The collection consists of two letters written by Michael Faraday, English physicist and resident of the Royal Institution of Great Britain, toward the end of his life. One is addressed to the Duchess of Northumberland thanking her for her generosity, and asking if she might send Faraday something in return, apparently a photograph of herself. The other letter is written to F. Gye, also thanking him for a gift, most likely tickets to a Covent Garden show: Frederick Gye was the prominent manager for the Royal Italian Opera productions. Acquired as part of the History of Medicine Collections at Duke University.
