CHAP. XXXVIII. Of Quick-silver.
QUick-silver is so called because it resembleth silver in the colour, and is in * 1.1 perpetuall motion, as if it had a spirit or living soule. There is a great controversie amongst authors concerning it. For most of them affirme it * 1.2 hot, amongst whom is Galen, Halyabas, Rhases, Aristotle, Constantine, I∣sack, Platearius, Nicholas Massa: they maintain their opinion by an argument drawn from things helping and hurting; besides from this, that it is of such subtle parts, that it penetrates, dissolves, and performeth all the actions of heate upon dense and hard mettals; to wit, it attenuateth, incideth, dryeth, causeth salivation by the mouth, purgeth by the stoole, moveth urine and sweat over all the body, neither doth it stirre up the thinner humours onely, but in like sort the grosse, tough and viscous, as those which have the Lues Venerea find by experience, using it either in ointments or plasters.
Others affirme it very cold and moyst, for that put into emplasters and so apply∣ed, it asswageth paine by stupefaction, hindring the acrimony of pustles and chole∣rick inflammations. But by its humidity it softeneth scirrhous tumours, dissolveth and dissipateth knots and tophous knobs; besides, it causeth the breath of such as are anointed therewith to stinke, by no other reason, than that it putrefies the obvious humours by its great humidity. Avicens experiment confirmes this opinion, who affirmeth, that the bloud of an Ape that drunke Quicksilver, was found concrete a∣bout the heart, the carcasse being opened. Mathiolus, moved by these reasons, writes * 1.3 that Quicksilver killeth men by the excessive cold and humide quality, if taken in a∣ny large quantity, because it congeales the bloud and vitall spirits, and at length the very substance of the heart, as may bee understood by the history of a cetaine Apo∣thecary, * 1.4 set downe by Conciliator; who, for to quench his feaverish heat, in stead of water, drunke off a glasse of Quicksilver, for that came first to his hands: hee dyed within a few houres after, but first hee evacuated a good quantity of the Quicksilver by stoole, the residue was found in his stomack being opened, and that to the weight of one pound; besides, the bloud was found concrete about his heart. Others use another argument to prove it cold, and that is drawne from the composition there∣of, because it consists of lead and other cold mettals. But this argument is very weak. For unquencht Lime is made of flints and stony matter, which is cold, yet neverthe∣lesse it exceeds in heat. Paracelsus affirmeth that quicksilver is hot in the interior sub∣stance, * 1.5 but cold in the exterior, that is, cold as it comes forth of the mine. But that coldnesse to bee lost as it is prepared by art, and heat onely to appeare and bee left therein, so that it may serve in stead of a tincture in the transmutation of mettals. And verily it is taken for a rule amongst Chymists, that all metals are outwardly cold, by reason of the watery substance that is predominant in them, but that inwardly they are very hot, which then appeares when as the coldnesse together with the moy∣sture is segregated, for by calcination they become caustick. Moreover many ac∣count quicksilver poyson, yet experience denyes it. For Marianus Sanctus Barali∣tanus * 1.6 tels that hee saw a woman, who for certaine causes and affects, would at seve∣rall times drink one pound and an halfe of quicksilver, which came from her againe by stoole without any harme. Moreover he affirmeth that hee hath knowne sundry who in a desperate Cholick (which they commonly call miserere mei) have beene freed from imminent death, by drinking three pounds of quicksilver with water on∣ly. For by the weight it opens and unfolds the twined or bound up gut, and thrusts forth the hard and stopping excrements; he addeth that others have found this me∣dicine
