¶3The capacity necessary for the making of a will and that required for the making of a deed are not identical. If one is wholly without reason or understanding, he can not make either a deed or a will. But. the test and measure of testamentary capacity is not the same as that of contractual capacity. A man may be incapable of making a will, a deed, or a contract, but a common standard can not be fixed in reference thereto. Some courts have held that it requires more capacity to make a will than a contract, some the same amount, and some less: The last is the more common statement. Possibly proof of contractual capacity may furnish prima facie evidence of testamentary capacity. Our own code declares that “An incapacity to contract may coexist with a capacity to make a will,” Civil Code, §3268.
¶4In Page on Wills, 112, it is said: “This divergence of judicial opinion is, of itself, enough to suggest the view that is undoubtedly the true one, and that now obtains by the' weight of authority. This view is that testamentary capacity and contractual capacity are so different in their nature that it is. impossible to use one as a test for measuring the other, or to say that the existence of one either proves or disproves the other’s existence conclusively.”. See also Gardner on Wills, 106 ; Slaughter v. Heath, 127 Ga. 747, 749-751 (57 S. E. 69). On the subject of capacity to make a deed, it is said in Devlin on Deeds (2d ed.), §69 : “If *759the grantor has sufficient mental ability to comprehend what he is doing, and to understand the nature of his act, his deed must be deemed that of a sane person.” And see section 67 et seq. In Richardson v. Adams, 110 Ga. 425, 427 (35 S. E. 648), Chief Justice Simmons, in referring to a ease where a very old man in feeble health made voluntary deeds to certain of his children, grandchildren and great-grandchildren, and seemingly wished by such conveyances, in a sense, to become the administrator of his own estate, said; “Speaking for myself, I think that in such a case the mental capacity of the grantor should be measured.by the rule laid down in the books as applying in cases of wills.” This was said in discussing the case, and was not a formal ruling. While the facts may be such as to make an effort on the par.t of an aged and infirm person approaching his end, by voluntary deeds to provide for the disposition'of his estate, very similar to the situation of one making a will, yet, it is of doubtful propriety in terms to charge that the measure of testamentary capacity is applicable as a standard to capacity to make a deed. To do so involves an inquiry into whether the deeds were voluntary, what was the condition of the man, and whether his purpose was in effect to administer his own estate. It is better to let the capacity to do a particular act be measured by the standard applicable to that act, and not by the standard applicable to some other act. But it is not error, in instructing the jury as to the mental capacity necessary for the making of a deed, to refer, by way of illustration, to that required for the making of a will. Here the presiding judge informed the jury that the two were not necessarily the same, that generally the capacity to make a will did not include the capacity to make a deed, but that testamentary capacity might coexist with a lack of contractual capacity, though he was of the opinion that, if the disposition of property was “in the nature of a will,” the capacity required would be the same as for the making of a will. No exception was taken to this last statement, and we do not hold whether there was any error in it or not. If the correct rule be applied, illustrations of mental capacity in regard to other subjects will not constitute error, unless so given as to be calculated to confuse or mislead the jury. In Boughton ¶. Knight, L. R., P. and D. 64, Sir J. Hannen delivered a most interesting charge on the 'subject of insanity and testamentary capacitjq and illustrated the mean*760ing of the term by reference to the criminal law, the law of contracts, the capacity to, give testimony, and insanity as affecting marriage; but these ’ illustrative references were clearly given so as to aid rather than confuse the jury. The learned judge arrived, at a somewhat different conclusion from the rule in this State, stating that he thought it required more mental capacity to comprehend a general scheme of distribution of an estate than to understand a single transaction. Under our exceedingly strict law, prohibiting any expression or intimation of opinion by the presiding judge, he has not the same freedom of summing up in this State as in England; and the decision cited is only referred to passingly as one where the use of illustrations well put were calculated to aid the jury in understanding the subject in hand. Illustrations which are apt and clearly made, and not so extended as to withdraw the attention of the jury from the issue to be determined, are not generally erroneous, and may sometimes be beneficial. Illustrations which are inapt or irrelevant, or are so made as to confuse or mislead the jury, are to be avoided. Illustrations of the latter class shed darkness upon a case rather than light. In the present case an examination of the entire charge satisfies us that the charges complained of on the subject of testamentary capacity were not such as to injure the defendants, or to require a reversal.
