CHAP. XII. Of the use of the Magnet in this Art.
IF thou hast never so good a Magnet, and knowest not the use of it, thou bestowest thy labour in vain. We shall therefore add the use of it, that nothing may be wanting in this Art; And about it, being most needful, and asking little labour, there needs but few words: yet one thing is to be noted in the way; namely, That al∣though the aforesaid beams do alwayes flow from the bo∣die, yet there are some parts out of which they flow more copiously: in one word, they are the Emmunctories by which the body is as it were cleansed, and the spirit doth accompany the superfluities; because these parts are more porous and spungie, it wandreth out more freely, finding a larger egresse.
Now come we to the use of the Magnet: Apply the Magnet to the emmunctory of the part grieved, and procu∣ring the patient to sweat, which is best done by some Cordial Diaphoretick fitting the disease, leave there the Mag∣net until it be impregnate with the vital spirit, then re∣move it, and immediatly use it according to the precepts given in the Chapter of Transplantation: but take heed it be speedily done, for fear the spirit be dissipated by some external more powerful cause; for then Transplantation will be in vain attempted: if the patient be not cured at the first, do it again, and thou shalt see the desired effect.
And not only diseases are cured this way, but strange things, even all that are done by transplantation, are this way effected: although transplantation may be done by other means, as shall be shewed by and by. But if thou desire by this means to transplant diseases, read diligently the Chapter of Transplantation, and observe well the pre∣cepts there given, lest if things shall happen not to hit thy desire, thy ignorance do return to the reproach of this Art.
