Porcelain. By William Burton, F.C.S. (Cassell and Co. 7e. 6d.

net.)—Mr. Burton's book covers a wide field. The author, who is a practical man, and distinguished by having produced some fine glazes, tells us first what the material of porcelain is. This varies considerably, though in all kinds it consists chiefly of silica and alumina. These are always more than nine-tenths of the whole (" Bristol" contains-as much as 96'08 of the two), but the proportions vary from 560 silica and 84'5 alumina in "Sevres" to 75-29 and 19'0 in Japanese.- We then are introduced to the various manufactures, the Chinese, the Japanese, and the European being taken in succession, the English naturally occupying nearly half of the space. This will be found a useful handbook for any one who desires to get a general acquaintance with the subject.
