130 Lecture on the Geology of [No. 9, new series. 



The localities in which coal has been discovered are the follow- 

 ing : — in the Hohinipanga range, west of Karakariki on the Wai- 

 pa ; near Mohoanui and Waitaiheke, in the Hauturu range on the 

 upper branches of the Waipa ; and again in the Whawharua and 

 Parepare ranges on the Northern side of Rangitoto-mountains. 



THE NEW ZEALAND BROWN COAL. 



(*The following are the results of several analysis of specimens 

 of the Drury Brown Coal, sent to England some months ago by 

 Mr. Turnbull. The analysis have been forwarded to me by Mr. 

 Farmer. 



Laboratory, Museum of Practical Geology, 

 Jermyn-st., London, April 13, 1859. 



Sir, — I have completed the analysis of the coal (lignite) which 

 you left at the Museum, and herewith furnish you with the results 

 of the examination. 



I am, Sir, 



Your's obediently, 



Chas. Tookey. 



Brown, Esq. 



Per centage composition of Lignite, from Auckland. 



Carbon 55-57 



Hydrogen 4*13 



Oxygen 15*67 



Nitrogen 1*15 



Sulphur 0-36 



Ash 9-00 



Water 14-12 



100 00 



Coke 50-78 per cent. 



The amount of sulphur is small, and this will be a point for 

 favourable consideration in the application of the coal for smelting 

 purposes. The whole of the water is expelled at a temperature 

 of 120° centigrade.
