cation N°. 119 a formula was deduced for the resistance of solid 
mercury ; this formula was based upon the idea of resistance vibra- 
tors, and a suitable frequency rv was ascribed to the vibrators wich 
makes 8» = a= 30(8 = PrANCK's number 4.864 < 10 *'). From 
this it was concluded :

way a connection is unexpectedly revealed between the change with 
the temperature of the electrical resistance of metals and their long 
wave emission. 
The results just given for the resistance of mercury are, since they 
are founded upon a single experiment, communicated with all reserve. 
1) In connection with its deduction it is to be noted that the gold-silver thermo- 
element behaved in liquid helium quite so as the experiments in liquid hydrogen 
(Kamerrinm Onnes and Cray, Comm. NY, 1075) made expect.
