I have recieved the treatise describing the very ingenious Bathometer for sounding the depths of the sea, which you were so kind as to send me, and with it a model of the instrument itself. I pray you, Sir, to accept my thanks for this mark of your attention. our Nation, as a publick body, being at present engaged in no pursuit where the use of this ingenious machine could be employed, I have supposed I could not better answer your views, nor place it where it would be more likely to be of utility than by presenting it to the American Philosophical society at Philadelphia. I have therefore consigned it to that repository, together with the treatise, where, better than in any other place it’s value will be justly estimated, and it’s object be most likely to be brought into general notice.

Accept, I pray you, my salutations & assurances of respect.
