PATENTS

FOR OVER SIXTY-SIX YEARS the firm of MUNN & CO. has conducted the largest patent practice in the country. We file thousands of applications for patents every year. Our system is so perfected that every case receives the best of attention and is prepared by experts who have had special training in handling every class of invention.

SEND SKETCH. If you will send us a sketch, no matter how crude, we will give you a fair and candid opinion as to whether it is probable a patent can be obtained. All matters of this kind are strictly confidential and the description and sketches will be dated and placed in our secret archives for future reference. This service and our Hand Book on Patents are free.

QUALITY. The quality of our work has given us an unrivaled reputation among Patent Attorneys and we are the recognized American attorneys for many leading Foreign Patent Solicitors. Our staff consists largely of Examiners from the United States Patent Office, who are therefore familiar with the latest procedure and the best practice. Our draftsmen are all expert mechanical constructors who are able to show the invention in operative form.

FREE NOTICE. All patents secured through our house receive a free notice in the SCIENTIFIC AMERICAN. No better or more economical method of introducing your invention to the attention of the public could be devised.

We are prepared to conduct Interference Proceedings, give Validity Opinions, draw up contracts and attend to all branches of legal work connected with Patents, Trade Marks, etc.

SCIENTIFIC AMERICAN

_The Weekly Journal of Practical Information_

THE SCIENTIFIC AMERICAN, founded over sixty-seven years ago (1845), has become to-day the official organ of those people who really do things, and want to know what others are doing; it is for the one whose whole business success depends upon these great mechanical, chemical, electrical and engineering achievements, which are rapidly and surely making this nation.

THE SCIENTIFIC AMERICAN is the authority; it is always up to date; and gives its readers the first news as well as the most complete news of any new development in the Sciences, Arts, Manufactures, etc. Some of the department features are:

HANDY MAN'S WORKSHOP.--In this department those who use tools either for pastime or profit will find suggestions which will be helpful.

HANDY MAN'S LABORATORY.--This is a department of Experimental Science with many useful and interesting experiments along the lines of modern scientific thought.

NOTES AND QUERIES DEPARTMENT.--In which is published replies to our correspondents, embracing the widest range of topics. An able corps of experts is engaged to attend to this correspondence and the service is free to our subscribers.

INVENTORS' DEPARTMENT.--In these columns inventors have their say; their trials and tribulations and final successes are fully discussed. Inventors are also given an opportunity to present their mechanical ideas to the world. There is also a column of "Patent Office Notes" and a column of "Legal Notes" in which questions of Patent Law, about which inventors and manufacturers should be informed, are briefly and simply elucidated.

CURIOSITIES OF SCIENCE AND INVENTION is a department of notes in which all the curious and ingenious ideas of the day are illustrated and briefly described.

The "Scientific American" is published weekly and a year's numbers contain over 1200 fine illustrations and about twice as much text as a standard magazine. Subscription price, $3.00 per year; $1.50 for six months. Sample copy free.

The Scientific American Cyclopedia of Formulas

Edited by

ALBERT A. HOPKINS

OCTAVO. 1077 PAGES. 15,000 RECEIPTS Cloth, $5.00. Half Morocco, $6.50. Postpaid

This valuable work, which is partly based on the twenty-eighth edition of "The Scientific American Cyclopedia of Receipts, Notes and Queries," contains a collection of about 15,000 selected formulas, covering nearly every branch of the useful arts and industries. Never before has such a large collection of valuable formulas, useful to everyone, been offered to the public.

This work may be regarded as the product of the studies and practical experience of the ablest chemists and workers in all parts of the world, the information given being of the highest value, condensed in concise form, convenient for ready use. Almost every inquiry that can be thought of relating to formulas used in the various manufacturing industries will here be found answered.

The formulas are classified and arranged into chapters containing related subjects, while a complete index, made by professional librarians, renders it easy to find any formula desired.

Those engaged in any branch of industry will probably find in this volume much that is of practical use in their respective callings. Those in search of salable articles which can be manufactured on a small scale, will find hundreds of most excellent suggestions. It should have a place in every laboratory, factory and home.

An eight-page descriptive circular and complete table of contents will be furnished on application.

Experimental Science

Elementary Practical and Experimental Physics

By GEORGE M. HOPKINS
