On one Sabbath-day, about six years ago, a congregation had gathered together, as was their wont, for the celebration of divine worship, in the small country church of Turnham Green, near Chiswick. The officiating clergyman and the worshiping assembly had jointly gone through the liturgical services without the occurrence of any unusual event. As soon as the robed minister had ascended the sacred desk, and commenced his discourse, however, the eyes of a portion of the audience were attracted toward a gentleman occupying a somewhat conspicuous position in the church, whose strange and restless movements, wild and excited air, and occasional audible exclamations, indicated the presence of either a fanatic or a lunatic. These symptoms continued to increase, until, at length, as if irritated beyond endurance by some sentiment that fell from the lips of the preacher, he gave way to a perfect paroxysm of frenzy, under the influence of which he seized his hat, and flung it at the head of the minister. Of course, the service was suspended until the offender was expelled. It was soon discovered that the unhappy author of this untoward disturbance was suffering under a violent fit of mania. When borne from the church, no person could recognize or identify him. He was a total stranger to all residing in the neighborhood, so that no clew could be obtained that would enable them to restore him to the custody and surveillance of his friends. Under these circumstances, he was taken to the adjoining work-house at Isleworth, where he was detained for some weeks under medical care, during which period the most diligent inquiries were instituted with the view of unraveling the mystery of the stranger's kinship. But without avail. No one claimed him; and even when pressed himself to impart some information on the subject, he either could not or would not divulge the secret. Finding, at length, that all efforts to identify the great Incognito were ineffectual, he was removed to Hanwell, the asylum of the county to which he had thus suddenly become chargeable, and where he has ever since remained.
