2927 (a) GAS BURETTE, Morehead's (patented), as used by the Peoples Gas Light 

 and Coke Co. and others. This Burette, while sacrificing none of the 

 accuracy possessed by the Hempel, Orsat or Mclntosh-Elliott very 

 greatly decreases the time necessary for an analysis. A complete analysis 

 of coal, water, natural fuel, producer, acetylene, or gasoline gas, comprising 

 determinations of any or all of the following constituents, carbon dioxide, 

 illuminants, oxygen, carbon-monoxide, methane, hydrogen and nitrogen, 

 can be made in from twenty to twenty-five minutes. The saving in time 

 is effected by the elimination of the necessity of shifting the gas from 

 one portion of the apparatus to another. With each outfit we send a 

 20-page treatise by Mr. Morehead on Industrial Gases, giving full direc- 

 tions for using the apparatus.

2927 (b) GAS APPARATUS, United States Steel Corporation Official Apparatus, 



for the technical analysis of gases. The special features of this appa- 

 ratus are the accessibility of the auxiliary gases and the central loca- 

 tion of the burette, thus decreasing the error due to the capillary 

 space. The apparatus, as illustrated, mounted on stand, complete 

 with metal sampling tube 50.00
