We will suppose ourselves standing in Cornhill, on a pleasant morning of the year 1670, about the hour when the shutters are unclosed, and the dust swept from the doorsteps, and when Business rubs its eyes, and begins to plod sleepily through the town. The street, instead of running between lofty and continuous piles of brick, is but partially lined with wooden buildings of various heights and architecture, in each of which the mercantile department is connected with the domicile, like the gingerbread and candy shops of an after-date. The signs have a singular appearance to a stranger's eye. These are not a barren record of names and occupations yellow letters on black boards, but images and hieroglyphics, sometimes typifying the principal commodity offered for sale, though generally intended to give an arbitrary designation to the establishment. Overlooking the bearded Saracens, the Indian Queens, and the wooden Bibles, let its direct our attention to the white post newly erected at the corner of the street, and surmounted by a gilded countenance which flashes in the early sunbeams like veritable gold. It is a bust of AEsculapius, evidently of the latest London manufacture; and from the door behind it steams forth a mingled smell of musk and assafaetida and other drugs of potent perfume, as if an appropriate sacrifice were just laid upon the altar of the medical deity. Five or six idle people are already collected, peeping curiously in at the glittering array of gallipots and phials, and deciphering the labels which tell their contents in the mysterious and imposing nomenclature of ancient physic. They are next attracted by the printed advertisement of a Panacea, promising life but one day short of eternity, and youth and health commensurate. An old man, his head as white as snow, totters in with a hasty clattering of his staff, and becomes the earliest purchaser, hoping that his wrinkles will disappear more swiftly than they gathered. The Doctor (so styled by courtesy) shows the upper half of his person behind the counter, and appears to be a slender and rather tall man; his features are difficult to describe, possessing nothing peculiar, except a flexibility to assume all characters it, turn, while his eye, shrewd, quick, and saucy, remains the same throughout. Whenever a customer enters the shop, if he desire a box of pills, he receives with them an equal number of hard, round, dry jokes,--or if a dose of salts, it is mingled with a portion of the salt of Attica,--or if some hot, Oriental drug, it is accompanied by a racy word or two that tingle on the mental palate,--all without the least additional cost. Then there are twistings of mouths which never lost their gravity before. As each purchaser retires, the spectators see a resemblance of his visage pass over that of the apothecary, in which all the ludicrous points are made most prominent, as if a magic looking-glass had caught the reflection, and were making sport with it.
