Practical Chemistry. By M. M. Pattison-Mair and D. Carnegie. (Cambridge

University Press.)—A. companion volume to the "Ele- mentary Chemistry." This is a graduated course of practical chemistry, furnished also with numerous experiments and several woodcuts on dissociation, atomic weights, relative affinity, and the constitution of compounds. A teacher would find it necessary to vary considerably some of the experiments, as well as qualify some of the deductions. Some numerical and analysis tables complete the book.
