This is an action of tort to recover compensation for personal injuries received by the plaintiff by reason of a collision on a public way, between a motorcycle ridden by him and an automobile driven by the defendant. The bill of exceptions states: "In charging the jury the court said, among other things, as follows: ‘The first proposition in this case is, has the plaintiff satisfied you by a fair preponderance of the evidence, that term, which means the greater weight of the evidence, that his injuries are the result solely of the defendant’s negligence committed then and there at the time of the collision by his acts just before and at the time of the collision?’ The court in another place said: ‘The first proposition for you to decide is, was Mr. Burnett negligent, and if so, of what does the negligence consist? What did he do he ought not to do? What did he leave undone he ought to have done? Assuming that you find that point in favor of the plaintiff, that Burnett was negligent, and that negligence was the sole cause of the injuries, that is not enough to entitle the plaintiff to a verdict. Now, then, by his answer the defendant asserts that the plaintiff himself was negligent, that is, that the careless conduct of the plaintiff himself was the cause of and contributed to the injuries that *388he suffered. Now, if that is true the verdict should be for the defendant.’ At the conclusion of the charge the plaintiff objected and excepted to those parts of the charge as set forth above in which the court said the plaintiff must show that the defendant’s negligence was the sole cause of his injuries. The charge was full, correct and sufficient in all other respects.”

This portion of the charge does not appear to' relate to the burden of proof. But even if it be assumed that it did, the plaintiff saved no exception on that point.

No error of law is disclosed on this record. The charge as applied to the facts was in accord with the principles declared in Bilodeau v. Fitchburg & Leominster Street Railway, 236 Mass. 526, 539. The substantive law of negligence has not been changed by St. 1914, c. 553 (see now G. L. c. 231, § 85). Duggan v. Bay State Street Railway, 230 Mass. 370, 377, 378.

Exceptions overruled.
