Having been lately a good deal out of health, & the Chief Clerk confined by the same cause for some days past, several letters have been unavoidably unanswerd, & among them yours asking the aid of the Dept. of State in exchanging scientific information with a Correspondent in Europe.1 You will now please to accept the information that whatever facility can be properly afforded for the purpose will readily be so, and particularly that of transmitting your letters in the manner you suggest. With great respect & esteem I am Dear Sir Your obedt. servt.
