Summary:

Apologizes for not acknowledging JH's work. Asks for copy of Royal Geographical Society's papers. Discusses [François] Arago's work on light beams and prisms. Requests JH's opinion concerning [Wilhelm] Klinkerfues's theory of light, which seems to make [Augustin] Fresnel's hypothesis superfluous.
