e.g. pottery, cheese, natron, salt. Some bodies are solidified by both heat and cold. Of this kind are those solidified by refrigeration, that is by the privation both of heat and of the moisture which departs with the heat. For salt and the bodies that are purely of earth solidify by the privation of moisture only, ice by that of heat only, these bodies by that of both. So both the active qualities and both kinds of matter were involved in the process. Of these bodies those from which all the moisture has gone are all of them of earth, like pottery or amber. (For amber, also, and the bodies called ‘tears’ are formed by refrigeration,Dame Moncler Cheverny Norge Salg, like myrrh, frankincense,Ralph Lauren Tee, gum. Amber, too, appears to belong to this class of things: the animals enclosed in it show that it is formed by solidification. The heat is driven out of it by the cold of the river and causes the moisture to evaporate with it, as in the case of honey when it has been heated and is immersed in water.) Some of these bodies cannot be melted or softened; for instance, amber and certain stones,Chaussures Nike Air Max 91 Homme, e.g. the stalactites in caves. (For these stalactites,Chaussures Nike Air Max 2018, too,Maillot Bedoya Pas Cher, are formed in the same way: the agent is not fire, but cold which drives out the heat, which,PJS Herreklær Harraseeket Parkas, as it leaves the body, draws out the moisture with it: in the other class of bodies the agent is external fire.) In those from which the moisture has not wholly gone earth still preponderates, but they admit of softening by heat, e.g. iron and horn.
Now since we must include among ‘meltables’ those bodies which are melted by fire, these contain some water: indeed some of them, like wax, are common to earth and water alike. But those that are melted by water are of earth. Those that are not melted either by fire or water are of earth,Chaussures ZX 700 Unisex, or of earth and water.
Since, then, all bodies are either liquid or solid, and since the things that display the affections we have enumerated belong to these two classes and there is nothing intermediate, it follows that we have given a complete account of the criteria for distinguishing whether a body consists of earth or of water or of more elements than one, and whether fire was the agent in its formation, or cold, or both.
Gold, then, and silver and copper and tin and lead and glass and many nameless stone are of water: for they are all melted by heat. Of water, too, are some wines and urine and vinegar and lye and whey and serum: for they are all congealed by cold. In iron, horn,Stoke City Pas Cher, nails, bones, sinews, wood, hair, leaves, bark,CG Menn Heli-Arctic Parka, earth preponderates. So, too, in amber, myrrh, frankincense, and all the substances called ‘tears’, and stalactites, and fruits,Maillot Ivanovic Pas Cher, such as leguminous plants and corn. For things of this kind are,Menn Moncler Matthew Norge Salg, to a greater or less degree, of earth. For of all these bodies some admit of softening by heat,CG Dame Livigno Parka Norge Salg, the rest give off fumes and are formed by refrigeration. So again in natron, salt, and those kinds of stones that are not formed by refrigeration and cannot be melted. Blood, on the other hand, and semen, are made up of earth and water and air. If the blood contain
