, and so happy a memory, that
he could not only translate them, without a moment's hesitation, into
Latin or French, but turn, with the same facility, the translations
into the original language in his tenth year.

Growing, at length, weary of being confined to a book which he could
almost entirely repeat, he deviated, by stealth, into other studies,
and, as his translation of Benjamin is a sufficient evidence, he read
a multitude of writers, of various kinds. _In his twelfth year he
applied more particularly to the study of the fathers_, and
councils of the six first centuries, and began to make a regular
collection of their canons. He read every author in the original,
having discovered so much negligence or ignorance in most
translations, that he paid no regard to their authority.

Thus he continued his studies, neither drawn aside by pleasures nor
discouraged by difficulties. The greatest obstacle to his improvement
was want of books, with which his narrow fortune could not liberally
supply him; so that he was obliged to borrow the greatest part of
those which his studies required, and to return them when he had read
them, without being able to consult them occasionally, or to recur to
them when his memory should fail him.

It is observable, that neither his diligence, unintermitted as it was,
nor his want of books, a want of which he was, in the highest degree,
sensible, ever produced in him that asperity, which a long and recluse
life, without any circumstance of disquiet, frequently creates. He was
always gay, lively, and facetious; a temper which contributed much to
recommend his learning, and which some students, much superiour in
age, would consult their ease, their reputation, and their interest,
by copying from him.

In the year 1735 he published Anti-Artemonius; sive, initium evangelii
S. Joannis adversus Artemonium vindicatum; and attained such a degree
of reputation, that not only the publick, but _princes, who are
commonly the last_ by whom merit is distinguished, began to
interest themselves in his success; for, the same year, the king of
Prussia, who had heard of his early advances in literature, on account
of a scheme for discovering the longitude, which had been sent to the
Royal society of Berlin, and which was transmitted afterwards by him
to Paris and London, engaged to take care of his fortune, having
received further proofs of his abilities at his own court.
