Abstract
That biology is a unified subject, in contrast to botany and zoology as separate sciences, is continuing to make progress and its advocates are endeavoring to meet the pedagogical needs of teachers of various teaching views, is evidenced by the recent appearance of three new texts within the field. These texts are, Wheat and Fitzpatrick's "Advanced Biology"; Plunkett's "Outlines of Modern Biology"; and Scott's "Science of Biology."
