The river Adonis being impregnated, during certain seasons, with volumes of dust raised from the red soil of that part of Mount Libanus near which it flows, gave rise to the fable of the periodical effusion of the blood of Adonis. There is a rock near the Island of Corfu, which bears the resemblance of a ship under sail: the ancients adapted the story to the phenomenon, and recognised in it the Phenician ship, in which Ulysses returned to his country, converted into stone by Neptune, for having carried away the slayer of his son Polyphemus. A more extensive acquaintance with the ocean, has shown that this appearance is not unique; a similar one on the coast of Patagonia, has more than once deceived both French and English navigators; and rock Dunder, in the West Indies, bears a resemblance, at a distance equally illusive. There is another recorded by Captain Hardy, in his recent travels in Mexico, near the shore of California; and the "story of the flying Dutchman," is founded on a similar appearance at the Cape of Good Hope, connected with a tradition which has been long current there among the Dutch colonists. Another instance is afforded by the chimaera, the solution of which enigma, as given by Ovid, is so fully substantiated by the very intelligent British officer who surveyed the Caramania a few years since. Scylla the sea monster, which devoured six of the rowers of Ulysses, M. Salverte, a recent compiler on the marvellous, is tempted to regard as an overgrown polypus magnified by the optical power of poetry, though we are disposed to give the credit to an alligator, or its mate, a crocodile; and this occurrence is not so fictitiously represented, as it is supposed to be. MAGICAL PRETENSIONS OF CERTAIN HERBS, ETC. In the enumeration of plants possessing magical properties, Pliny mentions those which, according to Pythagoras, have the property of concealing water. Elsewhere, without having resource to magic, he assigns to hemp an analogous quality. According to him, the juice of this plant poured into water becomes suddenly inspissated and congealed. It is probable enough, that he indicated a species of mallow, the hemp-leaved marsh-mallow, of which the mucilaginous juice produces this effect to a certain point, and an effect which may also be obtained from every vegetable as rich in mucilage. Of vegetable productions, many produce intoxicating effects, such as berries of the night-shade,[132] scammony, and various species of fungi. These unquestionably have been made subservient to demonological purposes, which, with the ignorant, have passed off for supernatural agency. The priests, to whom the little comparative learning of the dark ages attached, knew well how to impose upon the credulous: but imposition was not always their object; an extent of benevolence prevailed which contemplated the relief of their fellow creatures afflicted with sickness.
