Cambridge, August 31. 1850.
_Coins of Constantius II._--The coins of this prince are, from their
titles being identical with those of his cousin, very difficult to be
distinguished. _My_ only guide is the portrait. Gallus died at
twenty-nine; and we may suppose that his coins would present a more
youthful portrait than Constantius II. The face of Constantius is long
and thin, and is distinguished by the royal diadem. The youthful head
resembling Constantius the Great with the laurel crown, _Rev_. Two
military figures standing, with spears and bucklers, between them two
standards, _Ex._ S M N B., I have arranged in my cabinet, how far
rightly I know not, as that of Gallus.
