PREFACE.

THIS work is intended primarily for use as a school text-book. We hope it will meet the wants of all who are beginning Trigonometry, and be found adequate for the majority of Army Candidates.

Our index of contents will show that we have departed somewhat from the recognised treatment of the subject, but we believe that our arrangement will prove suitable for most beginners, and minimise their difficulties. Those who disapprove of it will find no difficulty in directing the chapters to be read in an order more in accordance with their own views or the capacities of individual pupils.
