is evil vapour and stinking. Therefore it freezeth not well at full. Hermes saith that lead in boiling undoeth the hardness of all sad and hard bodies, and also of the stone adamant. Aristotle speaketh of lead in the Meteorics and saith that lead without doubt when it is molten is as quicksilver, but it melteth not without heat, and then all that is molten seemeth red. Wonder it is that though lead be pale or brown, yet by burning or by refudation of vinegar oft it gendereth seemly colour and fair, as tewly, red, and such other; therewith women paint themselves for to seem fair of colour. The sapphire is a precious stone, and is blue in colour, most like to heaven in fair weather, and clear, and is best among precious stones, and most apt and able to fingers of kings. Its virtue is contrary to venom and quencheth it every deal. And if thou put an addercop in a box, and hold a very sapphire of Ind at the mouth of the box any while, by virtue thereof the addercop is overcome and dieth, as it were suddenly. And this same I have seen proved oft in many and divers places. Tin in fire departeth metals of divers kind, and it departeth lead and brass from gold and silver, and defendeth other metals in hot fire. And though brass and iron be most hard in kind, yet if they be in strong fire without tin, they burn and waste away. If brazen vessels be tinned, the tin abateth the venom of rust, and amendeth the savour. Also mirrors be tempered with tin, and white colour that is called Ceruse is made of tin, as it is made of lead. Aristotle saith that tin is compounded of good quicksilver and of evil brimstone. And these twain be not well medlied but in small parts compounded, therefore tin hath colour of silver but not the sadness thereof. In the book of Alchemy Hermes saith, that tin breaketh all metals and bodies that it is medlied with, and that for the great dryness of tin. And destroyeth in metal the kind that is obedient to hammer work. And if thou medliest quicksilver therewith, it withstandeth the crassing thereof and maketh it white, but afterward it maketh it black and defileth it. Also there it is said that burnt tin gendereth red colour, as lead doth; and if the fire be strong, the first matter of tin cometh soon again. Also though tin be more nesh than silver, and more hard than lead, yet lead may not be soon soldered to lead nor to brass nor to iron without tin. Neither may these be soldered without grease or tallow.
