LIQUID AIR. 



This cut shows some of the marvels of the new dis- 

 covery, LIQUID AIR. tt looks like water, but is as dry as 

 dust. It is so intensely cold that it will cause ice to form 

 in a blazing fire, and yet if a steel pen is held over it, 

 and lighted with a match, the pen will burn like tinder. 

 A tin dipper held in it for a few minutes becomes so 

 brittle that it will break like thin glass. Cancers sprayed 

 with it can be cut out without the least pain. A human 

 body can be cremated with it completely in fifteen min- 

 utes. The following chapter explains how it is made, its 

 various uses, etc.
