THE ELECTRICAL RESISTANCE, ETC. OF ICE. JOtLVSTONE. 127 



Ice was frozen from distilled water in a copper vessel, like 

 that shown in Fig. 1. Connections were then made as shown 

 in Fig. 2, the current passing through the ice being measured 

 by a galvanometer. Knowing the E. !\!". F. of the cells in the
