About this book
The American Electro Magnetic Telegraph presents reports of Congress and descriptions of telegraphs employing electricity or galvanism, with wood engravings accompanying the account. The account of the electro magnet calls the component the basis of the invention in its present construction and says the invention would fail without it. The description of magnet construction explains an arrangement intended to make putting on the coils or taking them off easy.
The discussion of post office power argues that the government's resulting weight and influence ought to be considered as bringing a correspondingly heavy obligation to make that power useful to the people to its utmost capacity. The illustrations of Mr. Bain’s telegraph represent matching instruments at Portsmouth and London.
