✦ Synopsis

Marius used a telescope and did observe the inner satellites of Jupiter, though apparently he did not realize their true nature, for which discovery the Italian must be credited. It is hardly true, as we read on page 128, that the rings of Saturn can ever be seen "with prism binoculars," unless they are much more powerful than those owned by most of us.

Though the illustrations have been fairly well selected, many of them are very • poorly reproduced. This is particularly true of Figs. 5 ° and 54, made from G. W. Ritchey's magnificent photographs of the Pleiades, the Orion nebula and the Andromeda nebula. The two star maps, Figs. 41 and 42, showing the northern sky on a winter evening and the southern sky in summer, are poor. Many of the constellations are distorted beyond recognition, and it is hard to see how the Great Dipper managed to get into the southern sky[ The book is nicely bound, printed on good paper and provided with an index. Perhaps if a future edition is required, the errors may be corrected.
