PREFACE TO THE THIRTEENTH EDITION

THIS handbook, which in the present edition has been completely revised, is not written with the object of enabling every man to be his own Patent Agent, for it is simply impossible for any ordinary individual to become a good Patent Agent without years of training in a large Patent Office, and without having special adaptability to the work.

That the book may be worthy of the kind favour which the previous editions so amply received, and be a genuine assistance to inventors, manufacturers, and patent investors generally, is the earnest wish of the Author.

LIVERPOOL, December, 1904.
