Hume does not appear to have troubled himself about the matter, and does not even think it worth mention in _My Own Life_.
In 1756 he tells Clephane that he is worth L1,600 sterling, and consequently master of an income which must have been wealth to a man of his frugal habits.

In the same year, he published the second volume of the _History_, which met with a much better reception than the first; and, in 1757, one of his most remarkable works, the _Natural History of Religion_, appeared.

In the same year, he resigned his office of librarian to the Faculty of Advocates, and he projected removal to London, probably to superintend the publication of the additional volume of the _History_.
"I shall certainly be in London next summer; and probably to remain there during life: at least, if I can settle myself to my mind, which I beg you to have an eye to.

A room in a sober discreet family, who would not be averse to admit a sober, discreet, virtuous, regular, quiet, goodnatured man of a bad character--such a room, I say, would suit me extremely."[11] The promised visit took place in the latter part of the year 1758, and he remained in the metropolis for the greater part of 1759.

The two volumes of the _History of England under the House of Tudor_ were published in London, shortly after Hume's return to Edinburgh; and, according to his own account, they raised almost as great a clamour as the first two had done.
Busily occupied with the continuation of his historical labours, Hume remained in Edinburgh until 1763; when, at the request of Lord Hertford, who was going as ambassador to France, he was appointed to the embassy; with the promise of the secretaryship, and, in the meanwhile, performing the duties of that office.
