In no age, says a popular writer, has the world been destitute of those who professed, by some instrumentality or other, to hold intercourse with departed spirits. Neither has any age been without its reputed spectres, ghosts, or apparitions. The high priest of the Buddhist and Hindoo temples, in former times, when arrayed in the consecrated garments for the festivals, wore a round knob, about the size of a large pendent drop of a chandelier, suspended from his neck by a chain of great value and of dazzling brilliancy. It was through the agency of this crystal that he was supposed to hold communion with the spirit or spirits to whom he and his followers accorded devotion and made intercessions; and the glass, acting as did the famed oracle of Delphi, gave orders and commands, and settled all great questions that might be submitted to its spiritual master. The priest, although he might be a pattern of purity, and the quintessence of all that was good, having, however, the sin of being in years, and not able, perhaps, to hide from the spirit inhabiting the crystal all the transactions of his youth, could not hold a direct communication with it. To arrange this, a certain number of boys, and sometimes, in some of the temples, young damsels, were retained, who, having never mixed with the world, could not be supposed to be in any way contaminated by its vices. These alone were said to be capable of beholding the spirit when he chose to make his appearance in the divining glass, and interpreting to and fro the questions put and answers received. Although it was not every boy or _seer_ to whom was permitted the gift of spiritual vision, yet in latter times, when divining crystals multiplied, little ragged boys would run after the passers in the streets, and offer to _see_ any thing that might be required of them, for a trifling gift, even a cake or sweetmeat. In Egypt, the divining glass is superseded by putting a blot of thick black fluid into the palm of a boy's hand, and commanding him to see various people and things; of which practice Lane, in his Modern Egyptians, gives some curious disclosures. Divining mirrors were not confined to the East. Dr. Dee was the first English impostor who vaunted the possession of one of these priceless treasures. He had for the _seer_ one Keily, an Irishman; and to this, doubtless, was attributable the impression that prevailed among the astrologers and amateur spirit hunters, that when the spirits condescended to speak, they always gave speech with a very strong spice of the brogue. This "beryl," as it is called, was preserved among the Strawberry Hill curiosities, and fell under the hammer of George Robbins at the memorable sale. It proved to be a globe of _cannel coal_. In Aubrey's Miscellany there is an engraving of another larger crystal, and there are with it many wonderful stories. Yet, notwithstanding the magic capabilities of these mirrors, they went out of fashion until the beginning of the year 1850.
