PATENTS.

In connection with the SCIENTIFIC AMERICAN, Messrs. MUNN & Co. are

Solicitors of American and Foreign Patents, have had 40 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
