I thank you for the Nautical almanacs, and for the two small tracts sent me since. it is only when science is contracted into the volume of a nutshell, as in these tracts, that I can indulge myself with a look into it. having no means of sending the fractional sum of 2. D 50 c the cost of the Nautical almanacs, I inclose a 5. D. bill which will pay for them & for those of the years 9. & 10. which you say can be had either of the English or American editions, & which I will therefore pray you to forward to me at your convenience. Accept my friendly salutations & assurances of great esteem & respect.
