“ All objects, including the two classes just mentioned, are, as a rule, at a lower temperature, or colder, than our bodies; hence, when we touch an object, as wood, which will not conduct heat readily, no heat flows from the hand into the object, and it does not give us the impression of being cold; but when the warm hand comes in contact with an object which is a good conductor of heat, such as metal, heat flows from the hand into the object, tending to warm it to the same temperature as the body. ”

“ Practically all common objects, except metals, with which we come in contact are non-conductors of heat, that is, heat will not flow through them readily. Such objects are wood, paper, cloth, etc.; but metal objects, generally speaking, conduct heat readily. ”

“ It is interesting to notice that the hand, which is exceedingly sensitive to differences of touch, is not as sensitive to heat and cold as the face, so that when you try the cold feeling of metals, it is best to apply them to your cheek or nose. ”
