Advice in Regard to Patents
The influence of invention on modern life can be very justly estimated by a perusal of “The Progress of Invention in the Nineteenth Century.” It is, of course, well known that inventors are necessarily assisted in the prosecution of their applications for patents in the Patent Office by patent attorneys. It gives Messrs, Munn & Co. pleasure to announce that they have prosecuted, during a period of over fifty years, some of the most important patent cases which have ever been sent to the Patent Office. During this long period they have filed and prosecuted over one hundred thousand applications for patents. Their reputation is such that inventors have found that they may submit their ideas with entire confidence that their trust will not be betrayed, and that their interests will be protected to the fullest extent. They secure patents, trade-marks, caveats and copyrights. A little book entitled “Hand-Book on Patent Practice” will be sent free to any address, and any questions relating to patents will be cheerfully answered by return mail without charge. Thousands of clients all over the United States, many of them the most successful inventors which this country has produced, have had the professional services of Messrs. Munn & Co. in the preparation and prosecution of their patent applications before the United States and foreign patent offices. The integrity of this firm, and their attention to this branch of their business, has resulted in the largest practice of any firm of patent attorneys in the United States. Inventors are invited to write freely regarding their inventions, and their sketches will be carefully and promptly examined. All communications of this kind are treated as strictly confidential. The readers of “The Progress of Invention in the Nineteenth Century” may also be interested to know that Munn & Co. have offices in both New York and Washington, and thus are able to keep in close touch with the work of the Patent Office. They have unsurpassed facilities for examining and reporting on the probable patent-ability of inventions, and they render opinions on questions of infringement and validity of patents; and they also have been most successful in the prosecution of interferences.

Scientific American Supplement
Established 1876
This journal is a separate publication from The Scientific American, and is designed to extend and amplify the work carried on by the parent paper. In size and general make-up it is uniform therewith, covering sixteen pages of closely printed matter, handsomely illustrated. It has no advertising pages, and the entire space is given up to the scientific, mechanical and engineering news of the day. It differs from The Scientific American in that it contains many articles that are too long to be published in the older journal or of a more technical nature. College professors and students find this edition especially adapted to their wants. It contains reports of the meetings of the scientific societies, both in this country and abroad, and abstracts of many papers read before such societies. It has a page of short notes concerning the electrical, engineering and general scientific news of the day, together with a column of selected formulæ. Each number contains much foreign scientific news, and, when taken in connection with The Scientific American, it places before the reader a weekly review of the latest and most important discoveries and the most advanced technical and scientific work of the times all over the world.
PRICE FOR THE SUPPLEMENT, $5 A YEAR, or one copy of The Scientific American and one copy of Supplement, both mailed to one address, for one year, for $7. Address and remit by postal order or check.

The SCIENTIFIC AMERICAN,
ARCHITECTS’ and BUILDERS’ EDITION.
$2.50 a Year
Single copies, 25 cts.
This is a special edition of the Scientific American, issued monthly—on the first day of the month. Each number contains about forty large quarto pages, equal to about 200 ordinary book pages, forming, practically, a large and splendid Magazine of Architecture, richly adorned with elegant plates in colors and with fine engravings, illustrating the most interesting examples of modern architectural construction and allied subjects. A special feature is the presentation in each number of a variety of the latest and best plans for private residences, city and country, including those of very moderate cost, as well as the more expensive. Drawings in perspective and in color are given, together with plans, specifications, costs, etc. No other building paper contains so many plans and specifications, regularly presented, as the Scientific American. Thousands of dwellings have already been erected on the various plans we have issued, and many others are in process of construction.
Architects, builders and house owners will find this work valuable in furnishing fresh and useful suggestions. All who contemplate building or improving homes, or erecting structures of any kind, have before them in this work an almost endless series of the latest and best examples from which to make selections, thus saving time and money.
Many other subjects, including sewerage, piping, lighting, warming, ventilating, decorating, laying out of grounds, etc., are illustrated. An extensive Compendium of manufacturers’ announcements is also given, in which the most reliable and approved building materials, goods, machines, tools and appliances are described and illustrated, with addresses of the makers, etc.
The fulness, richness, cheapness and convenience of this work have won for it the largest circulation of any architectural publication in the world.
