Historical Review of Natural Gas Analyses. 
The analysis of gases in Europe was of a fragmentary na- 
ture up to 1850 and the methods used were inexact and ex- 
tremely tedious. 
It was not until Robert Bunsen developed his well-known 
set of methods for volumetric gas analysis that this became a 
reliable and convenient form of chemical investigation, and the 
work of this great chemist from 1836 to 1860 includes many 
such analyses. His researches on the composition of gases 
produced in geysers in Iceland were of great value, as were 
also his work on volcanic gases and on gases contained in 
mineral waters.!!* In 1857 he published the first edition of 
his ““Gasometriche Methoden” the first good manual of gas- 
analysis methods. 
Natural gas analyses published during the period from 1850 
to 1875 were largely along the lines laid out by Bunsen. The 
gaseous products of voleanic action were actively studied, and 
a number of men, including Bunsen, Saint Clair Deville, Le- 
blanc, Fouqué, S. de Luca, Ch. Vélain, Diego Franco, and O. 
Silvestri, made extended researches into gases from Vesuvius, 
Cerboli, and. many other volcanic sources. References to a 
number of such papers are given in a later chapter, together 
with some characteristic analyses.!!8 
Gases given off by mineral springs and in mines were also > 
early subjects of investigation. The study of large supplies of 
natural gas for industrial use was almost unknown before
