Heatixg Pottee : — lib. of the coal evaporates 12-371bs. of -water at 

 212° F.; and 1 cubic foot of the coal evaporates 1070-64lbs. of water 

 at 212° F. 



This coal is an extremely valuable band, and although thin, has 

 been -worked very profitably, fetching large prices. In quality 

 and yield of gas, it is considered much superior to "Wigan cannel, and 

 equal to the best Lesmahago coal. Appended is part of a report 

 -written for Messrs. Young, formerly owners of the colliery, Castle- 

 stuart, Creenagh, by Dr. '^Yallace, Gas Examiner to the City of 

 Glasgo-w, -whose determination of the proximate analyses closely 

 resembles my o-wn (see note below). "^
