On the Theory and Practice of Art-Enamelling upon Metals. By

H. H. Cunynghame. (A. Constable and Co. 6s.)—Although the history of enamelling is gone into in the introduction, the main part of this work is devoted to technical details. These seem to be very full and practical, and the chemical aspect of the process, and of the manufacture of the colours used, is described.— Another voluble upon the subject by the same author is European Enamels (Methuen and Co., 25s.) In this book the procedure of the previous one is reversed. Here we get a short account of the technical part in the introduction, the main part of the work being devoted to the critical and historical side of the matter.
