Can be patented for a term of years, also new medicines or medical

compounds, and useful mixtures of all kinds.

When the invention consists of a medicine or compound, or a new

article of manufacture, or a new composition, samples of the article

must be furnished, neatly put up. There should also be forwarded a

full statement of its ingredients, proportions, mode of preparation,

uses, and merits.

CANADIANS and all other foreigners can now obtain patents upon the

same terms as citizens.
