But if ever any pursuit was more open to fraudulent practices than another, surely the pretended possession of a transmuting powder or elixir afforded a grand arena for their exercise. In this enlightened age, although we cannot fail to look with charity on the arduous labours of those adepts who honestly mixed devotional exercises with laborious experimental operations, selecting times and seasons for their alchemical work, and noting with accuracy the hours and days of fusions, sublimations, distillations, lixiviations, and so forth; still, it is scarcely possible to refrain from smiling at the docile simplicity of Ashmole in denouncing a certain class of Alchemists, as pretended masters and adepts, seeing "they are mere practisers of legerdemain," while he himself gave credence to the story of the warming-pan, already named as being shown to Queen Elizabeth, which was clearly a flagrant piece of fraud practised by Kelly, a common adventurer, and from his youth remarkable only for his indifferent character. An easily performed trick was effected by means of nails, or other light articles, made half of gold and half iron, but disguised, so as to appear to be of one metal and colour. Sometimes these knaves employed crucibles, having an interior false bottom, below which a small quantity of gold was placed, which, being reproduced, as was pretended from base materials, was offered as an example of success. Or, by having the gold in a hollow rod, stopped at one end with wax, used to stir up the materials, the gold would naturally enough appear in the crucible. Or, their materials being conveyed into charcoal, a similar result would be obtained on heating the crucible in a furnace. At other times, by the employment of amalgams, or solutions in acids, they could perform a species of electro-plating on common metals. The extent to which these nefarious practices were carried might appear incredible, considering the evident inconsistency of the owner of the pretended golden key to countless wealth, being in such comparative poverty as to be indebted to any one of moderate means for pecuniary assistance. But, it is some apology for such credulity when we call to mind the state of public morals, of education, of political institutions, and the prevalent superstition, not only among common people, but also the higher classes of all countries and creeds, down to the seventeenth century: representing a phase of the human mind, liable to be overawed by impostors, who boldly claimed supernatural aid in abetting their impositions. And the trickery of the designing was further aided by the close secrecy adopted by the adepts in their processes, their conversations, and their writings. Ashmole freely admits that--"Their chief study was to wrap up their secrets in fables, and spin out their fancies in 'vailes' and shadows, whose radii seem to extend every way, yet so that all meet in a common centre, and point only to one thing."
