The Effect of Pressure on a Cadim'um Cell 



By 11. li. Ramsky. 



This work is an exUMisiini of some work done in 1901 (Phys. Rev., 

 Vol. 13, July, 1901), in which the pressure was raised to 300 atmospheres. 

 In 1909 there appeared the work of Cohen and Swinge (Zeit. Phys. Chem. 

 07, n pp. 513. t^ept.. 1909), in which the cell was i)laced under a pressure 



of 750 atmospheres. Within the past year the Department of Physics has 

 secured a compression inimi) extending to 1,00!) kilograms per square cenfi 

 meter (1 atmosphere^=l,033 kilogram per square centimeter) and inasmuch 

 as Cohen ard Swinge's results were not in exact accord with my former 

 results T thought it well to repeat and extend the work.
