practical illustration or two 

 from Submarine Cable Testing and Working, by my name- 

 sake, G. M. Baines, of the Eastern Telegraph Company.
