DU NOYER — BITUMINOUS COAL OF THE AltlONA DISTRICT. 91 



In the accompanying table certain townlands are given which form 

 only detached portions of the two great coal-fields. 



As it may interest some of our readers, I subjoin the analysis of 

 the Arigna coals, and that of the ironstones, as given in that valuable 

 work on the ' Industrial Resources of Ireland,' by Sir Robert Kane 

 (second edition, p. 23) : — 



" Aghabeliy Coal. — A rich black coal, easily broken. Specific gra- 

 vity, 1-274. "When heated, it gives off a good deal of inflammable 

 gas, and leaves a light, porous, grey, coherent coke. Analysed in this 

 way, it was found to give, from 100 parts : — .. 



Volatile matter 2310 



Pure coke 6615 



Ashes .............. 10-75 



100-00 



" One part of this coal reduced twenty-six parts of lead to the 

 metallic state ; one hundred parts of it, therefore, represented seventy- 

 seven parts of pure carbon. 



" Celtanaveeny and Meenasliama Coal. — Specific gravity, 1*290. 



Seltanaveeny. Meenashama.

"fiover Coal. — Specific gravity, 1*287. 



Volatile matter 17 70 



Pure coke 74"89 



Ashes 7*41

" One part of it gave by ignition with litharge 28*4 parts of lead ; 

 hence one hundred parts of the coal corresponded to eighty-four of 

 pure carbon. 



" The actual elemental composition of Aghabehy and Rover coals 

 was found to be as follows : — 



Aghabchy. Rover. 



Carbon 79*69 81 04 



Hydrogen 6-24 49 1
