This acknowledges the Receipt of your Collection of philosophical Letters, and Dissertations in a quarto Volume which with your Letter came safe to hand last Summer. For which please to accept my Thanks. They have given me great Pleasure and Instruction.

Will you be so kind Sir as to procure them and deliver them to Peck, who will pay for them. I should not give you this Trouble, but that it may be difficult for him to find, especially the two last. The Rev. Samuel Lock of Sherburn is lately elected President of Harvard College in the Room of the late President Holyoke. Wishing you every Blessing I am Sir Your obliged Friend and most obedient Servant
