EASY EXPERIMENTS IN SCIENCE. By Herbert McKay, B.Sc. (Oxford University
Press. 2s. 6c1.)
Not since the publication of the late Mr. F. W. Sanderson's Hydrostatics have we chanced upon so beguiling an elementary science book as that before us, a little work calculated to turn even the youngest occupant of the schoolroom into a small " natural philosopher." All the many experiinents described discover or prove some natural law in the simplest possible way and usually with no more apparatus than can be decently borrowed from the kitchen or pantry. No doubt breakages will result and incredible messes will be made, but such occurrences are in any case common in every properly con- ducted house containing children. It should be some comfort that tumblers are being smashed and carpets are becoming waterlogged in the sacred cause of science rather than from mere aimless, or rather misdirected and inconsequent, " playing with things." It should be added that the line illustrations of Mr. McKay's book are so cleanly and forcibly drawn as in themselves to afford to the young an admirable example of the value of clear and direct graphic expression and how it may be achieved.
