tvl5 cub. in. being now taken out of jar A, and exposed 

 to solution of caustic potash, 4*75 were absorbed ; and of 7 

 cub. in. out of jar B, the same test took up 5*20 cub. in. 



The residue of jar A being submitted to the usual te^t 

 for oxigen gas, 12.04 out of 100 parts were absorbed : and 

 the residue of jar B being also tried, 18*68 per cent disap- 

 peared.
