XY. Di-y Air . — The absorber was dried by keeping both compart- 
ments of tbe jacket full of steam, and drawing dry air tbrougb tbe 
absorber until a U-tube of carefully dried calcium chloride placed 
between C and the suction-pump showed no change of weight in 
the course of an hour. Both compartments of the jacket were 
then kept full of running water, of temperature 12° *2 C., until the 
pressure of the air in the absorber had become constant, when as 
usual the radiator was put in communication with the boiler.
