I have been occupied for a considerable time since my last report with 

 analyses of iron ores for Col. Drummond, of which the following are the 

 tabulated results : —

f In No. 3 much specular iron and peroxidation of protoxide. 



J Loss from water of combination with the earthy matters and ore. 



§ Some excess from peroxidation. 



We have received from Mr. Hodgson of Darjiling two bottles of water 

 from the Minchu spring, near that station, and from A. Grote, Esq. C. S. 

 some small bottles of mineral water from Sosoneah, North of Hazaree- 

 bagh, and also a larger quantity of a mineral water from Kudjorah in 

 Jessore. Of these three waters I have completed a preliminary examin- 

 ation which will form a paper for the Journal. 



From Mr. Cowan of the Gas Light works, who called for some informa- 

 tion about a yellow earth, of which a quantity was procured in the bazar, 

 and which they find useful to mix with the English fire-clay for their 

 retort furnaces, I have obtained a specimen of the Boghead Cannel coal 

 of Linlithgowshire, which is a great acquisition to the coal collections. 

 In sending it, that gentleman writes : — 



"I have left you as promised a sample of the Boghead Cannel coal 

 found in Linlithgowshire. I have now had a fair trial of the Bengal coal 

 for gas-making and find it very good indeed." 



I have received from Major Ramsay a specimen of a supposed coal 

 shale from the Nepal Terraie, close to the plains, at a place called Hetoun- 

 da, where the mineral, it is said, abounds. It was discovered by a 

 brother of H. H. Jung Bahadoor, and the minister was desirous of having 

 an opinion upon it.
