Following the example of 1934 and 1935, there is no list of stars occulted by the moon in the present issue of the Handbook. The computations for Toronto and Ottawa, published in 1931, 1932, demanded much labour which seemed hardly warranted by the results attained. Our country extends over so many degrees of longitude that predictions for a single place are of limited use. The Editor would be glad to publish brief lists for well distributed stations and asks for suggestions.

No star maps are included in the Handbook, but the following are recommended: Four circular maps, 9 inches in diameter, roughly for th e four seasons, obtainable from th e Director of University Extension, University of Toronto, for one cent each. A set of 12 circular maps, 5 inches in diameter with brief explanation, is supplied by Popular Astronomy, Northfield, Minn., for 15 cents. Young's Uranography, contains four maps with good descriptions of the constellations, suitable for small telescopes (Ginn and Co., 72 cents). Norton's Star Atlas and Telescopic Handbook is larger and excellent. (Gall and Inglis, price 12s. 6d.; supplied also by Eastern Science Supply Co., Boston).

In the preparation of this Handbook assistance has been received from Mr. Gordon Shaw and Mr. Robert Peters of the Victoria Centre, as well as Dr. W. E. Harper and Dr. J. A. Pearce of the Dom. Astroph. Obs’y; Miss M. S. Burland and Dr. R. J. McDiarmid of th e Dom. Obs'y, Ottawa; and Miss Ruth Northcott, Dr. F. S. Hogg and Dr. P. M. Millman of the David Dunlap Observatory.
