Excerpt from Elementary Modern Chemistry The beginner in the study of chemistry finds interest and pleasure, first of all, in the remarkable new facts which are placed before him, and this is both natural and desirable. N 0 one can master the science without much study of proper ties and reactions, and minute acquaintance with as many phenomena as possible is a fundamental requisite. Modern chemistry has, however, a number of general laws which appear. Everywhere through it, connecting various facts in the most interesting way. Before study has gone very far it becomes necessary to begin the statement of these laws and to indicate how the facts already learned group them selves about them. Two purposes are served by this method of presentation. First, a real science of chemistry begins to unfold itself to the student, and second, the acquisition of more new facts is made easier and more interesting. We have planned in this book to present a sufficient number of facts and experiments to fill the time usually devoted to a first course, and at the same time we have endeavored to fit these facts, as far as possible, to the Simpler of the general laws now firmly established as the basis of the science of chemistry.
