A Text-Book of Biology for Students in General, Medical and Technical Courses (Classic Reprint) - Tapa dura

Excerpt from A Text-Book of Biology for Students in General, Medical and Technical Courses

IN this edition the general plan of the previous editions is retained but made more logical by bringing forward the chapters on plants so that the value to be derived from the evolutionary point of view can be employed in the study of the plant types discussed. The chapter on hydra is shifted for a similar reason.

The section dealing with the biology of cells (chapters VIII - XI) has been entirely rearranged and extended in order that it may furnish a better foundation for the present-day conception of biology.

The laboratory suggestions at the beginning of each chapter are omitted and attention is called to Laboratory Outlines by Hargitt and Hargitt which meets the needs of those wishing laboratory directions for the present edition. This book may be secured by writing directly to Professor C. W. Hargitt, Syracuse University, Syracuse, N. Y.

The historical development of biology, typified in large part by the emphasis which certain great men placed first upon one aspect of living things and then upon another, affords a natural approach to our subject: Linnaeus (1707 - 17 78) emphasized the external form of organisms, while Haller (1708 - 1777) inquired into the general physiological activities of living things. These two men may be given credit for defining the two lines of study, morphology and physiology, which enter so largely into all modern courses in biology.
