_Rollin's Ancient History and History of the Arts and Sciences._--It may be
useful to note, for the benefit of some of your student readers, that the
most procurable editions of Rollin's _Ancient History_ are deficient,
inasmuch as they do not contain his History of the Arts and Sciences, which
is an integral part of the work. After having possessed several editions of
the work of Rollin, I now have got Blackie's edition of 1837, in 3 vols.
8vo., edited by Bell; and I learn from its preface that this is the only
edition published since 1740 containing the History of the Arts and
Sciences.
How comes it that the editions since 1740 have been so castrated?
