But the former were manufactured partly of white Cornish clay, with a portion of sugar only, with ginger and Guinea pepper. I was likewise informed, that of Tolu lozenges, peppermint lozenges, and ginger pearls, and several other sorts or lozenges, two kinds were kept; that the _reduced_ prices, as they were called, were manufactured for those very clever persons in their own conceit, who are fond of haggling, and insist on buying better bargains than other people, shutting their eyes to the defects of an article, so that they can enjoy the delight of getting it cheap: and, secondly, for those persons, who being but bad paymasters, yet as the manufacturer, for his own credit’s sake, cannot charge more than the usual price of the article, he thinks himself therefore authorized to adulterate it in value, to make up for the risk he runs, and the long credit he must give.’” (P. 332, 333.) Well—there is then some honesty left in the world. What a pleasure it is to have to deal with a _respectable_ man. But we return to the practices of the _knaves_. Olive oil “is sometimes contaminated with lead.” (P. 334.) The dealers in this commodity assert that lead or pewter “prevents the oil from becoming rancid. And hence some retailers often suffer a pewter measure to remain immersed in the oil.” (P. 336.) “The beverage called soda water is frequently contaminated both with copper and lead.” (P. 351.) Mr. Johnston, of Greek Street, Soho, was the first who pointed out the danger to the public. “Many kinds of viands are frequently impregnated with copper, in consequence of the employment of cooking utensels made of that metal. By the use of such vessels in dressing food, we are daily liable to be poisoned.” (P. 352.) “Mr. Thiery, who wrote a thesis on the noxious quality of copper, observes that ‘our food receives its quantity of poison, in the kitchen by the use of copper pans and dishes. The brewer mingles poison in our beer, by boiling it in copper vessels. The sugar-baker employs copper pans. The pastry-cook bakes our tarts in copper moulds. The confectioner uses copper vessels. The oilman boils his pickles in copper or brass vessels, and verdigrise is plentifully formed by the action of the vinegar upon the metal.’” (P. 353, 354.) Moreover, “various kinds of food, used in domestic economy, are liable to become impregnated with lead.” (P. 359.) Mr. Accum, speaking on the subject of Beer, says, “It will be noticed that some of the sophistications are comparatively harmless, whilst others are affected by substances deleterious to health.” (P. 185.)
