Description; pointing out. That which is said or written to designate a thing or person.
In evidence. Absolutely convincing proof. That proof which excludes all possibility of error. Whatever is said or written to designate a thing or person. For example, a gift of so much money, with a fund particularly referred to for its payment, so that if the fund be not the testator’s property at his death, the legacy will fail; this is called a demonstrative legacy. 2. A legacy given to James, who married my cousin, is demonstrative; these expressions present the idea of a demonstration; there are many James, but only one who married my cousin. 3. By demonstration is also understood that proof which excludes all possibility of error; for example, mathematical deductions.
