The postcard is a brief communication from Dr. Charles Gatchell, a homeopath then on the faculty of the Homeopathic College of Medicine at the University of Michigan in Ann Arbor to Thomas Bradford. Bradford was the librarian and historian at the Homeopathic Medical College of Pennsylvania (later Hahnemann). The note includes a mention of Dr. H.C. (Henry Clay) Aldrich, who was also a member of the faculty at Michigan and subsequently became the President of the Minnesota State Homeopathic Institute. The correspondence refers to an idea that Gatchell and Bradford were hoping Aldrich would support. The note states that he would put it "before the faculty." Additional material by and about Dr. Gatchell, including other correspondence with Thomas Bradford, is found in Biographies of Homeopathic Physicians, compiled by Bradford.
