pressed doubts as to the accuracy of these analyses. 
The following four analyses have been gathered from various 
sources, and are given as representing the composition of Mur- 
rysville gas, determined by different analysts at different 
times:

These analyses were made by analysts as follows: 
1. Dr. G. Hay.129 
2. Fuel Gas Company’s well at Murrysville. Analysis by Rodgers 
(no reference given), quoted by Wm. A. Tilden.139 
3. From Lyons Run, Murrysville. Analysis by F. C. Phillips.1%! 
4, F.C. Phillips.182 
The considerable variation in results of these analyses is 
probably due rather to difference in methods than to actual 
change in the composition of the gas. The work of Phillips on 
these and other analyses was done with extreme care and skill. 
It was mostly gravimetric and is worthy of great confidence. 
His conclusion as to hydrogen was checked in several ways by 
delicate methods, and we can have every assurance that hydro- 
gen was absent from the samples which he examined. 
The hydrogen in the other analyses was probably calculated 
from explosion data and consequently is open to doubt. (See 
“General Discussion,” p. 280.) 
A series of analyses was made by Mr. S. A. Ford, chemist of 
the Edgar Thompson Steel Works, in 1884.13
