An Elementary Course of Practical Physics. By A. M. Worthington,
M.A., F.R.A.S.—The great attention now given to science on the modern side of all good schools is a sufficient reason for Mr. Worth- ington's excellent brochure. All scientific teachers lay great stress upon the value of practical work in the laboratory. But laboratories and their appliances are costly, and it is not every school which can afford to supply this deficiency, nor every parent that is willing to pay an adequate share of the expenses. Most parents, not scientific themselves, have an idea that a great deal of first-class science can be got out of shilling primers, and are inclined to reproach the science- master if the local production of Faradays and Tyndalls runs short. Mr. Worthington gives a list of the requirements of a laboratory for elementary work, and a most judiciously-chosen course of practical physics, also elementary. He deserves all praise for his brevity, thoroughness, and exactitude.
