MINERALOGY. 31 



FLUOR SPAR. 



I have a small specimen of bluish crystals of fluor spar, 

 which the Burman, who brought it, said was found in 

 the northern part of Province Amherst. As the mineral 

 is often found in connection with lead, it is probable they 

 will be found together in these Provinces. 

 Filiate of lime, 



SELENITE. 



A fine transparent crystal of selenite in the shape of 

 a parallelopipid was brought me by a Burman, who said 

 it was found in Amherst Province. 



Crystallized sulphate of lime.

FIBROL'S GYPSUM. 



A fine variety of fibrous gypsum is seen in some of 

 the China shops ; but it is brought, the Chinese say, from 

 China. They use it in medicine, and say " it is very 

 cooling" ! 



Sulphate of lime.

GRANULAR GYPSUM, 



Gypsum is found near the banks of the Tenasserim in 

 about latitude 13° 40' N. It is granular and friable, and 

 does not correspond in appearance to ordinary specimens; 

 but Dr Morton who analyzed it, pronounced it a decider 1 

 sulphate of lime.
