Fox

[AS.] A carnivorous wild animal belonging to the Dog tribe, famous for its cunning. It has a fine coat of reddish-brown fur, low forehead, ears pointed, and wide at the base, and a splen¬ farm, which it visits by night. Its food is poul¬ insects. It is fond of berries and fruits, grapes ; unit of French coinage since 1795. It is divided into one hundred centimes. from the solid to the liquid, or from the liquid to the gaseous state, heat is required to effect the change; and when heat is not supplied from without to produce the change, the body itself, and everything in contact with it, becomes colder. This is the principle of freezing mixtures. When ice and salt are mixed, the salt (from its tendency to absorb and di olve in water) will cause the ice to melt. But ice in melting uses up a large quantity of heat, and the result is (since the heat has in this case been withdrawn from the sub¬ stances themselves) that the mixture is rendered very cold, and water poured into a test-tube and placed in it will freeze. In practice, freezing mixtures are used for producing artificial ice in moderate quantities, and in freezing creams, etc. at which a fluid begins to freeze. Applied to water, the freezing-point is 320 F. and zero or o° C. Mercury freezes at 39°F. below zero. by a fine saw.

It has a smooth, slimy skin of a greenish-brown or reddish color it has teeth on the upper jaw, and by this is distinguished from the toad, which has no teeth. Its tongue is soft and fleshy, and fixed on the front of the mouth, but free behind, so that it can roll out and catch an insect. The tip of the tongue is always covered with a treacly, glutinous matter, to which any insect caught adheres. The frog flings its food down its throat with a very rapid motion. As with the rabbit, its fore limbs are port the swimming web. It has four fingers in
