from the fact that he obtained a striking variation in the 
silver contents of different specimens, the amount ranging 
from 12 to 24 grains. As already stated, it is unthinkable 
that there were coins of equal weight and identical appearance 
which were intended to pass current as pieces of six, eight 
“and ten jaitils simultaneously. If it were attempted at all. 
it is certain that the system could not have iong survived, and 
we must be content to assume an average of 43 ratis or 18°4 
grains of silver and in consequence to regard all the coins of 
“this type as hashtganis. As one-eighth of the tanka, such a 
coin would be of the greatest convenience, and the enormous 
quantities issued by Firoz Shah and his predecessor must have 
done much to make this type the standard currency of the 
day. Fir6z struck but little silver, so far as we can tell. 
there is no reason why we should not in due course discover 
tankas corresponding in type to all the gold issues of the 
reign. 
The introduction of the ’adali or silver coin of 80 ratts by 
Muhammad bin Tughlaq tends to confuse the currency greatly. 
The silver ’adali did not last more than a year or two, ut at

and was obviously in common use. If it were a coin of 24 
jaitils, the silver in its composition would amount to Puce 64

of no analvsis of these coins, but I would incline to the theory 
that they are nisfis of 25 jaitils and that their production was 
limited to the reign of Muhammad bin Tughlag. When we 
are told that coins of 24 and 25 jaitils were current in the 
days of Firéz Shah, it does not follow that they were struck 
by that monarch. : : 
Another problem arises in the coin described as of impure 
silver by Thomas (No. 261) struck in the joint names of 
Muhammad and Firoz Shah. This and the coin with wage! 2!

subsequently by Muhammad when sole king, up to the last 
year of his reign. The coin is very silvery. but is obviously
