So the teeth here must have sharp 8 ANIMAL LIFE IN FIELD AND GARDEN edges that come together and operate like the bladesof a pair of scissors. I think I have said enough on that subject. Now,which of you will tell me what kind of food goeswith each of the teeth I show you here? And Uncle Paul laid before his hearers the twoteeth pictured on these pages, with others to follow. —c. Tooth of a HorseA, the tooth entire; B, cross-section of an unworn tooth; G, cross-section of a worn tooth ; e, enamel; c, cement; i, ivory; p, dental pulp. The first tooth, said Emile, is flattened andvery wide at the top; it must crush and grind byrubbing against a tooth of the same kind in the op-posite jaw. So it is the tooth of an animal that eatsfodder. It is indeed, Uncle Paul replied, the tooth ofan herbivorous animal, a horse. The second, continued Emile, is composed ofseveral broad points with edges almost as sharp asknife blades. It must be meant for cutting flesh. TEETHanimallifeinfiel00fabr
