And further, 

















B== 71-42 



, T = 69-00. 





Calculating 



the 



values of B and T for 100 gr., 



by dividing 



the above values by 2, we find, in close approximation with the 

 numbers previously found directly, 



B = 35-71, T = 34-50. 



The bar was then turned 90 degrees about its axis, the cross- 

 rods were again fastened horizontally to it, and then experiments 

 made just in the same manner. There were obtained — 



X 7 =138-2, Y^iOO-2, ^' = 23-7, Y" = 94-0, 

 Z' = 2355-4 millims., Z" = 2355-3 millims.,
