66. Blood is stanched divers ways. First, by the inquisition; both for use and disclosure of astringents, and repercussive medicines. Second causes. For heat and cold are nature's two hands, ly, by drawing of the spirits and blood inwards, whereby she chiefly worketh; and heat we have which is done by cold, as iron or a stone laid to in readiness, in respect of the fire; but for cold the neck doth stanch the bleeding of the nose; we must stay till it cometh, or seek it in deep also it hath been tried, that the testicles being put caves, or high mountains : and when all is done, we cannot obtain it in any great degree: for driving away of spirits such as have some degree furnaces of fire are far hotter than a summer's of heat: for the banishing of the heat must needs sun; but vaults or hills are not much colder than leave any body cold.

The first means of producing cold, is that of living creatures: and it were not amiss to try which nature presenteth us withal: namely, the opium, by laying it upon the top of a weatherexpiring of cold out of the inward parts of the glass, to see whether it will contract the air; but earth in winter, when the sun hath no power to i doubt it will not succeed; for besides that the overcome it; the earth being, as hath been noted virtue of opium will hardly penetrate through by some, - primum frigidum."

The second cause of cold is the contact of were not amiss therefore to try it, with warm cold bodies; for cold is active and transitive into waters; the one exposed to the beams of the bodies adjacent, as well as heat: which is seen moon, the other with some screen betwixt the in those things that are touched with snow or beams of the moon and the water, as we use to cold water.

It is reported by one of the ancients, that We see nitre, which hath a quick spirit, is cold; in Lydia, near Pergamus, there were certain more cold to the tongue than a stone; so water workmen in time of wars fled into caves; and is colder than oil, because it hath a quicker spirit: the mouth of the caves being stopped by the for all oil, though it hath the tangible parts bet- enemies, they were famished. But long time ter digested than water, yet hath it a duller spirit: after the dead bones were found; and some 80 snow is colder than water, because it hath vessels which they had carried with them; and more spirit within it: so we see that salt put to the vessels full of water; and that water thicker, ice, as in the producing of artificial ice, increaseth and more towards ice, than common water: which the activity of cold: so some “insecta,” which is a notable instance of condensation and indurahave spirit of life, as snakes and silk-worms, are tion by burial under earth, in caves, for long time: to the touch cold: so quicksilver is the coldest and of version also, as it should seem, of air into of metals, because it is fullest of spirit.
