We notice that the order of two metals in that table is 

 sometimes reversed. Thus the theory of equal velocities of: 

 agitation of electrons leads to values of p ranging not from 

 1 to 3, but from 2 to nearly 7. They are never less than 2. 



For sodium light the formula (36) becomes 



/0 2=143VV v/e(l+^+ ..:\ . . (41) 



In Table II. the values of p 2 and p calculated from this 

 formula are given. Mercury, antimony, and bismuth are 

 omitted, as they have a value of vk/\Cct too great for the 

 initial convergence of the formula. For mercury this value 

 is '465, for antimony "303, and for bismuth *469. These 

 cases necesitate the use of tables of the exponential integral 

 function.
