Your favor of the 6th. has been recieved, and I should with pleasure have lent my aid to promote a good engraving of Dr. Priestly had Mr Stewart been here as you expected. indeed his portraits are so fine that I should be sorry that the engraving should be from any other. but he is now at Boston, & I do not think there is any reason to expect him here. it is probable, if you have a correspondent there, that you may obtain either the original or a copy. for I am satisfied you need be under no apprehension of the former having been disposed of. accept my salutations & assurances of respect.
