This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

William Francis Channing was born on February 22, 1820 in Boston, Massachusetts, United States, the son of William Ellery Channing and Ruth (Gibbs) Channing.
William attended the Boston schools and then entered Harvard College but he did not complete his course there, as his interest in medicine led him to change to the University of Pennsylvania, from which he received his Doctor of Medicine degree in 1844.
About 1844 Channing settled in Boston and later moved to Providence, but did not practise. His engrossing interest in science caused him to engage in a variety of scientific activities instead. He was an assistant on the first geological survey of New Hampshire, made between 1841 and 1842, and the following year was assistant editor, under Dr. Henry Bowditch, of the Latimer Journal, published in Boston. In 1847, he served as an assistant on the geological survey of the Lake Superior copper region. During the same year he was associated with Dr. John Bacon, Jr. , in the editing and publication of Davis’ Manual of Magnetism (1848).
Channing’s interest in electricity began as early as 1842 when he called attention to the value of applying electric current to the giving of alarms of fire, and the year after his graduation from college he became intermittently associated with Moses G. Farmer, one of America’s pioneer electrical experimenters, in the perfection of a fire-alarm telegraph. Channing and Farmer gradually developed their idea between 1845 and 1851, and in June 1851 the city of Boston voted $10, 000 to test their device. A short time thereafter the system was in operation with Farmer as superintendent. It was crude and unreliable but was basally correct, and the partners, after many trials and tribulations, gradually obtained public favor. It was not, however, until 1857 that they applied for patents. On May 19 of that year they received Patent No. 17, 355, en" titled “magnetic electric fire-alarm telegraph for cities. ” Shortly thereafter the patents were purchased by Gamewell & Company, which organization has since developed the present-day electric fire-alarm system universally in use.
On March 5, 1859, Farmer and Channing obtained a second patent on an improvement in their system which was turned over to the purchasing company. Thereafter Channing applied himself in other directions. In 1865 he patented a ship railway for the inter-oceanic transport of ships, and in 1877 invented a portable electro-magnetic telegraph.
