Although it cannot be actually divided, yet by intendment of law, it may be applied to several purposes; for example, he who lays violent hands upon himself, commits no felony till he is dead, and when he is dead he is not in being so as to be termed a felon; but he is so adjudged in law, eo instante, at the very instant this fact is done.
