etre cube per degree Centigrade at the temperature of 25^ C.chosen for the measurements. For the prehminary work weare indebted to Mr. F. C. Tsu and S. L. Yang. The measuredvakies of resistivity at 25 C. were always above 10^^ ohms percentimetre cube, and as temperature was held well within .1… … specimen itself had reached the desired temperature. TheefTectiveness of the guard rings was investigated on typical sam-ples by transferring the galvanometer to the guard ring lead.The greatest current measured in this lead was about 20 per cent,of the current flowing to the outer electrode.…
