General Zoology

This text is general introduction to zoology at the college and university level. The subject matter is arranged to facilitate readings with either lectures or laboratory work and for reference use. Part I deals with general principles of animal biology. After a brief introduction and some history of zoology, the frog is discussed as a typical animal, to establish basic ideas of structure and function. In Part II, following an introduction to the classifying and naming of animals, each chapter describes the structure and physiology of typical animals belonging to each major group -- from the one-celled protozoans to man.
