PATENTS.


In connection with the SCIENTIFIC AMERICAN, Messrs. MUNN & Co. are
Solicitors of American and Foreign Patents, have had 38 years'
experience, and now have the largest establishment in the world. Patents
are obtained on the best terms.

A special notice is made in the SCIENTIFIC AMERICAN of all Inventions
patented through this Agency, with the name and residence of the
Patentee. By the immense circulation thus given, public attention is
directed to the merits of the new patent, and sales or introduction
often easily effected.

Any person who has made a new discovery or invention can ascertain, free
of charge, whether a patent can probably be obtained, by writing to MUNN
& Co.

We also send free our Hand Book about the Patent Laws, Patents, Caveats.
Trade Marks, their costs, and how procured, with hints for procuring
advances on inventions. Address
