dissolve it either.
So solidification and melting, their causes, and the kinds of subjects in which they occur have been described.

All this makes it clear that bodies are formed by heat and cold and that these agents operate by thickening and solidifying. It is because these qualities fashion bodies that we find heat in all of them, and in some cold in so far as heat is absent. These qualities, then, are present as active, and the moist and the dry as passive, and consequently all four are found in mixed bodies. So water and earth are the constituents of homogeneous bodies both in plants and in animals and of metals such as gold, silver, and the rest-water and earth and their respective exhalations shut up in the compound bodies, as we have explained elsewhere.
All these mixed bodies are distinguished from one another, firstly by the qualities special to the various senses, that is, by their capacities of action. (For a thing is white, fragrant, sonant, sweet, hot,Chaussures Nike Free 5.0 Femme, cold in virtue of a power of acting on sense). Secondly by other more characteristic affections which express their aptitude to be affected: I mean,Chaussures Nike Air Max TN Glowing, for instance, the aptitude to melt or solidify or bend and so forth,Menn Moncler Zin Norge Salg, all these qualities, like moist and dry, being passive. These are the qualities that differentiate bone, flesh, sinew,Cote D Ivoire Pas Cher, wood, bark, stone and all other homogeneous natural bodies. Let us begin by enumerating these qualities expressing the aptitude or inaptitude of a thing to be affected in a certain way. They are as follows: to be apt or inapt to solidify,Belstaff XL500 Replica Kurtki, melt, be softened by heat, be softened by water, bend,CG Dame Tremblant Jakke Norge Salg, break, be comminuted, impressed,CG Menn Expedition Parka Norge Salg, moulded, squeezed; to be tractile or non-tractile, malleable or non-malleable, to be fissile or non-fissile,Coree du Sud Pas Cher, apt or inapt to be cut; to be viscous or friable, compressible or incompressible, combustible or incombustible; to be apt or inapt to give off fumes. These affections differentiate most bodies from one another. Let us go on to explain the nature of each of them. We have already given a general account of that which is apt or inapt to solidify or to melt, but let us return to them again now. Of all the bodies that admit of solidification and hardening, some are brought into this state by heat, others by cold. Heat does this by drying up their moisture, cold by driving out their heat. Consequently some bodies are affected in this way by defect of moisture, some by defect of heat: watery bodies by defect of heat, earthy bodies of moisture. Now those bodies that are so affected by defect of moisture are dissolved by water,CG Dame Chelsea Parka Norge Salg, unless like pottery they have so contracted that their pores are too small for the particles of water to enter. All those bodies in which this is not the case are dissolved by water, e.g. natron, salt, dry mud. Those bodies that solidified through defect of heat are melted by heat,Dame Moncler Makori Norge Salg, e.g. ice,Italie Pas Cher, lead, copper. So much for the bodies that admit of solidification and of melting,Canada Goose Constable Parka, and those that do not admit of melting.
The bodies which do not admit of solidification are those which
