method of securing patents in all the principal coun
tries of the world. American inventors shonid bear In
mind that, as a general rule, any invention that is vain-
able to the patentee in this country is worth equally as
much in England and some other foreign countri—
Five patents—embracing Canadian. English, German,
French, and Belgian—will secure to an inventor the ex
clusive monopoly to his discovery among about osi
hundred and fiftt .MILLIONS of the most intelligent
people in the world. The facilities of business and
steam communication arc such that patents can be ob
tained abroad by our citizens almost as easily as at
borne. The expense to apply for an English patent Is
$75; German, $100: French, $100; Belgian, $100; Cana
dian, $50.Copies of Patents.—Persons desiring any patent
issned from 1836 to November 26. 1867, can be supplied
