Excerpt from The Telegraphists' Guide to the New Examinations in Technical Telegraphy: Together With an Appendix Dealing With Dry and Secondary Cells, Univeral Battery System, Direct Reading Battery Instrument, Duplex (Bridge Method), New System of Morning Testing, Fast Speed Repeaters, &C The following pages are a reprint of a series of articles which appeared in the columns of electricity, under the title of Postal Telegraphs. The New Technical Examina tion. Evidence was abundantly furnished of the genuine and widespread appreciation with which the articles were received by readers of that journal, and this circumstance accounts for their re-appearance (with some additions and corrections) in the present form. The papers, it is believed, will meet the whole of the requirements of the new technical examination imposed on telegraphists aspiring to superior appointments in the Government telegraph service. The writer, however, has not by any means confined himself to the bare require ments of that examination, and students preparing for the Examinations in Telegraphy conducted by the City and Guilds of London Institute will, it is hoped, find substantial aid in carefully perusing this little book. The questions, which are typical of those set at the Examinations of that Institute, and of the Science and Art Department, will be found useful by the student in testing his knowledge. Answers have been given to all the arithmetical questions. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
