Illustrated 12mo $2.60
Intended to serve as an introduction to the science of Geology, both for students who desire to pursue the subject exhaustively and also for those who wish merely to obtain an outline of the methods and principal results of the science. To the future specialist such a preliminary survey of the whole field will afford the necessary orientation. To the non-specialist the graphic presentation of the outlines of the subject cannot fail to prove both interesting and informing. The book aims to cultivate a proper scientific attitude by training the student to carefully distinguish between fact and inference and between observation and hypothesis. He is taught to weigh his evidences carefully, and while balancing probabilities suspend judgment where the data for decision are insufficient.
The new edition incorporates the results of all the important advances made in geological knowledge in recent years. The number of illustrations has been greatly increased, thus adding to the admirable clearness of the text.
Guide to the Study of Animal Ecology

This work is the outgrowth of the author’s efforts during the last ten years to find some consistent and satisfactory working plan for handling the almost bewildering number of facts of ecological significance which have been accumulating in the literature of zoölogy, biology, and the allied sciences. An ecological point of view is described more fully than other subjects, so that the student may see the need of familiarity with those tests or criteria by means of which he may be able to determine for himself ecological relations and the validity of ecological studies. The other phases are treated less fully in the discussions and with more detail bibliographically, so that this may be a useful source-book. In fact, the very extensive and up-to-date bibliography is one of the important features of the entire book.
