    INVESTIGATIONS ON CONDUCTION OF HEAT. Why does not cold wood produce an action equal to that of the cold metal ? Simply because the heat communicated to it is accumulated at its under sur- face; it cannot escape through the bad conducting wood as it escapes through the metal, and thus the quantity of heat withdrawn by the wood is less than that withdrawn by the copper. A similar effect is produced upon the human nerves. When you come into a cold room and lay your hand upon the fire- irons, the chimney-piece, the chairs and the carpet, in succession, they appear to be of different tempera- tures; the iron chills you more than the marble, the marble more than the wood, and so on. It is needless to say that the reverse takes place when we enter a hot room, that is to say, a room hotter than your own body. You would certainly suffer if you lay down upon a plate of metal in a Turkish bath; but you do not suffer when you lie down on a bench of wood. By preserving the body from contact with good conductors, very high temperature may be en* dured; eggs may be boiled and beefsteaks may be cooked by the heat of an apartment in which the bod- ies of living men sustain no injury. Blagden and Chantrey exposed themselves in ovens to tempera-
