This is a small further contribution towards the elucidation of the 

 difficvdt group of Indian muridce ; and little or no progress can be 

 made in the investigation of the series until much better specimens 

 are available for examination.

Mineralogy. 



Syepoorite. In all works on Mineralogy, a simple sulphide of 

 Cobalt, Co. S, is said to occur in Rajpootana and to be used by Indian 

 jewellers for giving a red colour to gold. In a recent paper in the 

 Journal by Col. J. C. Brooke, mention is made of a cobalt ore, a sul- 

 phuret, occurring with Copper ore at Khetree. Is this Syepoorite ? 

 There is not a specimen in any of the principal museums of Europe, 

 or at least there was not a few years since, and should a careful ana- 

 lysis confirm the chemical composition assigned to the mineral, it is 

 very desirable that specimens should be distributed.
