The principal source of information for this history of the Comstock medicine business comprises the records, letters, documents, and advertising matter found in the abandoned pill-factory building at Morristown, New York. Supplemental information was obtained from biographies, local and county histories, old city directories, genealogies, back files of newspapers, and materials from the office of the St. Lawrence County Historian, at the courthouse, Canton, New York. Two standard histories of the patent-medicine era in America are: Holbrook, Stewart H. _Golden Age of Quackery._ New York City: Macmillan Co. 1959. Young, J.H. _The Toadstool Millionaires, A Social History of Patent Medicines in America Before Federal Regulation._ Princeton University Press. 1961. Early in the present century, during the "exposure" of the patent-medicine industry, two principal critical works also were published, each highly specific and naming names fearlessly: Adams, Samuel Hopkins. _The Great American Fraud._ Serially in _Collier's_ Magazine in 1905-1906. (Reprinted in book form, 1906.) American Medical Association. _Nostrums and Quackery._ Chicago: American Medical Association Press. (Reprints from the _Journal of the American Medical Association_: volume I, 1911; volume II, 1921; volume III, 1936.) Recently two books have appeared, which are largely pictorial, essentially uncritical, and strive mainly to recapture the colorfulness and ingenuity of patent-medicine advertising. Carson, Gerald. _One for a Man, Two for a Horse._ 128 pages. New York City: Doubleday and Co. 1961. Hechtlinger, Adelaide. _The Great Patent Medicine Era._ New York City: Grosset and Dunlap. 1970. A highly recommended source of information on the very early history of patent medicines in America is: Griffenhagen, George B., and James Harvey Young. Old English Patent Medicines in America. _United States National Museum Bulletin 218, Contributions from the Museum of History and Technology_, paper 10: 155-183 1959. DR. MORSE'S PILLS LIVE ON
