the mechanical engineer to ha^e results reported on such a liasis, the 

 interpretation from an ordinary proximate analysis and the recalculation 

 of the calorific value of the coal as analyzed are easily made. To the 

 geologist and chemist the present commercial method is more satis- 

 factory than the suggested modifications and it also gives all that is 

 required to determine the value of coal as a commercial commodity.
