146 Mr. R. H. M. Bosanquet on 



good deal. They were all examined, and an average taken for 

 each type. 



In order to ascertain whether the law as to a finite limiting 

 moment held good for further subdivision, two short bars were 

 constructed of thin disks of sheet steel, hardened, ground, and 

 fitted. Of these B had the same diameter as A, C a diameter 

 about twice as large. As these bars were short, % could not 

 be accurately ascertained for their subdivisions. But as both 

 were well within the linear range, it is assumed that a law 

 holds similar to that in the case of A. The value of 1$ for the 

 whole bar was ascertained by experiment in each case.
