Nor are the deceits of the base nostrum-mongers for making the hair grow and curl, or for making the bald pericranium of a nonagenarian vegetate in all the luxuriance of rejuvenization, the only frauds practised: equally destructive are the advertised depilatories, the general basis of which is yellow orpiment, a certain poison if taken inwardly. It is true that the Turks, with whom bald heads are in fashion, and also the Chinese, do use this as an unguent, to save the trouble of frequent shaving; but it should be recollected that those cosmetics which may be harmless on the head of a robust Janissary,—of a bashaw of three tails or a fat Mandarin, do not necessarily become fit adjuncts for the toilette of a “British fair,”—“the lovely daughters of Albion, Erin, or Scotia,” or even that of an “Herculean delicate,” a Lilliputian dandy, or a Bond-street exquisite. Snuff-sniffers and tobacco-munchers and puffers, do ye know what the delectable ingredients which form part of the articles of your recreation, are? Have you never heard that snuff is often compounded of pulverised nut-shells, of the powder of old rotten wood, called powder post; that the colour is improved by ochre, and the appearance and feel modified by an addition of treacle or urine? And have you never been told that the pungency of snuff is increased by the agency of powdered glass or the muriate of ammonia? Tobacco smokers and “_chawers_,” have ye never been told that your favourite “_quid_” is often composed of black hellebore, corrosive sublimate, dried dock-leaves, and a variety of other _innocent_ ingredients? Oh, dear! what a deal you have yet to learn before you “become wise as serpents!” SECTION VIII.
