DU NOYER — BITUMINOUS COAL OF THE AllIONA 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, 1 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 Eobert Kane 
(second edition, p. 23) : — 
Agliahehy Coal. — A rich black coal, easily broken. Specific gra- 
vity, 1-274. AVhen heated, it gives olT 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 23-10 
Pure coke 66" 15 
Ashes 10-75 
10000 
" 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 Meenashama Coal. — Specific gravity, 1*290. 
Seltanaveeuy. Meenashama. 
Volatile matter 1910 18-90 
Pure coke 65 87 61 46 
Ashes 15-03 1964

''Rover Coal. — Specific gravity, 1*287. 
Volatile matter 17 70 
Pure coke 74 89 
Ashes 7'41 
100-00 
" 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 : — 
Aghabehy. Rover. 
Carbon ........ 79-69 81-04 
Hydrogen 6-24 491 
Oxygen 352 6 64 
Ashes 10-75 7'41
