The Advancement of Science, IWO. f Murray. 6s.)—The British Association

has done a very sensible thing in publishing in one compact pamphlet, at a moderate price, the presidential and sectional addresses delivered at its Cardiff meeting. These addresses by some of our leading scientific men deserve to be read at length and cannot fairly be judged by the summaries in the daily newspapers. It was, of course, always possible to obtain separate prints of them, if one were persistent and patient, but it is very much better to have them all in a volume which can be purchased at any bookseller's. Sir Robert Blair's stimu- lating address on educational science, Professor Clapham's comparison between Europe after Waterloo and Europe to-day, and Professor Karl Pearson's remarkable outline of the task of anthropology—" it does matter in regard to the gravest problems before mankind to-day whether our ancestry was hylobatic or troglodyte "—are three papers which deserve very serious attention.
