columns. Thus the value 6*58 should go to the adjacent 

 column or even to the second adjacent one. Similarly the 

 value 7*7 should be moved over two columns, and farther 

 down 7*1 and 7*2 to the adjacent column. Again the value 

 17 at the bottom of the table might well represent oxygen 

 and be moved one column back. The distributed places in 

 the table are indicated by a t-

Thus the photographs taken collectively show the two 

 hydrogen lines, a line of atomic weight 4, the carbon atom 

 with two charges, the carbon atom with one charge, the 

 /»wgen atom with one charge, another line that was visible 

 three different plates of atomic weight 22, and a final 



on 



line corresponding to C0 2 with one charge. 



Summary. 



The present investigation maybe summarized as follows: — 

 1. The velocity of the carriers of positive electricity in 

 the case of the hot lime cathode is not great enough to affect 

 a photographic plate upon which they may strike.
