In the progress of the trial it became material to show that the subscription of the plaintiff’s name to a writing indorsed on a deed, was his genuine signature. A witness had testified that what purported to be the plaintiff’s signature to a bond endorsed upon a capias not connected with this action, was in his own proper bandwriting, and genuine. On the examination of the cashier of a bank, who had qualified as an expert, defendant’s counsel proposed to ask him to look at the signature on the capias and that to the writing endorsed on the deed, which was in evidence, and compare the handwriting. This the witness was allowed to do, despite the objection of the plaintiff.
Three reasons are given for excluding as incompetent a comparison by an expert witness, of a signature or writing not admitted to be genuine or connected with the case on trial, with a signature or writing, which has been offered in evidence, where the genuineness of the latter is drawn in question:
1. There is danger of fraud in the selecting of writings, offered as specimens for the occasion.
2. The genuineness of specimens offered may be contested, and thus numberless collatei*al issues may be raised to confuse the jury and divert their attention from the real issue.
3. The opposing party may be surprised by the introduction of specimens, not admitted to be genuine, and for want of notice may fail to produce and offer evidence within his reach, tending to show their spurious character. 1 Greenleaf, §§578 to 580; Fuller v. Fox, 101 N. C , 119; Outlaw v. Hurdle, 1 Jones, 150; Tuttle v. Rainey, 98 N. C., 513; Pope v. Askew, 1 Iredell, 16.
A comparison of handwriting is in some States permitted to be made by the jury or experts, and in others only by experts in the presence of the jury. Where a witness has acquired a knowledge of the person’s writing, he compares a *321disputed signature or writing with an exemplar in his own mind. But when he testifies as an expert he must first be furnished, as the basis of his testimony, with some specimen the genuineness of which may be insisted on before the jury. The law was finally settled in England (in 1854) by 17 and 18 Victoria, which provided that a disputed writing may be compared by witnesses in the presence of the jury with “a writing proved to the satisfaction of the Judge to be genuine,” and both may be submitted to the jury. It seems that there is no statute in any of the States which, like the English law, empowers the Judge to determine the quantum of proof necessary to establish the genuineness of another specimen placed in juxtaposition with the disputed writing. But there is a great diversity in the rulings of the Courts of the various States as to what is sufficient proof of the genuineness of a writing to constitute it a standard for comparison. In some of the States only specimens, admitted to be genuine, or filed as genuine by the party whose writing gives rise to the controversy in the records of the action involving it, are admissible as a criterion for testing the disputed writing, while in others it is competent to create a standard of comparison by offering proof of its genuineness. See 9 Am. and Eng. Ene., pp. 279 to 290.
In North Carolina it seems to be settled law that an expert in the presence of the jury may be allowed to compare the disputed paper with other papers in the case, wdiose genuineness is not denied, and also with such papers as the party whose handwriting gives rise to the controversy is estopped to deny the genuineness of, or concedes to be genuine, but no comparison by the jury is permitted. Pope v. Askew, 1 Iredell, 16; Outlaw v. Hurdle, 1 Jones, 150; Otey v. Hoyt, 3 Jones, 407; Yates v. Yates, 76 N. C., 142; Fuller v. Fox, 101 N. C., 119. It will appear from an examination of the authorities that, while this rule differs to some extent from that adopted or formulated by the Courts of other States, it seems never*322theless to be definitely settled. 9 Am. & Eng. Ene., p. 285, and note 4. The tendency now seems to be to authorize by statute a comparison by witnesses and juries of disputed writings with others, whose genuineness is to be established in some manner pointed out by the law.
The paper offered as an exemplar or standard of comparison purported to be a “ bond and capias, where the signature of Robert Tunstall had already been proven on the trial.” It does not appear, from the statement of the case, whether what purported to be the bond and capias purported also to be records of the Superior Court of Granville or of some other Court, but only that the “paper (capias, with bond endorsed) has no connection with this case.” Robert Tunstall had'not admitted the genuineness of the bond or capias, and it constituted no part of the record of the case on trial, nor are we informed where it purported to belong It does not appear whether Robert Tunstall’s name purported to have been written as an obligor or a witness to the bond, or as an officer who served and returned the capias, and it is obvious that we cannot declare that he was estopped to deny a signature, when we do not know to what it was appended. So that the genuineness of what purported to he the signature of Robert Tunstall, offered as an exemplar for the expert witness, was proven, if at all, only “by a witness” examined in the case. In Yates v. Yates, supra, the signature of one Eller to a deposition offered in evidence as genuine by one party, was compared by an expert wfitness, at the instance of the olher party to the action, with the disputed signature; and in Fuller v. Fox, supra, it was declared, in effect, that even that comparison could not have been made by the jury. “A jury is to hear the evidence, not see it.” Outlaw v. Hurdle, supra. It appeared, therefore, that the testimony offered, not being admitted to be genuine or connected with the case, was amenable to all of the objections mentioned by Mr. Green-leaf, supra.
