Professor Gmelin T s Analysis of Diploite. 287 



necessarily resulting from the insecurity of its acquirements 

 and obstruction in the channels of their exchange, and distri- 

 bution ; lastly, the dominion of a dark, gloomy, and debasing 

 superstition, seem to be the sources of most of the evils under 

 which they labour. Under such circumstances, their wars 

 among each other seem to have been merely bloody and fero- 

 cious, displaying but rarely instances of that generous emu- 

 lation in hardy enterprise, by which those of many nations 

 but little advanced in civilization have been occasionally dis- 

 tinguished. 



The character which the British Government shall acquire 

 and maintain by the policy pursued towards these hill states, 

 (many of which hailed its ascendancy as a deliverance,) will 

 be spread far and wide among the extensive, though yet but 

 little known population of Central Asia, and in no situation 

 will the liberal principles of British administration, and that 

 desire of bettering the condition, both civil and moral, of the 

 body of the people, by which our policy is so honourably dis- 

 tinguished, be more apt to be duly appreciated than where our 

 protection has succeeded to the sway of a body of needy and 

 rapacious adventurers. 



Art. XVIII. — Analysis of Diploite, * (Breithaupt.) By 

 C. G. Gmelin, Professor of Chemistry in the University 

 of Tubingen. Communicated by the Author. 



This mineral was given to Mr Breithaupt by Dr Thalackcr 

 in Herrenhut. It occurs upon the island Amitok, near the 

 coast of Labrador, and forms, with carbonate of lime, mica, and 

 feldspar, a heterogeneous mixture, which probably belongs to 

 the primitive rocks. 



• This mineral is undoubtedly the same to which Mr Brooke {Annuls 

 of Philosophy, May 1823, p. 383) has given the name of hutrobite. As 

 the latrubite, according to Mr Brooke, has cleavages in three directions, 

 the name Diploite, which relates to its having two cleavages, is perhaps 

 not quite suitable. This mineral has, according to Mr Brooke, three cleav- 

 ages parallel to the lateral and luminal planes of a doubly oblique prism. 

 The cleavage parallel to the terminal plane is very dull, and the measure- 

 ment obtained from it not to be confidently relied on. It forms angles 

 with the lateral cleavagc3 of about 98° 30' and 91°. The cleavages parallel 

 to the lateral planes form an angle of 93" 30'.
