In short, Harvey in his lifetime had the high satisfaction of witnessing his discovery generally received, and inculcated as a canon in most of the medical schools of Europe; he is, therefore, one of the few—his friend Thomas Hobbes says, he was the only one within his knowledge—"Solus quod sciam," who lived to see the new doctrine which he had promulgated victorious over opposition, and established in public opinion. Harvey's views, then, were admitted; the circulation of the blood, through the action of the heart, was received as an established fact, but envy and detraction now began their miserable work.

Let us look as impartially as we may at each of these statements.

They who deny the originality of Harvey's induction, very commonly confound the idea of a Motion of the blood, with the idea of a Continuous Motion in a Circle. It would seem
