Abstract
WOULD that all books for amateur guidance were written with as full a knowledge of proper principles as this unassuming little work. We are not saying that the machine which the author recommends amateurs to construct is the equal of the commercial dynamos of the current date. His field magnet cores are of cast iron, and not of the best form; his armature might be improved by getting greater cross-section of iron into it. But there is nothing wrongly done. All instructions about the essential details of proper insulation and testing of the work in progress are accurate and full; and an appendix on alternative constructions of field-magnets supplies in some degree the deficiencies of the earlier text.
