in the road a newly-erected fountain, and even distinguished an inscription upon it, namely—"If any man thirst let him come unto me and drink." Some time afterwards, she mentioned the fact with pleasure to the daughters of a gentleman who was supposed to have erected it. They expressed their surprise at her statement, and assured her that she must be quite mistaken. Perplexed with the contradiction between the testimony of her senses and of those who would have been aware of the fact had it been true, and feeling that she could not have been deceived (" for seeing is believing "), she repaired to the spot, and found to her astonishment that no drinking-fountain was in existence—only a few scattered stones, which had formed the foundation upon which the suggestion of an expectant imagination had built the superstructure. The subject having previously occupied her attention, these sufficed to form, not only a definite erection, but one inscribed by an appropriate motto corresponding to the leading idea.'"(1)

We may give as another illustration an illusion which presented itself to Sir Walter Scott(2) He had been reading, shortly after the death of Lord Byron, an account in a publication professing to detail the habits and opinions of the poet. As Scott had been intimate with Lord Byron he was deeply interested in the publication, which contained some particulars relative to himself and other friends. "Their sitting-room opened into an entrance hall, rather fantastically fitted up with articles of armour, skins of wild animals, and the like. It was when laying down his book,

and passing into this hall, through which the moon was beginning to shine, that the individual of whom I speak saw, right before him, and in a standing posture, the exact representation of his departed friend whose recollection had been so strongly brought to his imagination. He stopped for a single moment, so as to notice the wonderful accuracy with which fancy had impressed upon the bodily eye the peculiarities of dress and posture of the illustrious poet. Sensible, however, of the delusion, he felt no sentiment save that of wonder at the extraordinary accuracy of the resemblance, and stepped onward towards the figure, which resolved itself, as he approached, into the various materials of which it was composed. These were merely a screen, occupied by great-coats, shawls, plaids and such other articles as usually are found in a country entrance-hall. The spectator returned to the spot from which he had seen the illusion, and endeavoured, with all his power, to recall the image which had been so singularly vivid. But this was beyond his capacity," &C.1 Although Sir Walter Scott might be sensible of the delusion, it may be more than doubted whether, in the first century of our era, such an apparition proceeding from or connected with religious agitation of mind would have been considered so.

Dr. Abercrombie(2) mentions many instances of spectral illusions, "some of the most authentic facts" relating to which he classes under the head of "intense mental conceptions so strongly impressed upon the mind as, for the moment, to be believed to have a real existence."

We cannot, however, venture to quote illustrations.(1) Dr. Hibbert, in whose work on Apparitions many interesting instances are to be found, thus concludes his consideration of the conditions which lead to such illusions: "I have at length concluded my observations on what may be considered as the leading mental laws which are connected with the origin of spectral impressions. The general inference to be drawn from them is,—that Apparitions are nothing more than morbid symptoms, which are indicative of an intense excitement of the renovated feelings of the mind."(2) Subjective visions, believed to have had objective reality, abound in the history of the world. They are familiar to all who have read the lives of the Saints, and they have accompanied the progress of Christianity in various forms from the trances of Montanism to the vision of the "Immaculate Conception" in the Grotto of Lourdes.

If we turn to the inquiry whether a similar subjective impression can be received by many persons at one time and be mistaken by them for an objective reality, an equally certain reply in the affirmative must unhesitatingly be given. The contagiousness of emotion is well known,(3) and the rapidity with which panic, for instance, spreads from a single individual to the mass is remarked every day. The most trifling incident, unseen by more than a few and, therefore, more pliant in the imagination
