SCIENCE AND PSYCHOLOGY.

Aspects of Science. By J. W. N. Sullivan. (Cobden-Sand3r3om. 6s. net.)

Throughout the selection of his essays about science, which Mr. Sullivan has given us in this attractive little book, we feel that we are being subtly, delightfully cajoled. The sensation is pleasant, and before the last chapter we are surely devotees of science. With • the aim of stimulating interest in his subject, both in the non-specialist human being and in the other-subject specialist, the author provides chapters to flatter everyone's tastes. Science and the arts, science and the mind, scientific biography, theories, and changing values ; these and other things are lightly touched upon and delicately outlined, always with a suggestion of depths unplumbed and permeated by a consciousness of mystery given back to science. Mr. Sullivan would proselytize well. He knows so wonderfully where to suggest the infinite and where to hold his reader down to fact. Perhaps, some day, he will give us the hidden depths of his knowledge without at the same time losing the common touch" which is so rare and valuable a gift in a scientific essayist whose literary value is far beyond popular taste.
