I have recd. your favor with the accompanying Copies of your Report on Weights & Measures, & I have forwarded the two, one for Professor Patterson, & one for the University of Virginia; and shall dispose of the others as you desire. For the Copy alloted to myself, I return you my thanks. The decrepit state of my health, added to my great age & other causes, have prevented me from looking much into the work. My confidence in your aptitude for it, takes the place of a positive proof of its merits.

I am glad to learn that you are to resume the important labour of surveying the Coast. I hope you will be able to compleat it; & to your own satisfaction, in which case I doubt not it will be to the satisfaction of those who invite you to the undertaking. I tender you Sir my esteem & my friendly salutations
