Excerpt from General Biology, Vol. 1
Several years ago it was our good fortune to follow as graduate students a course of lectures and practical study in General Biology, under the direction of Professor Martin, at Johns Hopkins University. Since that time we have ever been strongly of the opinion that beginners in Biology should be introduced to the subject by some similar method, following in the main the outlines marked out by Huxley and Martin more than ten years ago. The present work thus owes its origin to the influence of the authors of the "Elementary Biology," our deep indebtedness to whom we gratefully acknowledge.
It has not been our ambition to prepare an exhaustive treatise. We have sought only to lead beginners in biology from familiar facts to a better knowledge of how living things are built and how they act, such as may rightly take a place in general education or may afford a basis for further studies in General Biology, Zoology, Botany, Physiology, or Medicine.
It is still an open question whether the beginner should pursue the logical but difficult course of working upwards from the simple to the complex, or adopt the easier and more practical method of working downwards from familiar higher forms. Every teacher of the subject knows how great are the practical difficulties besetting the novice, who, provided for the first time with a compound microscope, is confronted with Yeast, Protococcus, or Am?ba; and on the other hand, how hard it is to sift out what is general and essential from the heterogeneous details of a mammal or a flowering plant. In the hope of lessening the practical difficulties of the logical method we venture to submit a course of preliminary study, which we have used for some time with our own classes, and have found practical and effective.
