India Office, WhiteliaU, S.W. 

 2iid June, 1888. 

 SlE,- - 



I am directed by the Secretary of State for India in Council 

 to present to the Geological Society some specimens of Burmese 

 xubies attached to their matrix, which were procured by Mr. Bar- 

 rington Brown, at present employed by Government in examining 

 the mines which came into their possession on the annexation of 

 Upper Burmah. 



Mr. Barrington Brown writes concerning these specimens thus : — 

 " I send * * six specimens of rubies in granular limestone, where 

 they were formed. They were obtained by blasting, under my 

 dii'ection, in a place formerly mined by natives * * * *. As I 

 believe the fact of the ruby being traced to its matrix is new to 

 science, the specimens may prove of interest to scientific men * * *. 

 I should like Professor Judd, President of the Geological Society, to 

 see the specimens." 



I am. Sir, 



Your obedient Servant, 



(Signed) J. A. Godlet. 

 Professor Judd, 



President, Geological Society.

[Abstract,] 



The small hoUow spheres, with varying forms of peripheral 

 appendages, described by Prof. Williamson as Calcisplioirce, were 

 found in the Carboniferous Limestone of Flintshire, and were 

 suggested by him to be possibly Eoraminifera or the reproductive 

 capsules of some marine form of vegetation, although he admitted 

 that no forms hitherto discovered aiforded any definite support to 

 this hypothesis. Prof. Judd expressed a belief that the objects
