At left is a large crock used to ship chemicals for druggists. This crock contained bulk alcohol, and came from Henry K. Wampole and Company, in Perth, Ontario. At right is an early fire extinguisher from Champion's drugstore. Its fire retardant foam was produced by a reaction between baking soda and acid, initiated by the breaking of a glass stopper which separated the elements. (Alan Champion, photo by Tom MacDonald)
