Book Description
Science. Science is classified truth. Men study the heavenly bodies, note their characteristics, observe their movements, and define their relationships; and having verified their deductions by repeated experiments, arrange the truths they have discovered into systems, and by classifying their knowledge reduce it to a science: this science they call Astronomy. Astronomy is thus the classified arrangement of all known truths concerning the heavenly bodies. Geology, similarly, is the classified arrangement of all known truths concerning the material structure of the Earth. The Kingdoms of Nature. The Natural World has been variously divided for the purposes of study. Linnæus divided it into three kingdoms; (I) the Mineral kingdom (II) the Vegetable kingdom and (III) the Animal kingdom, thus naming the three kingdoms in the order of their natural geneses. The Mineral kingdom comprises the inorganicforms of nature,—those which have no organism and which can only increase by external addition. The Vegetable and Animal kingdoms comprise the organic life of nature,—those forms which are provided with means for promoting their own development and propagating species. The Vegetable kingdom, while easily distinguishable from the Mineral kingdom is in some of its forms so similar to the lower forms of animal life as to suggest relationship between the two; while the Animal kingdom, beginning with the lower forms which approximate so closely to vegetable forms, embraces the whole range of animal life and reaches its highest order in man. The science which treats of organic life as a whole is called Biology, while its two departments are separately known as Botany and Zoology. Natural History is a general term popularly applied to the study of Zoology. Zoology. Zoology is the science of animal life. It deals with the origin of species, and the evolution of the varied forms of animated nature, and treats of the structure, habits, and environment of all living creatures. Scientifically speaking, Zoology is the classified arrangement of all known truths concerning all animal organisms.
