0. W. Hinman—New Apparatus for Gas Analysis. 187 
The following analyses were made with this apparatus. 
They show the observations required and the manner of mak- 
ing the calculations. 
Illuminating gas manufactured by the Boston Gas Light Co., 
and of an illuminating power of about eighteen candles. The 
two analyses here given were made with the same sample.
