10. If as in the former paper we neglect that part of the 

 force which varies as a greater inverse power of the distance than 

 the second, it is clear that we do not require to calculate higher 

 terms than A v B t ; and to this degree of approximation it is easily 

 found that, writing now r for the distance of the centres, 



A a * V 72 ( 1 It

Substituting, we easily find 

 (V |; - 2) Cfl t = 2A A t + lOB^ + 4A& - 2A t B 



and it is seen that the parts depending on V 2 have disappeared. 

 In the former paper the forces must be doubled throughout. 

 This arises from an error on p. 280, 1. 10, where 4nr must be read 

 for 2tt. In consequence of this on page 286 read 11J2 for n and 

 I/0OJ2 or "014 for 1/50. When this correction is made the 

 expression for the force agrees with the above.
