Planetary and Stellar Studies. By John Ellard Gore. (Roper and

Drowley.)—Mr. Gore has collected here between thirty and forty papers on various astronomical topics. These, as some of the marvels of the stellar universe, as the binary stars, for instance, and the dimensions of the star-clusters, are specially noteworthy. The twelfth paper, " Variable Stars," may also be mentioned. When we come to the planets, we seem to be more at home ; the figures are not so overpoweringly large. Mr. Gore's is an interesting volume, and not too technical for the ordinary reader.
