Intelligence and Immigration: By Clifford Kirkpatrick, Ph.D. (Baillière, Tindall and Cox, London, 1926. Pp. 127. Price 18 s.)

A careful examination of the data already collected with regard to the relative intelligence of the members of the different nations and races immigrating to the United States, together with a detailed report of a fresh experimental study conducted by the author upon school children of different races by means of two sets of intelligence tests. As a result of these tests it appeared that Americans and Finns obtained distinctly better scores than did Italians, while French Canadians tended on the whole to occupy an intermediate position. These differences, though still present, were less marked in tests of a non-verbal than of a verbal description (Army Beta and Illinois respectively), showing that part of the differences found in the latter case were due to the influence of language handicap. The author concludes with some general comments and suggestions with regard to 'immigration policy.' The book is distinguished both by precision of experimental technique and by caution and moderation in drawing conclusions on a subject which would easily lend itself to prejudice and bias. It undoubtedly constitutes a useful contribution to an important subject.
