Such odontomes may be considered as arisingfrom an abnormal growth of all the elements of a tooth-germ—enamel-organ, papilla, and Fig. 127.—Left lower jaw of a young marmot with a large radicularodontome connected with the incisor. (Nat. size.) Not only is this species of odontoma composite in that thetumours comprised in it originate from all the elements of atooth-germ, but they are composite in another sense : manyof these tumours consist of two or more tooth-germs in-discriminately fused. But they differ from the cementomascontaining two or more teeth in the fact that the variousparts of the teeth composing the mass are indistinguish-
