This notebook was used by Clarence B. Fargo at the American Graphophone Co.\'s plant in Bridgeport, Connecticut, during the period 1894-1896 for notes on chemical analyses of wax phonograph cylinders.

There are also some of Fargo\'s own accounts from the period 1891-1894 and various recipes for drug prescriptions.
