Books with title Elements of Zoology

Excerpt from Elements of ZoologyWe know that a bird eats, moves, and breathes, and that its blood circulates; but plants also eat, respire through their leaves, have a circulation of sap, and some are endowed with locomotive powers. When we descend to the lower forms of animal and vegetable life, the points of similarity become almost identical; the swift-mov ing diatom so resembling some of the lowest animal forms that it is well-nigh impossible to distinguish be tween them. The plants, however, have no nervous sys tem, no special organs Of circulation or digestion that characterize the majority of animal forms, so that an ani mal differs mainly from a plant in possessing, as a rule, a nervous system and special organs of Circulation and digestion.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

It seems to the author that three kinds of work should be included in the elementary study of zoology. These three kinds are: (a) observations in the field covering the habits and behavior of animals and their relations to their physical surroundings, to plants, and to each other; (b) work in the laboratory, consisting of the study of animal structure by dissection and the observation of live specimens in cages and aquaria; and (c) work in the recitation- or lecture-room, where the significance and general application of the observed facts are considered and some of the elementary facts relating to the classification and distribution of animals are learned....

Excerpt from Elements of GeologyThe meaning and scope of geology. - Geology has to do with the history of the earth and of its inhabitants. Its field is so broad that for the sake Of convenience and specialized study it has been divided into numerous branches. Geology is concerned with the different members of the solar system and with other heavenly bodies in so far as they yield evidence as to the origin of the earth, or affect the activities now in progress upon it. This division of the general subject is some times called Astronom'ic Geology, and is related closely to the science of Astronomy. The processes and agents at work changing the earth must be studied carefully by the geologist, for they are shaping the present chapter in the history of the earth, and an understanding of them affords also a key by which much of its earlier history, recorded in the rocks, may be read. This phase of the subject is Dynamic Geology, and it has common ground with the special science of Physi ography or Physical Geography, with Meteorology, the science of the atmosphere, and with other sciences. The study of the remains and impressions 'of the plants and animals of past ages that are found in the' rocks is Paleontology; it is really the historical side of Botany and Zoology. Structural Geol ogy is concerned with the arrangement of the materials of the earth. That branch of geology which deals with minerals is Mineralogy, that which studies rocks is Petrology; both are connected closely with Chemistry. There are still other divisions of geology, but the ones mentioned are chief, and.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
