The principal objects of the series are to supply the lack—in some subjects very great—of authoritative books whose principles are, so far as practicable, illustrated by familiar American facts, and also to supply the other lack that the advance of Science perennially creates, of text-books which at least do not contradict the latest generalizations. The books of this series systematically outline the field of Science, as the term is usually employed with reference to general education. The scheme includes an Advanced Course, a Briefer Course, and an Elementary Course.

In ordering be careful to state which course is desired—Advanced, Briefer, or Elementary.
