Letter from Joseph Henry, first Secretary of the Smithsonian Institution, to John Tyndall, a British physicist, November 6, 1872. In the letter, Henry states his desire for Tyndall to lecture in Baltimore, Maryland, as it is a city of great wealth but little exposure to the sciences. He also notes the importance Tyndall's lectures will have in Washington, DC, in regards to government appropriations.
