After separating the sulphureted hydrogen and carbonic 
acid gases by agitation with liquid potash, the residue, con- 
sisting of the inflammable gas mixed with the proportion of 
olefiant gas produced along with it, was submitted to com- 
bustion. The following table shews the average results of 
a number of these experiments.
