Excerpt from An Elementary Book on Electricity and Magnetism and Their Applications: A d104-Book for Manual Training Schools and High Schools, and a Manual for Artisans, Apprentices, and Home Readers The proof of the book was tivice read by Principal G. W. Krall, of the St. Louis (missouri) Manual Training School, and Superintendent F. A. Lowell, of the Rhinelander (wisconsin) Schools and a part of it was read by Assistant Professor Fred A. Fish, of the Ohio State Uni versity. The authors are in their debt for numerous suggestions which have added to the clearness and accuracy of the treatment. Professor A. C. Scott, of the Rhode Island College of Agriculture and Mechanic Arts' (honorary Fellow in Electrical Engineering at the University of Wisconsin), lent efiicient aid while the book was passing through the press, and also made the photographs from which various illustrations vere produced. So much care has been given to the preparation of the manuscript and the reading of the proofs that it may be justly hoped that any remaihing imperfections are of only minor character. The writers will be grateful to teachers and others for notice of inaccuracies or obscure passages which may be discovered.
