The fibrous formations are not exactly the same and they appear to devdop more rapidly, though adding less to the patient's susceptibility to phthisis. Asbestosis has also been added to silicosis as an occupational disease arising from working in dusty surroundings. _ A.A. Manual of Mining Economics. (Lehrbuch der Bergwirtschaft.) K. Kegel.

Book Review The Art of Pottery. Irma Gall and Vivian Van Etta. Bruce Publishing Co., Milwaukee, Wis. 80 pp. Price 81.35. Eighteen full-page plates and twenty-one illustrations in the text comprising designs, drawings, and photographs. Frontispiece in colors. This book presents a series of fourteen problems in pottery making which the authors have developed and successfully used as a course of elementary instruction for junior high school students. Its chief value to teachers lies in the well-organized "work sheets" by which each prob lem is presented. Necessary materials and tools, steps in the process, and references to helpful literature are set down in a simple but detailed fashion. A professional potter might criticize the text for certain technical inaccuracies and inadequacies, but in spite of its title, the book docs not pretend to be a treatise on the potter's art. As an organized plan for introducing the subject to young students, it will be helpful to many art teachers in the public schools and will, no doubt, find a wide usefulness.
