Book Description
Excerpt from Patents for Inventions: Abridgments of Specifications Relating to the Preparation of India-Rubber and Gutta Percha; A. D. 1791-1866 The Indexes to Patents are now so numerous and costly as to render their purchase inconvenient to a large number of inventors and others, to whom they have become indispensable. To obviate this difficulty, short abstracts or abridgments of the Specifications of Patents under each head of Invention have been prepared for publication separately, and so arranged as to form at once a Chronological, Alphabetical, Subject matter, and Reference Index to the class to which they mlate. As these publications do not supersede the necessity for consulting the Specifications, the prices at which the printed copies of the latter are sold have been added.
