Since we penned the article last week about Patents for the Colonies of Britain, we have received a letter from a correspondent, who states that the British Government has no right nor business to grant patents for Colo, nies, which have obtained Legislatorial authority ; " consequently," he says, " all the money that has been received for such purposes, by said Government, was obtained under false pretences." This is strong language. He also asserts that " an American can import a patented article into Canada, in defiance of all the patents there which are. granted only to residents and citizens." We affirm that it is the duty of the British Government to provide a means for foreigners obtaining patents in the colonies, since they cannot obtain such privileges by Colonial authority.
