Let us uow introduce the Ihiiits for h. These are (see the paper 

 of Prof. V. D. Waals) for values of »• lying- between R and R\ Z: 



and ^/7?2_Y^^2 ^ 



whilst for values of r between RyS and 2 72 they are: 



— l//?2— V+ and l/i^s— V^/-^^ 

 So with our notations we get (/; =: R [^x — ?*'-')
