¶1Robert Ayers died at Omaha, Nebraska, August 1, 1906, a widower and without issue, leaving him surviving his sole heirs at law Charles Treadwell and Ezekiel Ayers, brothers, and Kate Addis and Fanny Inglis, sisters. He died seized of about $1,000 in personal property and an 80-acre farm in Clay county, where he had resided for many years. In 1892 he executed and deposited with the county judge of Olay county an instrument purporting to be his last will, which was in the words and figures following :
¶2“I, Robert Ayers, of Clay county, Nebraska, being of sound mind, memory and understanding do hereby make my last will and testament in manner and form following:
“First. If my beloved wife, Kate E. Ayers, be living at the time of my death, I give, devise and bequeath to her.all the real and personal property belonging to me wherever the same may be at the time of my death.
“Second. Should my wife, Kate E. Ayers, die previous to my death or before the proving of this will, it is my desire that after paying all just debts by me owing, that my property both personal and real be given to my niece, Gussie M. Inglis, daughter of my sister Fannie, wife of Alix Inglis of Victoria, Knox county, 111.
“In Witness Whereof, I, Robert Ayers, the testator, have to this my last will and testament set my hand and seal this 22d day of February, 1892.
“Robert Ayers. (Seal.)
“Signed, sealed, published and declared by the above named Robert Ayers as and for his last will and testament in the presence of us who have hereunto subscribed our names at his request as witnesses hereto in the presence of the said testator and of each other.
“L. S. Backus, of Harvard, Nebraska.
“Ezra Brown, of Harvard, Nebraska.”
¶3*18The probate of this will was contested by the sister Kate Addis and the brothers Charles Treadwell and Ezekiel Ayers. The county court overruled their objections to the will and admitted it to probate, and, an appeal being taken to the district court, a trial was had to the judge without a jury. Upon his finding in favor of the proponents the will was admitted to probate, and from this judgment the contestants appeal.

¶5The contestants admit that in other jurisdictions and in a dictum by this court the rule is stated to be that, where the attestation clause recites all the requirements of due execution and attestation, it will be presumed prima, facie that all the requirements existed. It is, however, insisted that this rule would be in violation of section 141, ch. 23, Comp. St. 1907, which proAides that, in case there shall be no contest to the probate of a will, the county court may grant probate thereof on the testi*19mony of one of the subscribing witnesses only, “if such a witness shall testify that such will was executed in all the particulars as required in this chapter, and that the testator was of a sound mind at the time of the execution thereof.” We do not think it necessary to determine this question. The testimony of the surviving witness we think established each and all of the facts recited in the attestation clause.
¶6The contestants argued that the testimony of Mr. Brown that Backus signed at Mr. Ayers request is to be disregarded as being a conclusion of the witness. There-was no objection to the form of the question which elicited this response, nor to the answer, at the time, and we do not understand the rule to be that the court may disregard testimony when it is received in that form without objection.

