Excerpt from The Principles of Biology
In an introductory course in biology a text-book is helpful because the notes taken by lower class students are usually unsatisfactory, if not useless and require much time. This volume contains an outline of a course given by the author for more than ten years. It is designed to supplement the practical work in the laboratory and field, and to relieve the student of the greater part of the burden of taking lecture notes. Purely discriptive matter is reduced to a minimum and examples are largely omitted because the teacher is supposed to have sufficient command of the subject to supply these, and local and familiar examples are always better for illustration than those less well known. The figures in the book are regarded as an important part in the presentation of the subject and should be carefully studied. Many points omitted or only briefly alluded to in the text are explained by them.
Part I is designed to acquaint the student with the fundamentals of plant organization and life processes. Part II does the same for animals but in a different and more thorough method. Part III discusses the most important general biological phenomena. The difference in treatment of plants and animals rests on well-known pedagogical principles which need not be discussed here. There is little in the book for which originality can be claimed, but justification for publishing rests on the fact that there is at present no text which even approximately covers the field in subject-matter and method of treatment.
