Yet it is useful and convenient to think of living species in these two main divisions—plants and animals. Most of the names used in classifying plants and animals are Latin or Latin in form. In these outlines all Latin names have been anglicized to facilitate their pronunciation except where the Latin form is as easy or as familiar. The outlines are, of course, not complete. The subdivisions have been carried only as far as students are likely to need them. Groups which are of little interest to any except the professional taxonomist have been either treated by a special note or omitted entirely. The successive subdivisions in the plant-and-animal classification scheme are shown on pages 40 and 41; the "relatedness" of the various branches is shown in the frontispiece. 687.
