Absorption of Hydrogen at Red Heat. 
That the basic material had the power of absorbing hydrogen at red heat was 
proved by transferring the combustion tube containing it to the <( absorption 
apparatus.” The tube was exhausted at red heat until no more gas could be 
withdrawn from it. Pure hydrogen was then admitted up to 763 millims. pressure. 
The gradual absorption of the gas is shown by the following pressure records :—
