PER CURIAM.
This is an appeal from a judgment in the District Court on a jury verdict entered in a personal injury case.
Appellant [plaintiff] complains of the admission, on cross-examination, of certain evidence, of the admission into evidence of a certain traffic regulation and the refusal to admit in evidence another regulation, and of certain rulings in connection with the court's charge.
Our examination of the record convinces us that, under the circumstances of this case, there exists no error affecting substantial rights.
Affirmed.
