Admissions are relevant and may be proved as against the person who makes them, or his representative-in-interest; but they cannot be proved by or on behalf of the person who makes them or by his representative-in-interest, except in the following cases:
(1)
An admission may be proved by or on behalf of the person making it, when it is of such a nature that, if the person making it were dead, it would be relevant as between third persons under section 32.
(2)
An admission may be proved by or on behalf of the person making it, when it consists of a statement of the existence of any state of mind or body, relevant or in issue, made at or about the time when such state of mind or body existed, and is accompanied by conduct rendering its falsehood improbable.
(3)
An admission may be proved by or on behalf of the person making it, if it is relevant otherwise than as an admission.
