SCIENCE PROGRESS. Edited by Sir Ronald Ross. (Murray. 6s. net.)

This valuable quarterly is becoming more and more in- dispensable, both to scientific workers and to laymen who are anxious to keep in touch with the rapid development of the natural sciences. Among the technical articles and summaries we notice an interesting comment by Mr. F. W. Shurlock, of the Derby Technical College, on the three scientific pictures by Joseph Wright, of Derby (1734-97), which are now exhibited together in the art gallery of his native town. From the artistic standpoint Wright was concerned, like Gerard Doss, to paint figures in strong candle or lamp light. But he contrived at the same time to represent, with a fidelity equal to that of his Dutch master, the details of the early scientific experiments that were being made by some learned fellow- citizen of Derby. Mr. Shurlock deals with " The Orrery," " The Air-pump," and " The Aichymist" ' • the second picture is, we think, on loan from the National Gallery.
