sovereign were known. The latter which is also in my cabinet 

 was published in J.R.A.S,, July 1900, p. 484. The former is 

 the coin above described I now find I was mistaken in call- 

 ing them a half rupee and an eighth of a rupee. Their weights 

 are 56 grains and 273 grains respectively. Both coins are well 

 preserved and appear to have lost but little from their original 

 weight. Taking the weight of the full tanka as 175 grains, 

 which is the generally accepted weight though specimens ex- 

 ceeding 170 grains are hardly ever met with and 168 grains is a 

 high weight, there need be no hesitation in holding that a 

 coin of 56 grains in fine condition is not a half but a third of 

 a tanka. Similarly the piece of 273 grains would be a sixth, 

 and the tiny coins of Nasiru-d-dln Mahmud, Ghiasu-d-din 

 Balban and Jalalu-d-dln Firoz which weigh from 13 to 14 grains 

 would be twelfths of a tanka, and not sixteenths or one anna 

 pieces as hitherto they have been called.

This exquisite little coin was till recently in the cabinet of 

 Mr. H. R. Nevill, I.C.S., Collector of Etawah, by whom it was 

 generously given in exchange to me. Thomas mentions a half 

 rupee of Sher Shah of the same date, but records no details or
