even deprived of his reason, and a melancholic humor attacking his whole body, he became utterly insane, and, in the very house of his master, next the Church of St. James, committed suicide, by hanging himself with a rope." [Footnote: The passage from Didymus is this: "Macilenti et melancholici, qui binas pupillas in oculis habent, aut in uno oculo geminam pupillam, in altero effigiem equi,--quique oculos concavos ac veluti quibusdam quasi foveis reconditos gerunt, exhaustoque adeo universo humore ut ossa,--quibus palpebræ coherent, eminere, hirquique sordibus scatere cernuntur,--quibus in tota cute quæ faciem obducit squallor et situs immoderatus conspicitur, facillime fascinant. Strabones, glaucos, micantes et terribiles oculos habentes quæcumque et iratis oculis aspiciunt fascino inficiunt. Et _ego_ hisce oculis Romæ quondam Hispanum genere vidi, quem nominare non licet, qui cum truculentis oculis tetro et irato vultu servum ob nescio quod objurgâsset, adeo servus ille timore ac terrore perterritus fuit, ut non modo fascino affectus, sed rationis usu privatus fuerit, et melancholico humore totum ejus corpus invadente, ita ad insaniam redactus fuit, ut in domo sui heri prope ecclesiam Divi Jacobi sibi mortem consciverit et laqueo vitam finiverit."] _Moral_.--If you ever meet with such an agreeable person as this Spaniard appears to have been,--look out! In this connection, the reader will recall the similar power of Vathek, in Beckford's romance, who killed with his eye,--and the story of Racine, whom a look of Louis XIV. sent to his grave. The famous Albertus Magnus, master of medicine and magic, devotes a long chapter to the subject of eyes, giving us, at length, descriptions of those which we may trust and those which we must fear, some of them terrible and vigorous enough. From among them I select the following:--"Those who have hollow eyes are noted for evil; and the larger and moister they are, the more they indicate envy. The same eyes, when dry, show the possessors to be faithless, traitorous, and sacrilegious; and if these eyes are also yellow and cold, they argue insanity. For hollow eyes are the sign of craft and malignity; and if they are wanting in darkness, they also show foolishness. But if the eyes are too hollow, and of medium size, dry and rigid,--if, besides this, they have broad, overhanging eyebrows, and livid and pallid circles round them, they indicate impudence and malignity." [Footnote: Albertus Magnus, _De Animâ_.] If this be not enough to enable you, O my reader, to recognise the Evil Eye at sight, let me refer you to the whole chapter, where you will find ample and very curious rules laid down, showing a singular acuteness of observation.
