Summary:

Learned of John Gorrie's mechanical ice-making method. Asks CM to send letter to JH recounting conversation of 11 Feb. 1848 in which JH told CM about JH's theory for making ice by compressing air. JH does not want to interfere with Gorrie's claim, but will submit CM's letter to Athenaeum and put on record, for sake of 'scientific history,' that JH was 'certain' that such a principle would work. Condolences for death of CM's partner.
