Elementary ChemistryExcerpt from Elementary Chemistry This book is little more than a reproduction of the course in elementary chemistry as now given at Exeter Academy. The course itself has been developed, little by little, during several years of observation and experiment on the part of the writer, to meet the needs of all classes of students, - those who are preparing for a further course of study at college, those who expect to enter a scientific school, and those who go from the academy directly to their life-work. The majority of all these students take chemistry merely as a part of a liberal education, some intend to follow the paths of science; a few will become chemists. In planning this work for beginners the writer has tried to prepare a course that will meet the needs of one class as well as those of another. But in this respect his task has been easy, for the more he has considered the needs of the various classes, the more he has come to believe that the elementary training of all should be alike. The student who is to be a lawyer, a doctor, or a man of business, needs that same careful attention to details, that same power of accurate observation which is expected of the coming chemist; and he who is to be the chemist needs the same high development of his reasoning powers as he who takes chemistry only for the intellectual training it can give.
