I think I have elsewhere stated in my definition of Benevolent Elementals that they would seem to be identical with the good fairies of our childhood's days, and with the angels in the Bible. In any case they are employed by the Higher Occult Powers friendly to man, and are always with us, trying to keep us in the paths of virtue, and guarding us from physical danger.
Vice Elementals, on the other hand, are employed by the Higher Occult Powers inimical to man, and are also always with us, trying to persuade us to do everything that harms us mentally, morally, and physically, and that, in a like manner, indirectly injures our neighbours.
Vice Elementals appear in every variety of form, from beautiful, captivating women and handsome, insinuating men, to the grossest and most terrifying caricatures of both man and beast; for example, pig-headed men, monstrous dogs (such as "The Mauthe Dog" of Peel Castle, Isle of Man; the Kirk-grim of Scandinavia, which is sometimes a dog and sometimes a horse or pig); the Gwyllgi of Wales; huge bears (such as the famous "bear" ghost of the Tower of London), and many other mal-shaped forms of man and beast.
Whereas, however, the more prepossessing type of this class of Elemental roams everywhere, the more terrible are usually confined to places where crimes have been committed and impure thoughts conceived.
VAGRARIANS.
These Elementals, which I have already described, are merely survivals of experiments at life, prior to the selection of any definite forms of man and beast; they were created by the neutral Powers, and their attitude to man (whom they shun as much as possible), though spiteful and mischievous, is prompted by nothing actually sinister.
MORBAS, OR DISEASE ELEMENTALS.
These Phantasms are the Agents of the Evil Creative Powers. Always hideous in appearance, they create all manner of malignant bacilli, and are responsible for all diseases and illness, which they often delight in predicting.
CLANOGRIANS, OR FAMILY GHOSTS.
Why there should be a particular type of Elemental attached to certain families it is difficult to say. Some people think it is solely on account of the dreadful crimes perpetrated by members of these families in past days; but if that were the case, what family would be exempt, since there can be very few amongst us who could positively assert that no ancestor of his had ever committed a murder! I think it more likely, that, at one time, Man was in much closer touch with the Creative Powers than he is now, and that certain families, as a mark of friendship, or otherwise, had Clanogrians attached to them (by both the Benevolent and Antagonistic Powers), with the express purpose of warning them of physical danger, and that in course of time, as the relationship between the Higher Powers and man grew more distant, the functions of these Family Elementals became fewer and fewer, until at length they consisted solely of Death warnings, as is now the case.
