You'l receive ye 2d Book on Thursday night or Friday by ye Coach. I have directed it to be left wth Mr Hunt at Gresha{illeg}|m| Coll. Pray let me beg ye favour of a line or two to know of ye receipt. I am obliged to you for pushing on ye edition because of peoples expectation, thô otherwise I could be as well satisfied to let it rest a year or two longer. Tis a double favour that you are pleased to double your pains about it. Dr Wallis's papers may be long & I would not give you ye trouble of transcribing them all. The heads may suffice. The resistence in swift motions is in a duplicate proportion to ye celerity. The deduction of ye Suns Parallax from ye Moons variation I cannot promise now to consider. When Astronomers have examined whether there be such an inequality of her motion in ye Quadratures as I meti|n|tioned in my last & determined ye quantity ther{illeg}|e|of, I may take some occasion perhaps to tell them ye reason. No more at prsent from

Yor most affectionate humble
