all he could to obtain local information for me in Hyderabad. Mr. King on 

 reading my paper has seen his way to identifying the stages between Golconda 

 and Raolconda, some of which, as being common to the routes to either 

 Rawduconda or Ramulkota I have already noted. Mr. King's local knowledge 

 is of course invaluable in an enquiry of this kind, and I may say that I agree 

 with his conclusion and adopt the necessary consequence from it that the 

 league of Tavernier was not the equivalent of the modern French league, as 

 it was taken to be m my calculation, but was only about two miles, and 

 therefore the Gos which contained 4 leagues was equal to 8 miles and was 

 of the same value as the Goto of Heyne.* 



The stages on Tavernier' s route and Mr. King's identification of them 

 are as follow : 



Golconda = Golconda. 



to Canapour = Ghunpoora Lat. 16°'34' N. Long. 78°-G'30". 



to Parquel = Boorgul, Lat. 16°'59' N. Long. 78° 17 -30" E. 



to Cakenol = Kakanoor, Lat. 16° 55' N. Long. 78°-23' E. 



to Canal- Candanor = Kundanool, Lat. 16° 29' N. Long. 78° 22W E. 



to Setapour = Satapoor, Lat. 16°-14'15" N. Long. 78 o -24'30" E. 



to The river = Kistna. 



to Alpour = Alumpoor, Lat. 15°53' N. Long. 78° 11'30" E. 



to Canol ~ Karnul. 



to Raolconda = Ramulkota, Lat. 15° 34' Long. 78° 3'- 15". 



The total distance is given by Tavernier as 17 goss which, if the gos 

 equalled 1112 miles would be 189 miles, but by taking the gos at 8 miles, 

 would be only 13G miles and as Mr. King shows that Tavernier's route was 

 not absolutely direct, the 16 miles, i. e., the excess over the direct distance 

 between Golconda and Ramulkota, namely 120 miles, is at once accounted 

 for. Tavernier gives the distance from his Canol to Raolconda as being 

 2 1 gos this at eight miles to the gos= 20 miles or about the distance from 

 Karnul to Ramulkota. There are the remains of extensive mines at 

 Ramulkota and there is now no room for doubt that it was at this spot 

 that Tavernier saw the diamond bearing stratum, which was very thin, 

 being hooked out by means of iron rods. 



Col. Rennells'f remarks on the subject above alluded to w«re 

 as follow : " Raolconda, a famous diamond mine, is placed in Mr. 

 Montresor's map, about 15 G. miles to the west of Ralicotte, and 12 

 from the north bank of the Kistnah ; but I know not on what authority. 

 Tavernier, who visited Raolconda, gives its distance from Golconda at 17 



* It has teen already stated in the previous paper, p. 32, that Heyne spoke of a 

 unit of measure called the Goto as being equal to 8 miles.
