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.
