1.—The Analysis of Nitrous Oxide and 
Nitrous Gas. 
TT'HE methods of analyzing nitrous oxide 
and nitrous gas, described in the following 
pages, derive any value they may possess, 
from their enabling us to demonstrate the 
composition of those gases, by processes 
which admit of being more quickly executed 
than the methods already in use, and which, 
at the same time, are capable of affording 
results approaching as nearly to perfect ac- 
curacy, as is consistent with the nature of 
such investigations. The decomposition of 
nitrous oxide may, indeed, be readily and 
expeditiously effected, in consequence of its 
forming a combustible mixture with hydrogen
