received much attention while so much time had to be spent upon the tables of weights and measures in ordinary use. When these cease to be legal, not only will the teaching of Arithmetic be rendered more rational, but a large amount of time will be set free which can be applied to the promotion of science teaching.

Looking back over the years that have elapsed since the passing of the first Elementary Education Act, it is evident that the constant tendency has been to add to the curriculum of the schools; and some of the most recently recommended additions to the time-table include manual instruction and physical exercises. The difficulty of finding time for these has led to the suggestion that the generally recognised hours of schooling might be extended in the case of the elder scholars. This course would involve some practical inconveniences; and in view of the fact that the children pass their Standards now at an earlier and more immature age than they did some years ago, it is a question worth consideration whether the time has not arrived when the recognised school age should be raised from thirteen to fourteen, and the work of the Standards made to spread over this extended period. Such an arrangement would have the manifest advantage of affording a broader and more practical education, without over-pressure to either the teachers or the taught.

Quantitative Analysis by means of Electrolysis.-Second Report of the Committee, consisting of Professor J. EMERSON REYNOLDS (Chairman), Dr. C. A. KOHN (Secretary), Professor P. FRANKLAND, Professor F. CLOWES, Dr. HUGH MARSHALL, Mr. A. E. FLETCHER, Mr. D. H. NAGEL, Mr. T. TURNER, and Mr. J. B. COLEMAN.

A PRELIMINARY report was furnished by the Committee last year in which the contemplated plan of work was outlined.

The bibliography of the subject has been completed and is appended.

The experimental work has been carefully organised, and the results on the determination of bismuth and of tin are nearly complete. Other work is in progress, but the Committee prefer to hold over these results until next year in order that they may be added to and may include methods of separation of some of the metals.

Considerable attention has been given to the choice and arrangement of the special apparatus required. A detailed description of the arrangements adopted will be given in the next report.

As the bibliography is completed, the Committee propose to devote their attention during the coming year exclusively to experimental inquiries.
