Letter from Joseph Henry, first Secretary of the Smithsonian Institution, to J.H. Lefroy, a British scientist who studied magnetism, November 9, 1853. In the letter, Henry discusses the progress on Lefroy's Aurora-borealis memoir. He offers to send him research done by the Smithsonian in the past year concerning the topic, including observations made during the American Arctic Expedition. Henry includes his thoughts about the phenomenon, and his regrets that further collaboration and investigation could not have been conducted due to lack of funds.
