Fifteenth Year of Publication.

PREFACE

The Handbook for 1923 follows the same lines as that for 1922. The general sketch of the planets, it is hoped, will be found useful in giving a view for the entire year, while the detailed account for each month gives the observer the times for the phenomena each day.

Descriptions of the constellations and the star maps are not included, since fuller information is available in a better form and at a reasonable price in many publications, such as: Young’s Uranography (72c.), Upton’s Star Atlas ($3.00) and McKready’s Beginners’ Star Book (about $4.00).

The Handbook is somewhat delayed this year through the Editor’s absence on the eclipse expedition to Australia. Especial thanks are due to Mr. J. A. Pearce, M.A., now at the Lick Observatory; Mr. R. M. Motherwell, M.A., and Dr. R. J. McDiarmid, Dominion Observatory, Ottawa; and to Messrs. J. H. Horning, M.A., H. F. Balmer, B.A., and J. P. Dandy, Toronto.

The Editor.
Toronto, December, 1922.
