Dear Sir

an hour after my last Letter went one came from y^r friend M^r Low of Orkney which pleased me much he offers his service freely & I dare say it will be of vast use. he speaks of a treatise of his that is soon to reach you. he permits me to have any extracts which I shall be happy to have when it reaches you. Inclose a Letter which I beg you would give my friend M^r Jackson of the Post office begging it may be sent by the first opportunity. if M^r Lows treatise is worth publishing I shall assist cheerfull [sic].

I am D^r Sir
Truely y^rs

Dec^r 24^th. 1772

Pray let me know how the post goes to the Orknies, & when this sets out.
