Issue No. 15, Toronto, 1960-61

An INTRODUCTION to the wonders of astronomy, published by the ROYAL ASTRONOMICAL SOCIETY OF CANADA (TORONTO CENTRE) and distributed free to visitors at the Society's open-air meetings and Exhibition display; also at the Saturday public evenings at the David Dunlap Observatory.
