Abstract
THIS book is for the intermediate and preliminary scientific examinations of the London University, and deals with experiments of a very simple kind. The exercises illustrate the various branches of physics, and they seem to be very suitable for beginners; but we regret that in many cases the descriptions are not accurate. Thus, in describing the measurement of the diameter of a sphere by placing it between two squared blocks, we are told to test the right-angles of the blocks by seeing whether they fit when placed on the table and then turning both blocks over. Surely this is no test. A little further on, in the account of the siphon barometer, the correction for change in density of the mercury and the expansion of the glass scale is attempted, but sadly needs revision and rearrangement. We should also like to know why the corrections for temperature are given with the siphon barometer and not with Fortin's pattern, where they must be equally important. Although many other points in the book require some correction, we think it is written on the right lines, as it aims at simplicity.
