Abstract

(1) AN unqualified welcome can be given to this excellent translation of the second edition of Prof. Pohl's book, of which the original edition has already received appreciative notice in Nature. Here is given, with a completeness and mastery unapproached in any English work of the kind known to the reviewer, a lucid and systematic account of the physical principles of electricity and magnetism. While the treatment is everywhere didactic, it is shown how the ideas involved and their development are always based on experiment, Prof. Pohl's ingenuity and resource in this direction being most notable. There is very little reference to persons or history, the closely knit argument being almost completely untrammelled by tradition and unhampered by customary modes of presentation; and while the mathematics used is almost negligible, the strict logic and quantitative treatment make the presentation very thorough, and the wealth of illustration and clarity of statement result in a wholly delightful book.
