EXPERIMENT It 



I took a quantity of the condenfed atmo-

EXPERIMENT IV. 



A piece of paper marked with a folution 

 of lead in diftilled vinegar, was fufpended over 

 a quantity of the condenfed moifture, while in a 

 ftate of evaporation ; but no change taking 

 place in the lines marked on the paper, 1 con- 

 cluded no fulphur or inflammable matter was 

 detached. (See Seel, IV. page 32.)

The condenfed moifture evaporated to dry-
