Kachh, tends strongly to confirm the supposition that the Rann was 

 an annex of the sea not very long ago, but was given up, and, on being

5. Additional remarks on the Identification of Ancient Diamond Mines in 

 India.— By V. Ball, M. A., F. G. S. 



(Abstract.) 



In this paper the author finally adopts the view that the mine called 

 Raolconda by Tavernier is identical with the modern Eamulkota. In his 

 previous paper he named this as the alternative in the event of Rawdu- 

 conda not being the place. With the aid of Mr. King the localities 

 mentioned by Tavernier as intervening between Golconda and Raolconda 

 have been fully identified with places between Golconda and Ramulkota 

 where there are still traces of former extensive mines. 



One consequence of this is that the measure of distance called 

 the gos by Tavernier must have been 8 miles, and the league of Tavernier 

 was not the French league, but a paraphrase for the elastic coss. 



The present paper confirms the previous identifications as to other 

 mines and includes information illustrative of several points in the original 

 communication. 



This paper will be published in the Journal, Pt. II, No. 3, for 1881.
