Excerpt from The Elementary Principles of General Biology
In this book I have endeavored to present in an elementary way some of the fundamental generalizations that are the product of modern research in biology. The artificial division between the study of plants and that of animals is one that is becoming increasingly difficult to maintain, inasmuch as some biological principles are best illustrated by phenomena in the plant world, others by those of the animal world. T have tried, therefore, to utilize both aspects of the subject and to draw my illustrative material impartially from both kingdoms.
The practice that insists upon the student getting his knowledge of natural science at first hand needs nowadays no justification. The laboratory method of study has shown itself to be not only the best means of acquiring a concrete and accurate knowledge of the science studied but also a primary prerequisite for those habits of thought that are essential to what has come to be known as the "scientific method." Nevertheless in Biology the field is so broad and so varied that the student is very likely to lose sight of the fundamental principles that underlie all living nature.
