produced by a condeused discharge at about 3 rmii. pres- 

 sure from nitrogen which is ahnost but must not be ob- 

 solutely pure. More recently an ex-student of one of us, 

 Mr. Grubb, now working with Dr. Wendt at Chicago, 

 writes us that he has produced an active modification 

 of nitrogen in the alternating corona. The term pro- 

 posed is ''nizone". They are studying the properties of 

 this new substance. "Whether it is the same as the Lewis- 

 Strutt active nitrogen remains to be seen. 



AVork is being continued on this process but it is too 

 early to prophesy whether it will ever be a commercial 

 success or not. At all events it is hoped to make the 

 absorption of the gases as complete as possible so that 

 what is learned here may be applied to other problems 

 involving the absorption of gases.
