26 Ancient Indian Weights. [No. 1 
Tughlak, in a.v. 1325,* this integer was revived in the form of silver 
coin, and was further retained as a mint standard by his successors, 
till Shir Sh&h remodelled the currency about the middle of the 
sixteenth century. In the same way I have already demonstrated 
elsewhere,} in illustration of an independent question, that a coin retain- 
ing with singular fidelity the ponderable ratio of the ancient purdna, 
was concurrent with the restored kdrsha under Féroz Shah (a.p. 1351— 
1388) and other kings. And to complete the intermediate link, I 
may cite the fact that when the effects of Greek and Scythian inter- 
ference had passed away, the 32-ratc Purdna reappeared in the Punjab 
and Northern India, as the silver currency of the local dynasty of 
Sya’ta and Samanta Deva,} and furnished in its style and devices the 
prototype of the Dehli Cuoua’n series of ‘‘ Bull and Horseman” coins, 
the Diulliwdlas, which were retained, unaltered in wieght, by the 
Muhammedans, in joint circulation with the silver double Dirhams of 
174 grains, of their own system.§ 
Extant specimens of Sydla’s coins in the British Museum weigh 
544 grains and upwards. 
If this double series of weights, extending over an interval of time 
represented by 24 or 25 centuries, and narrowed to an almost identical 
locality, are found not only to accord with exactitude in themselves, 
but to approach the only rational solution of the given quantities, the 
case may be taken as proved. 
The ancient pwrdna hall-marked silver pieces range as high as 
55 grains; copper coins of Rdmadatal| are extant of 137.5 grains; and 
other early coins of about 70 grains ; while, in parallel exemplification, 
the later standard weights, under the Muhammedans at Dehli, are 
found to be 56 and 140 grains. Hence—_ 
140+80 ratis = 1°75 grains.