¶10The contestants produced a formidable array of witnesses, boyhood acquaintances of the deceased, his sister and brother, officers who had had charge of him while under restraint, and one or two medical witnesses beside Dr. Hay, then superintendent of the Nebraska insane hospital. The testimony of the latter was that he believed from the history he had of the case that the deceased in*22herited a strong predisposition to insanity; that he, without any apparent cause, had an attack of acute insanity in early life, and partially or wholly recovered, and had another attack, which was followed by others until he had in all five or six distinct attacks of acute insanity, in which he was either in a state of melancholia or a state of acute or subacute mania; that between these attacks there was a certain degree of sanity, but, judging from the character of most cases like his, the doctor asserted that after one or two attacks of acute insanity his mind was so weakened that he was never, probably, in a normal state after his first, second or third attack of that kind; that his disease was a form of periodic insanity called melancholic depressive insanity, which is an incurable constitutional disease. A long hypothetical question reflecting his life history as it was established or tended to be established by contestants’ evidence was propounded to the doctor, who gave in answer thereto the opinion that, while he would not speak positively as to the whole period, the deceased was certainly insane the greater portion of the time.
¶11On the other hand, the proponent produced the testimony of the scrivener of the will, of the men who had been appointed conservators for the deceased "when he was sent to the hospital, and neighbors and acquaintances who knew him more or less intimately at about the time of the execution of the will, the consensus of whose testimony was that he understood business affairs and was perfectly capable of transacting business.
¶12There is nothing in the record to show that his business ability or his understanding of business matters and affairs was ever directly affected even during the acute attacks. On the contrary, he seems to have always been accurate in his business methods, and careful and intelligent in his business transactions. Even at the last, while he was in Omaha, and when, as the testimony of his landlady tended to show, there were increasing aberrations of conduct which probably marked the progress *23of Ms disease, lie was careful and accurate about bis business transactions and capable of taking care of Ms business interests. She testified that be insisted upon having his board at a low price, and that he never forgot the date at which he began to board there nor when his payments were due, but invariably met the same according to his contract. The testimony of the contestants’ witnesses was directed to the point whether they considered him sane or insane, but not to whether he had sufficient mental capacity to comprehend the nature of, and conduct with ordinary prudence, business transactions. Even his sister, who contests the will, and testifies to the opinion that he was insane, upon the death of his mother purchased his interest in the land of his father, which had been set aside as his mother’s dower, taking his deed therefor, which was dated on the 2d day of April, 1891. If she understood insanity to mean a manifestation of a disease of the brain characterized by a partial derangement of one or more of the faculties of the mind, but which left her brother capable of looking after his business interests and transactions, then her testimony is consistent with her conduct; but, if she believed or meant that his mental faculties had been impaired to the extent that he was unable to properly care for his business interests, her conduct is altogether inconsistent with her testimony.
¶13This brings us to the crux of this case. The medical definition of insanity as given by Dr. Hammond in his work on Diseases of the Nervous System is a manifestation of disease of the brain characterized by a general or partial derangement of one or more of the faculties of the mind, in which, while consciousness is not abolished, mental freedom is perverted, weakened or destroyed. That, pathologically considered, the deceased was insane for many years may be admitted; but the real question is: Was his mind so diseased that his mental freedom was perverted and his understanding destroyed so that he was incapable of knowing and comprehending in a *24general way the natural objects of his bounty, the nature and extent of his estate and the distribution he wished to make of it. The older view regarded the human mind as a single indivisible potency not comprising distinct functions, and consequently that any impairment thereof must be absolute, and not partial. But modern medical science recognizes, as shown by the definition above quoted, that there may be a partial derangement of one or more of the faculties of the mind, leaving others practically unimpaired, and hence arises what is called partial insanity. This court has laid down the rule that, where the insanity is not general, the question to be determined is whether the subject was the victim of such delusions as controlled his actions and rendered him insensible to the ties of blood and kindred. McClary v. Stull, 44 Neb. 175. A very full discussion of the degree of soundness of mind required for the making of a valid will and a full citation of authorities will be found in the case of Perkins v. Perkins, 116 Ia. 253. The law makes no distinction between mental incapacity whether congenital or caused by age, sickness or disease, and it therefore follows that partial insanity does not necessarily disqualify a testator from making a valid will. Some courts have gone so far as to say that, when there is nothing unreasonable on the face of the will by one habitually insane, it will be presumed to have been made in a lucid interval. Kingsbury v. Whitaker, 32 La. Ann. 1055, 36 Am. Rep. 278. In this case there was nothing unreasonable upon the face of the will. He gave all his property to his wife if she should survive him. He had no children, and his next of kin were brothers and sisters. What his relations were with the mother of the niece whom he made his beneficiary or with his brother Ezekiel does not appear; but the other sister and brother testified in the case, and, judging from their testimony, there was nothing in their conduct toward this brother to keep alive fraternal affection or to cause them to be held in gentle remembrance by him. No reasons appear except *25the tie of blood from which it could be argued that he was under any obligation to any of his brothers or sisters, and we do not therefore regard it as strange nor unreasonable that he selected this niece as the sole subject of his bounty.
¶14There is a charge of undue influence, and the contestants complain of the rejection by the court of certain testimony of Mrs. Addis that Mrs. Ayers was embittered against her, the theory being that Mrs. Ayers influenced her husband to make a will hostile to Mrs. Addis. We think, if we assume that Mrs. Ayers was unfriendly to Mrs. Addis, the theory that she influenced her husband would have no support whatever. The only thread upon which this supposition is hung is that Ayers stated to the scrivener when he had drawn the will that his wife would now see that he had kept his word. This remark is fully explained by the fact that he had made a will in his wife’s favor, and it is more likely that he referred to some promise of that kind than to the contingent remainder which he left to the niece.

¶16We therefore recommend that the judgment of the district court be affirmed.
¶17By the Court: For the reasons stated in the foregoing opinion, the judgment of the district court is
¶18Affirmed.
