PREFACE

In the present Handbook the Ephemeris of the Sun is arranged in, it is hoped, a more useful form. The Editor would be glad to receive any suggestions for making the book more usable for amateurs.

Besides those mentioned in the body of the book, Mr. R. M. Stewart has supplied the phenomena of Jupiter’s satellites and Dr. R. K. Young has furnished the times of the minima of Algol. For the latter Hartwig’s correction of 1h 30m earlier has been applied to Chandler’s formula. The Editor would also give his best thanks to Mr. J. P. Henderson, his assistant in astronomy at the University of Toronto.

The Editor.
Toronto, December, 1916.
