I must not conclude these brief notes without some reference to the medical theory of the medicinal efficacy of words. The EBERS papyrus already mentioned gives various formulas which must be pronounced when preparing and when administering a drug; and there is a draught used by the Eastern Jews as a cure for bronchial complaints prepared by writing certain words on a plate, washing them off with wine, and adding three grains of a citron which has been used at the Tabernacle festival. But enough for our present excursion; we must hie us back to the modern world, with its alkaloids, serums, and anti-toxins--another day we will, perhaps, wander again down the by-paths of Medicinal Magic. NOTE ON THE PARACELSIAN DOCTRINE OF THE MICROCOSM "Man's nature," writes CORNELIUS AGRIPPA, "_is the most complete Image of the whole Universe_."(1) This theory, especially connected with the name of PARACELSUS, is worthy of more than passing reference; but as the consideration of it leads us from medicine to metaphysics, I have thought it preferable to deal with the subject in a note. (1) H. C. AGRIPPA: _Occult Philosophy_, bk. i. chap. xxxiii. (WHITEHEAD'S edition, p. 111). Man, taught the old mystical philosophers, is threefold in nature, consisting of spirit, soul, and body. The Paracelsian mercury, sulphur, and salt were the mineral analogues of these. "As to the Spirit," writes VALENTINE WEIGEL (1533--1588), a disciple of PARACELSUS, "we are of God, move in God, and live in God, and are nourished of God. Hence God is in us and we are in God; God hath put and placed Himself in us, and we are put and placed in God. As to the Soul, we are from the Firmament and Stars, we live and move therein, and are nourished thereof. Hence the Firmament with its astralic virtues and operations is in us, and we in it. The Firmament is put and placed in us, and we are put and placed in the Firmament. As to the Body, we are of the elements, we move and live therein, and are nourished of them:--hence the elements are in us, and we in them. The elements, by the slime, are put and placed in us, and we are put and placed in them."(1) Or, to quote from PARACELSUS himself, in his _Hermetic Astronomy_ he writes: "God took the body out of which He built up man from those things which He created from nothingness into something... Hence man is now a microcosm, or a little world, because he is an extract from all the stars and planets of the whole firmament, from the earth and the elements, and so he is their quintessence.... But between the macrocosm and the microcosm this difference occurs, that the form, image, species, and substance of man are diverse therefrom. In man the earth is flesh, the water is blood, fire is the heat thereof, and air is the balsam. These properties have not been changed but only the substance of the body. So man is man, not a world, yet made from the world, made in the likeness, not of the world, but of God. Yet man
