I am very much oblig'd to you, Dear Sir, for the kind offers you make
in your friendly letter. I have desir'd already Mr Suard to bring over
a few books lately published in your metropolis. I am very glad to hear
that Gentleman is pleas'd with his journey.

There's no possibility of getting for you a compleat sett of Callots
engravings. Such a collection must be the business of many years; it
is to be found only after the decease of some curious men who have taken
a great deal of trouble to collect them. I found indeed in two shops 8
or 10 of them, but the proofs (les epreuves) were very indifferent and
they wanted to sell them excessively dear; in general 200 guineas would
procure a collection very far from being compleat.

My wife and all our common acquaintence desire their best compliments
to you and to Miss Wilkes and you know the sentiments wherewith I am
for ever
Dear Sir
your affectionate friend and
very humble servant
