IT is difficult to know how best to review a volume consisting of such varied matter as the Report of the Proceedings of an Educational Congress. Even when restricted to technical education, the subjects that may be legitimately discussed are very numerous; and with the constant widening of the definition, it is not easy to exclude any branch of knowledge, as outside the field of inquiry. After reading very carefully the closely-printed volume of nearly 300 pages, which includes the papers in extenso, and a summary of the discussions, we must own to some feeling of disappointment at the poverty of the results. Several of the writers and speakers are men of knowledge and experience, who write and speak with authority on their respective subjects; but, nevertheless, the volume before us adds little to what was previously known, and we look in vain through its pages for any new light to guide us in solving problems that are still imperfectly understood. The papers are, of course, of unequal merit, and we propose briefly to call attention to a few only, selecting rather those the authors of which show themselves abreast of the difficulties to be overcome.
