of Edinburgh, Session ' 31 
X. Olefiant Gas . — The absorber was now carefully dried, dry air 
being drawn through it, while steam was driven through both com- 
partments of the jackets. Then the jacket was filled with water, 
and the air in the reservoir displaced by dry olefiant gas, made 
according to the method recommended by Eoscoe and Schorlemmer 
in their Treatise on Chemistry. The ofefiant gas was driven through 
drying apparatus into the absorber, the tube C being open to the 
atmosphere, until the gas issuing from C burned with a white flame.
