Parties interested in patents about to expire, can obtain all nocessary instrnctions how to proceed, free of charge, Dy writing to MUNN & CO. . 37 Park Row, New York. Meclanical Engravings, Such as embellish the Scientific American, are generally superior to those of any similar publication, cither in this country or in l-urope. They are prepfred by our own artists,who have hld long cxperience in this branch of art, and who work exclusively for us. There is one pertinent fact in connection 'Uh the preparation and publication of an illustration ju our columns, that needs to be better understood by many inventors and mannfacturers who pursne a shortsighted policy in bringing their improvcment8 to public notice. They often go to a large expense in printing and circu-ating handbills, which few care either to read or preserve. Now. \l e untlertake to say, that the cost of a first-class engraving. done by our Own artiRt& and printed in one issue of the Scientific American, win amount to less than one-half the sum that would have to be expended on a poorer illl1::tra tion, printed in the same number of circulars,and on i Rheet of paper in Rize equal to one page of our journal. A printed handbill hus no permanent value. Thousands of volumes of the Scientific AmeIUcaU nre bound and preserved for futUre reference-beside, we estimate that every its 0 c of our paper is read by no fewer than one hundred thousand persons. Parties who desire to have their inventions illustrted can address the unflersigncd,who are also prepared to send artists to maIm slmtchcs of manufacturing cstab lishments, with a view to their publication in the Oclen'rific A)'lerTcan For particulars address MUNN & CO., 37 Pal'k How, New York.
