OF AUSTRALIA. insane. The word "insanity' covers a field SO large as to be consistent with full responsibility for a given act. The proof, to amount to exculpation for sexual intercourse, must satisfy the tribunal that the aberration of mind was of such a nature and SO great as to render the person incapable of appreciating the nature and import of the act (see Yarrow v. Yarrow 1 ). If it was, then the act was not a volitional act of adultery.
The facts of this case, to my mind, establish that the respondent was an afflicted woman. Her mother was insane, The respondent inherited the trait. She has four times been interned in a lunatic asylum, twice as a girl, once since marriage, and again at the present time. I have no doubt from the evidence, particularly that of the doctor, that she is abnormal, that she is mentally deranged, that it is impossible to say at the best of times she is quite normal. I am also satisfied that during the time she was staying with Mrs. Ferguson she was at times quite insane, though at other times she recovered her usual approach to normality. I have, therefore, very anxiously considered how far the finding of the learned primary Judge as to this woman, incapable of defending herself now, ought to be sustained or altered. I have come to the conclusion that, granting all I have said and granting, for the sake of argument, the force of Mr. Davidson's very lucid contention that in the circumstances the burden lies on the petitioner of displacing the effect of the wife's general insanity, that burden has been sustained. I state the reasons why I
SO conclude.
When the petitioner, on 13th January, found his wife and the co-respondent together, she addressed him in terms that appear to be quite rational and the result of a determination, not momentary, and with a full appreciation of results. It is true that she was abusive, and that she did an extraordinary act of standing on a bed. But what weighs with me finally is this after the petitioner left the place where he found her and returned to Mrs. Ferguson's house, the respondent and the co-respondent came there, and apparently in cool blood said, in effect, that they had decided to make a confession. The confession was there and then written out by the co-respondent and
by the wife. Her signature is a free, well-written
