[78] As is the custom in the exploitation of proprietary medicines, the preparation which is the firm’s main output—the leader—is made to do duty as an advertising medium for auxiliary preparations. Thus the Angier Emulsion booklet advises the use of Angier’s Throat Tablets. These tablets are alleged to be composed essentially of elm bark and petroleum, are claimed to “promote appetite and aid digestion,” and it is stated that “their healing action on all mucous surfaces makes them decidedly beneficial, not only to the pulmonary tract but on the digestive areas as well.” Angier’s Throat Tablets were examined in the Association’s Laboratory to determine the amount and kind of petroleum present in the tablets. Extraction of the tablets with ether yielded a petroleum product which resembled in every way the product obtained from the emulsion. Slightly less than 12 per cent. of the tablet was composed of the petroleum oil. The part insoluble in ether appeared to consist essentially of elm bark, with gum and sugar.
