YELLOW TOURMALINE. 



Among the Ceylon diamonds that are seen lor sale in 

 Maulmain, is a yellow jewel resembling a topaz ; but 

 which I find on examination to be yellow tourmaline. 



WHITE TOURMALINE. 



An occasional crystal of white tourmaline is seen 

 among the crystals of the black variety in specimens from 

 the Shan states ; but I have never met with it in the 

 Provinces. 



Inditolite, white variety. 



RED TOURMALINE, 



Red tourmaline is found in Burmah, though it is not 

 seen here, Jameson says the king of Ava gave a spe- 

 cimen to Symes which was valued at five hundred pounds 

 in England. 



Rubditc. 

 Tourmaline rubelite, 



MACLE. 



In the slate strata near the granite east of Tavoy, are 

 numerous crystals of what Hitchcock calls andalusite 

 made ; because with many other mineralogists he thinks 

 andalusite, and chiastolite or made, one species. The 

 crystals are very small, but exceedingly numerous. Oc- 

 casionally their rectangular ends are marked with the 

 Greek Chi, or English X, from which they are called chias- 

 tolite; but more frequently the X is wanting. It is 

 much softer than either andalusite, or chiostalite, as de- 

 scribed in works on mineralogy, but it is quite as hard ag- 

 ate specimens which I have received from America- 



tt must be a very rare mineral in India ; for the Curator 

 of Mineralogy and Geology, of the Asiatic Society's Mu- 

 seum did not recognize it as any mineral with which he 

 vyas acquainted ; and other Indian geologists 7 and miner-
