Laws of 1858, c. 2090, s. 1.” It was then construed not to excuse a party from testifying to what he knows about the matters in issue. Eaton v. Farmer, 46 N. H. 200.

On this conclusion it is not necessary to consider whether the statute limits the examination of parties in chancery.

Case discharged.
