of the Hindus, too, those struck by Mahomedans almost 
invariably bear a date, and as many such issues are met 
with, regarding which I shall have to speak hereafter, a word 
or two on the subject of their dates may not be unwelcome 
to the uninitiated.

Their years reckon from the Hijrah or exodus of Maho- 
med, which took place on the 16th July 622 A. D., and as the 
reduction of the Hijrah dates to those of our era is often 
necessary for the identification of many coins one meets with, 
especially those in which the year is legible, while the name 
of the ruling sovereign is effaced, I append the Hijrah dates 
corresponding to the commencement of each half century of 
our era.
