Error is alleged in the denial of the defendant's motion for a new trial after a hearing on his competency to stand trial because of narcotics addiction. The motion was heard approximately eleven and one-half months after the original trial. A doctor appointed by the court testified that in his opinion while the defendant was "appreciably impaired," he was "not impaired to the degree that he was unable to defend himself or assist his attorney." Although the doctor did not observe the defendant at the time of his trial, and the defendant himself testified at the hearing on the motion for a new trial in effect that he was unable to defend himself or assist his attorney, the judge could have disbelieved the defendant and given weight to the testimony of the doctor, which he evidently did. "The motion for a new trial is usually a matter for the trial judge's sound discretion." Earl v. Commonwealth, 356 Mass. 181, 184. Commonwealth v. Dascalakis, 246 Mass. 12, 25, 32. There is no abuse of that discretion here.

Judgment Affirmed.

This action of contract on an insurance policy is before us for the second time. The facts may be found in Beacon Textiles Corp. v. Employers Mut. Liab. Ins. Co. of Wisconsin, 355 Mass. 643. There we sustained the plaintiff's exceptions to rulings made on the defendant's requests, but did not order judgment for the plaintiff because "as inferences would have been required to establish the plaintiff's liability to its customer, we . . . [were] unable to say that the only issue presented on the record . . . [was] the construction of a written instrument." P. 647. On retrial, the trial judge, sitting without jury, made the following findings: "[T]here was no accidental injury to the yarn while it was in the possession of the plaintiff. The burden of proof rests upon the plaintiff to prove its liability to its customer. The plaintiff failed in that burden of proof. There was no evidence as to when or what caused the yarn to become defective." A finding for the defendant was entered. The plaintiff claims exception to the denial of its requests for rulings. There was no error. To sustain its burden, it was necessary for the plaintiff to establish that the yarn was defective before it was delivered to its customer. The defendant admitted, in its answers to interrogatories, that a textile research firm employed by it had ascertained that this was so. However, the written report of that firm, introduced in evidence by the plaintiff, does not in fact establish that proposition. Furthermore, the plaintiff's sole

witness, its treasurer, testified that the yarn was not discolored when it left the plaintiff. Hence, the trial judge was not concluded by the defendant's answers to interrogatories from making the above findings. Dome Realty Co. v. Cohen, 290 Mass. 36, 39. Tighe v. Skillings, 297 Mass. 504, 507. The judge properly denied requests for rulings which were inconsistent with the wholly warranted findings.

Exceptions overruled.
