THE author addresses himself to the general reader who desires to understand something of the way in which electricity is produced and is utilised in present-day industries. The generation, distribution, and storage of electric power are first explained briefly, and then the author passes on to deal successively with lighting, heating, electric driving of machinery, traction, haulage, etc. Further chapters skim lightly over the leading features of electrochemistry, electrometallurgy, electric welding and cutting, telegraphy and telephony, and medical applications. So large a field can be covered in a little volume like this only by limitation to the barest essentials, but. it is remarkable how complete and accurate is the information given. The reader is, however, hurried on unpleasantly fast, and isnever allowed to pause where his interest is aroused. We are not as a rule over-fond of tabloid education, but the ubiquitous use of electricity in industry and daily life makes itdesirable for everyone to know something of its nature and scope. It will be an advantage to many to have at their disposal so well compiled a summary of the subject rather than to rely on the loose statements too often made in conversation and in the non-technical Press.
