ACT OF MAN. Every man of sound mind and discretion is bound by his own acts,
and the law does not permit him to do any thing against it; and all acts are
construed most strongly against him who does them. Plowd. 140.
2. A man is not only bound by his own acts, but by those of others who act or are presumed to act by his authority, and is responsible civilly in all such cases; and, in some cases, even when there is but a presumption of authority, he may be made responsible criminally; for example, a bookseller may be indicted for publishing a libel which has been sold in his store, by his regular salesmen, although he may possibly have had no knowledge of it.
