    agents, cures for both human and animal ailments, and recipes for varnishes, oils,
    and paints (Guildhall Library MS 16 262, by permission of the Guildhall Library,
    Corporation of London). The preface to a 1875 Post Office Directory clarifies

    whale oil, &c.; the confectioner, the druggist, and the oilman have now branched
    off into separate and distinct trades" (The 1875 post office directory of the grocery
    and oil and color trades. 18 75, iv).
