I think, as a matter of fact, that apparitions can, whilst manifesting themselves to some, remain invisible to others, and that they themselves determine to whom they will appear. Some types of phantasms apparently prefer manifesting themselves to the spiritual or psychic-minded person, whilst other types do not discriminate, but appear to the spiritual and carnal-minded alike. There is just as much variety in the tastes and habits of phantasms as in the tastes and habits of human beings, and in the behaviour of both phantasm and human being, I regret to say, there is an equal and predominant amount of inconsistency. _Intuition_ I do not think it can be doubted that psychic people have the faculty of intuition far more highly developed than is the case with the more material-minded. "Second sight" is but another name for the psychic faculty, and it is generally acknowledged to be far more common among the Celts than the Anglo-Saxons. That this is so need not be wondered at, since the Irish and the Highlanders of Scotland (originally the same race) are far more spiritual-minded than the English (in whom commerciality and worldliness are innate), and consequently have, on the whole, a far greater attraction for spirits who would naturally prefer to reveal themselves to those in whom they would be the more likely to find something in common. There is still a belief in certain parts of the Hebrides that second sight was once obtained there through a practice called "The Taigheirm." This rite, which is said to have been last performed about the middle of the seventeenth century, consisted in roasting on a spit, before a slow fire, a number of black cats. As soon as one was dead another took its place, and the sacrifice was continued until the screeches of the tortured animals summoned from the occult world an enormous black cat, that promised to bestow as a perpetual heritage on the sacrificer and his family, the faculty of second sight, if he would desist from any further slaughter. The sacrificer joyfully closed with the bargain, and the ceremony concluded with much feasting and merriment, in which, however, it is highly improbable that the phantasms of the poor roasted "toms" took part. _Clairvoyance_ Clairvoyance is a branch of occultism in which I have had little experience, and can, therefore, only refer to in brief. When I was the Principal of a Preparatory School, I once had on my staff a Frenchman of the name of Deslys. On recommencing school after the Christmas vacation, M. Deslys surprised me very much by suddenly observing: "Mr O'Donnell, did you not stay during the holidays at No. ... The Crescent, Bath?" "Yes," I replied; "but how on earth do you know?" I had only been there two days, and had certainly never mentioned my visit either to him or to anyone acquainted with him.
