The Manufacture of Paper. By R. W. Sindall. (A. Constable

and Co. 6s, net.)—Mr. Sindall tolls us what paper is made of—a subject much larger now than it was fifty years ago, and still increasing—and bow it is made. What the skill of the engineer does, and what the knowledge of the chemist supplies, are hero sot forth. Analyses of the substances chiefly used, esparto grass, for instance, and wood-pulp, are given. Various qualities and uses of the article are distinguished ; we read about "brown paper,"--how different from the article of fifty years ago, which would neither tear nor burn In fact, the whole subject is treated by an expert.
