*** These elementary works on algebra and trigonometry are written specially for those who will have little opportunity of consulting a Teacher. They are books for "self-help." All but the simplest explanations have, therefore, been avoided, and answers to the Exercises are given. Any person may readily, by careful study, become master of their contents, and thus lay the foundation for a further mathematical course, if desired. It is hoped that to the younger Officers of our Mercantile Marine they will be found decidedly serviceable. The Examples and Exercises are taken from the Examination Papers set for the Cadets of the "Worcester."
