From John Marshall, 28 Sept. 1826
I am satisfied from the enqueries my friends have made for me that The Calm Observer, if ever published in a pamphlet, is no longer to be found in that form. Mr Hopkinson was kind enough to make the enquiry for me and to communicate the result. In my answer acknowledging the receipt of his letter I requested him to look into the files of the Aurora & to let me know the date of the first & of the last number. He has never noticed this letter, & I have suspect1 that it has miscarried.
