The plaintiff’s motion to add interest to the verdict should not have been granted. If he desired an instruction for the allowance of interest, he should have asked for it before the jury retired. By his failure to do so, he waived his right to it and all objections for the want of it, in the same manner he would his right to any other instruction. Pitman v. Mauran, 69 N. H. 230.

Exception sustained.
