EV. Your curiosities eclipse mine, Ida. But the natural _leaning to the marvellous_, will, without mania or fanaticism, by the mere sympathy of intercommunicating minds, spread wide these illusions, even in the most simple instances. Some time since, a very large assemblage were watching with intense interest the stone lion of the Percies, at Northumberland House. They were unanimous in the conviction that he was swinging his tail to and fro; a false impression, of course, which had gradually accumulated from this solitary exclamation of a passenger: “By heaven, he wags his tail!” Of this sort of illusion I was myself a witness. Beneath the western portico of St. Paul’s, a crowd of gazers were bending their eyes on the image of the saint, who was nodding at them with a very gracious affability. Curiosity had risen to the pitch of wonder at a miracle, when suddenly a sparrow-hawk flew from the ringlets of the saint, and the illusion vanished. These eccentricities, you will perceive, occurred _spontaneously_; and it is a most interesting study to note the analogies between _these_ diseased actions, and _those_ resulting from the influence of certain gases and vegetable juices. I have known the seeds of _stramonium_, when swallowed by children, produce a temporary delirium, and a state of _chorea_, singing, dancing, laughing, and other mad frolics, which could not be controlled. And in the “History of Virginia,” by Beverly, it is recorded, that during the rebellion of Bacon, at James Town, some soldiers, after eating the young leaves of _stramonium_ for spinach, enacted “a very pleasant comedy, for they turned natural fools upon it for several days. One would blow up a feather into the air, another would dart straws at it with much fury, another, stark naked, was seen sitting up in a corner, like a monkey, grinning and making mouths.” In this frantic condition they were confined for safety. In eleven days they recovered, but had no memory of the delirium. Such also is the effect of large quantities of black henbane. Dr. Patouillet, of Toucy, in France, in 1737 witnessed a mania of this sort in nine persons, who had eaten of that root. It was marked by the strangest actions and expressions. In these also there was no recollection of the illusion.
