Abstract
THIS is a book which, by reason of its thoroughness and its exhaustive treatment of matters which bear upon the main subject, must be recognised as the standard work of reference on phototelegraphy for a long time to come. Such an immense amount of work has been done in this branch of telegraphy that the book must be regarded to a great extent as historical, for even Prof. Korn himself quickly rendered his own selenium apparatus obsolete by the rapid improvements effected in his telautograph.
