fact which it thinks likely to have happened regarding being had to the common course of natural events human conduct and public and private business in their relation to the facts of the particular case. The term that presumption of fact is used to designate an inference of affirmative or dis affirmative of the existence of some fact drawn by Court by a process of probable reasoning from some matter of act either judicially notices, or admitted, or established by legal evidence to the satisfaction of the Court. Without inferring the existence of the fact from others, courts of justice do nothing more than apply, under the sanction of law, a process of reasoning which the mind of any intelligent being, would not in similar circumstance, ever apply for itself; and the force of which rests altogether on experience and observation of the course of nature, the constitution of human mind, the springs of human action and the usage and habits of Society.”
