FUEL TABLES. 



These tables contain all the available information covering 

 the data required which have been published to date. They 

 contain analyses of the fuels, and the heat units as determined 

 by the authors, whose names are given. In some cases it has 

 been necessary to recalculate the results as published by the 

 experimenters to conform with the standard adopted. This 

 applies especially to the coals and solid fuels, the data for 

 which are given based on pure dry coal, i.e., on the combus- 

 tible present. If the actual test of the sample as given is 

 desired, it will be easy to make the necessary deductions. 

 Some of the cokes and some of the natural gases have been 

 calculated, the calculated results being within the limits of 



experimental error in these cases.
