Striking distance between two flat discs. 
Since the publication of Part I. we have laid clown a fresh smooth curve of the 
striking distance between two flat discs, on the scale of 5 centims. to 1000 cells and 
10 centims. for a millimetre, using the following numbers :—

It is not necessary to give a diagram of the curve, which agrees fairly well with 
the observations ; it runs—
