PART II. Structure and General Arrangement op Teeth. Teeth are hard structures usually developed at the commencement of the alimentary canal, in the mouth, and form part of the so-called splachno-skeleton of higher animals. Their use is to seize, divide, or triturate food, in some cases to aid in articulation, to act for defence, and for other purposes in the life of the animal. They are found throughout the animal series. Among the Radiata, the Echini have a beautiful and complex dental apparatus. Gastric Teeth, moved by muscular apparatus, are found in Rotifers, in some of the Gasteropoda, and of the Articulata. Perfect osseous Teeth belong exclusively to fishes, reptiles, and mammals. In some genera in each of these classes they do not exist. In birds, the horny bill performs some of the functions of Teeth, and a horny substance takes their place in the tortoise, and the ornithorhynchus. In some Cetacea, whalebone is substituted for them. f 2$
