Head Matter:
Jackson v. Van Alen, 8 J. R. 495.
In S. Ct. 5 J. R. 440.
Evidence as to Construction of Patent.
The-Court of Errors in this case reversed the decision of the Supreme Court, upon the question of the admissibility of certain evidence as to the sense of the parties in regard to the legal effect of a patent of lands, which that court held inadmissible.

Opinion:
The Court of Errors held, that although the construction of a grant is matter of law, yet its legal effect, (deducible from the terms used in it, or from matter subsequent which, as showing the sense of the parties, may authorize a larger or narrower construction so as to include or exclude particular premises,) is a matter of fact for a jury only to decide.
