from the evidence, however, that he committed the offense. The only -substantial ground urged for reversal on this appeal relates to the court’s instructions to the jury on the defense of insanity.3
Considerable testimony was offered relating to that defense. Appellant’s family and acquaintances testified to numerous incidents of erratic conduct, including frequent outbursts of exaggerated and purposeless violence. A psychiatric witness for the defense testified that in his opinion appellant was suffering from a manic depressive psychosis at the time of the crime and that, although he probably knew right from wrong, he was unable to control his conduct in the light of such knowledge. On the other hand, it was the opinion of two psychiatrists who testified for the Government that, although appellant was of very limited intelligence, approaching or within the feeble-minded range, he had no psychosis or neurosis, was able to distinguish between right and wrong and was not under the pressure of an irresistible impulse.
The court properly instructed the jury on the “right-wrong” and “irresistible impulse” tests which prevailed when this case was tried.4 But it also instructed,
“Now, have in mind, ladies and gentlemen, that the law does not recognize as insanity a mental disorder unless it is a real mental disease.
“There are many people who are psychopathic to one degree or another; they are maladjusted; emotionally unstable; resentful, for one reason or another, of society; of low intelligence; indifference [sic] toward the rights of others, and so on. That is a psychopath. He is not insane within the meaning of the law; he is simply an abnormal, maladjusted, person, or subnormal, as the case may be; he is a misfit; he does not care about others; indifferent to them, and so on. You must distinguish in your mind between that kind of mental disorder, because it obviously is a mental disorder, and a real mental disease.
“The man who is in this court, as a defendant in a criminal case, time and time again, is an extreme example of what I am talking about. There is something wrong with his mind or he woud not do it in the first place, but it does not follow that he is insane.
“The kind of mental disorder I am talking about is a mental disease, just as I said before and as counsel on both sides have described it.”
Read alone, the court’s attempted distinction between “mental disease” and “mental disorder” was at least confusing. Read in the light of one explanation offered by the record, it is plainly erroneous. This explanation appears in the court’s remarks, made during the trial and in the presence of the jury, that in criminal cases the question is whether the accused has a “mental disease, as distinguished from a mental disorder — not a pathological mental disturbance but a physiological one And it appears again when the court later asked the defense psychiatrist whether appellant “was suffering from a ® physiological mental disease, as distinguished from a pathological condition

There is no merit in appellant’s contentions that the trial court erred in denying his motion for severance from the trial of his wife and brother-in-law, charged as accessories, and in admitting their confessions containing implications against him. Severance normally is a matter for the discretion of the trial judge, and a denial thereof will not be upset on appeal unless amounting to an abuse of discretion. Wheeler v. United States, 1947, 82 U.S.App.D.O. 803, 165 F.2d 225, certiorari denied,
1948, 333 U.S. 829, 68 S.Ct. 448, 92 D.Ed. 1115. We find no abuse of discretion here.

The tests prevailing when appellant was tried have since been broadened. Durham v. United States, 94 U.S.App.D.O. —, 214 F.2d 862.
