Specimens of coal from the Celtnaveena and the Meena- 

 shama collieries were also examined in this manner, with 

 the following results : 



Celtnaveena Coal. — 14,772 grammes gave by ignition 

 11.960 of coke. 



1.091 gramme gave 0.164 of white ashes. 

 Meenashama Coal. — 6.280 grammes gave 5.095 coke. 

 3.778 gave 0.742 of ashes. 



Hence they consist of —

Each of these vai'ieties of coal was examined as to the 

 quantity of oxygen it absorbed by reducing litharge. 

 1 part of Aughabehy coal produced 26 parts of lead. 

 1 part of Rover coal produced 28§ parts of lead. 

 1 part of Celtnaveena coal gave 26 of lead. 

 1 part Meenashama coal gave 25 of lead. 

 100 parts are therefore equivalent 



Of Aughabehy to . 77 parts of pure carbon.

These coals are similar in appearance to the Aughabehy, 

 but are more slaty. When ignited they give off inflammable 

 gas, but do not froth. Their coke is dense. 



It is thus seen that the Aughabehy is the most bitumi- 

 nous of these coals, whilst the Rover is the least so, and 

 that in fact the latter approaches closely in its composition 

 to the anthracite of the Munster coal field.
