Stellar Movements and the Structure of the Universe. By A.

S. Eddington. (Macmillan and Co. 6s. net.)—Professor Eddington's learned monograph deals with times and spaces so vast that the mind reels before them—but they are a wholesome change from the war news. The latest theory of our stellar universe is that it is "a bun-shaped system," of which the Milky Way marks the largest circumference. Possibly it looks from outside like one of the wonderful spiral nebulae, which may be similar " island universes." Apparently there are two separate aggregates of stars, one of which is passing through the midst of the other! This essay in immensity is well worth study.
