as well as well arranged tables of occupational mortality and morbidity. Part 3 discusses the relations of hospital and medical school work, statistics, government study, and legislation to occupational disease, giving an interesting account of the famous Milan clinic. "The book is a valuable asset to industrial medical literature. The eminence of its collaborators...is an indication of its authoritativeness and its classic character. Its range of subjects and the exhaustive references to the original sources at the end of each chapter make it invaluable as a reference work. While not the first American treatise upon the subject, it is the most comprehensive.” — Dr. T. Grier Miller in Journal of The Franklin Institute, Dec., 1916. 65. Krows, Arthur Edwin.

VDB Although the most of this work of over 500 pages is devoted to the preparation of specifications, the earlier chapters contain some very inspiring advice to young engineers and architects. A strong plea is made for the "square deal" as leading "to the highest type of work, the most economical construction, and the greatest professional satisfaction." Legal and contractual relations are briefly discussed. Notable features are the several excellent bibliographies intended to stimulate further study, as well as sample specifications and many dimensioned drawings. "The portion of the book which deals with these personal problems takes it out of the ordinary run of text books, and marks it as a peculiarly significant addition to any engineer's library." ·Canadian engineer, Nov. 30, 1916; Mining and scientific press, Dec. 30, 1916, p. 964. 67.
