[Mr. De Morgan, in his _Arithmetical Books_, says that the
earliest edition he ever possessed is that of 1685: and what
edition was not stated. The fourth edition was of 1682, the
twentieth of 1700. The matters cited by our correspondent, which
we have omitted, are in all, or nearly all, editions. We have
heard of _three_ copies of the _first_ edition: one sold in Mr.
Halliwell's sale, one in the library of the Roman Catholic College
at Oscott, and one sold by Puttick and Simpson, as above, in April
last: but we cannot say that these are three _different_ copies,
though we suspect it. Our correspondent's edition is not mentioned
by any one. The _fifty-second_ edition, by Geo. Fisher, appeared
in 1748, according to the Catalogue of the Philosophical Society
of Newcastle.]
_Sanskrit Elementary Books._--Will some one of your correspondents
kindly inform me what are the elementary works necessary for gaining a
knowledge of Sanskrit?
