In 1784 some part of the quarries was broken through from above, and as there was imminent danger of the houses in the streets falling into ruin from similar accidents, a number of the most skilful engineers were ordered by the government to descend into the quarries, make a careful investigation, and render them in future altogether secure. While so engaged, M. Lenoir, lieutenant general of the police, conceived the idea of removing to the vaults the remains that had been buried in the cemetery of the Innocents, then standing on the present site of the Halles Centrales, the principal market of the city. Other graveyards within the municipal limits needed to be emptied, and it was determined that the contents of these graves should also be transferred to the subterranean region; so, on the 7th of April, 1786, a formal consecration of the Catacombs as a place of burial took place with imposing religious rites and ceremonies. The human bones were borne from the graves at night in funeral cars, accompanied by priests decked in their sacerdotal robes, carrying torches, swinging censers, and chanting the Roman Catholic service for the dead, and on arriving at the depository were hurled down a shaft in magnificently miscellaneous confusion. Such a democratic mixture, osseously speaking, of saints and sinners, princes and peasants, reformers and robbers, bishops and beggars, poets and pickpockets, grand ladies and grisettes, coquettes and cocottes, was never before made on the banks of the Seine. This superb disorder remains to the present day, so far as rank and caste are concerned. The skull of a pious prelate rests upon the ribs of a desperate cutthroat, and the thigh-bone of a once renowned beauty of the Faubourg St. Germain touches the grinning teeth of a vulgar conscript shot for desertion. The skeleton arms of a dainty poet are interlocked with those of a hideous hag who poisoned her father and mother in the Rue de la Croix Rouge. [Sidenote: A BONY CONFUSION.]
