I have lately seen a collection of Drawings, without doubt, the finest in Europe, for the method and number of rare designs; nor is the price, considering the true value, at all too much. Mr. Envoy is of the same opinion, and has desired me to let an abstract of my catalogue, which I am making with all exactness, be copied out, to send to my Lord President. I send an abstract with this post, as I have done to Mr. Topham.