*323"Where Courts have established the general rule that a comp u’ison of handwritings is to be excluded, the usual exception, as laid down by the highest authority (1 Wharton Ev., § 713), is that “when a writing, proved to be that of the party whose signature is in litigation, is already in evidence, having been put in for other purposes, then it is admissible to resort to this writing in order to determine the genuineness of the litigated instrument.” In support of this proposition Dr. Wharton cites cases decided in those Courts that have opened the door much wider than this for the allowance of such comparisons, even by experts. But applying even this rule to our case, it is not pretended that the bond and capias were offered or admitted for any other purpose than to compare the signatures of Robert Tunstall, or one of them, with that on the back of the deed. It is manifest that the rules adopted in most of the States prior to the passage of any Act regulating the comparison of handwriting, were, as mentioned by RodiiaN, J., in Yates v. Yates, supra, more liberal than that laid down by this Court. But we do not feel at liberty to disturb the settled practice. It is the province of the Legislature to determine whether it is best to alter or establish rules of evidence.
Both parties claim title under one Peter Hays, who, on the 6th of March, 1866, conveyed the land in dispute to the plaintiff Robert Tunstall. After the deed had been registered, the following endorsement purported to have been made: “I relinquish all my right and title to the within deed. March 10th, 1874.” (Signed by Robert A. Tunstall and witnessed1 by James Me. Hays.)
It was the genuineness of the signature of Tunstall so endorsed on the deed that was disputed on the trial. But if we suppose that the signature was admitted, or was proved to the satisfaction of the jury, to be in the proper handwriting of Robert Tunstall, it would remain to determine whether, in any view of the case, the feme defendant, would *324take as the devisee for life of Peter Hays. We think that the Court below erred in leaving the jury to pass upon the question whether Robert Tunstall was estopped by his own conduct from setting up a claim to the land in dispute. Nothing more appearing than that Peter Hays moved upon the land a second time in 1877, and was permitted to occupy it until his death in 1889 without paying rent, and that he paid the taxes during that period, these circumstances, taken ill connection with Tunstall’s declaration made to Peter Hays in presence of his wife, would not estop Tun-stall from claiming under a deed registered before the endorsement was placed upon it. Mrs. Hayes testified that the plaintiff told her husband, five or six years before his death, that he had never paid a dollar for the land and had no claim on a foot of it, and that he did not intend to claim it while Peter should live, or after his death. After this conversation, Peter continued to live upon the Jand just as before, and enjoyed the rents, paying nothing but the accruing taxes. His position was in no respect analogous to that of one who buys land at a public sale and pays his money for it, because he is assured by another that he has no claim upon it. As Peter Hays had been the beneficiary by the arrangement, there would be no difficulty about placing him in statu quo. Holmes v. Crowell, 73 N. C., 613; Bigelow on Estoppel, 484. The writing endorsed upon the deed cannot operate as a reconveyance of the legal and equitable estate in the land by Tunstall to Peter Plays, and his Honor was in error in submitting that view to the jury', whether a valuable consideration had been shown for executing the writing on the back of the deed, or not. Even a paper-writing in the form of a deed, but without a seal, would not have operated to reconvey the land, no matter what was the real intention of the parties. Avent v. Arrington, 105 N. C., 377. Unless the writing can be enforced as a contract to reconvey, we would be at liberty to say that the plaintiff, if a *325new trial should be awarded, must, in any event, recover, and we are confronted with the question whether it will be possible for the defendant on a new trial to set up the said endorsement as a contract to reconvey. The feme defendant, in her amended answer, relies upon the grounds, first, that the plaintiff by reason of the endorsement released and abandoned all interest in the land; secondly, that by his conduct dehors the conveyance or endorsement, he was estopped to set üp a claim under the deed. The Judge held that there was evidence of an estoppel in pais which he submitted to the jury, and they found that the plaintiff by his conduct was estopped. Conceding that his Honor erred in this view of the case, and admitting that the writing and signing of the endorsement, together with the undisturbed occupation of the land by Peter Hays after his marriage to the feme defendant in 1877, and until his death in 1889, without payment of rent, would not necessarily show an abandonment by him of his rights under the deed, could, the feme defendant, if she should hereafter demand in an ansiver. a specific performance of the agreement to reconvey (treating the endorsement as a contract) in any conceivable state of facts, establish her right in equity to such relief?
It is not essential, according to the construction given to our statute of frauds, that the consideration upon which one has contracted to convey land should be set forth in the written memorandum of the agreement to sell. Thornburg v. Masten, 88 N. C., 293; Ashford v. Robinson, 8 Ired., 114; Miller v. Irvine, 1 Dev. & Bat., 103. Therefore, if the language can be fairly construed as an executory agreement to convey the land described in the body of the deed, the consideration might be shown aliunde, and the defendant might ask a specific performance of the contract. When one person, moved by a sufficient consideration, declares a purpose to relinquish all of the right and interest that passed to him by virtue of the deed, on which the declaration is endorsed, *326and it appears that the attempted release is made upon consideration to the grantor by the grantee on the back of the conveyance in fee-simple, a court of equity is not bound to stick in the bark, and refuse its aid to compel a formal reconveyance to the original grantor. There can be no doubt that the land referred to in the writing was that admitted to have been fully described in the deed, and its identity is as clearly ascertained as if the description in the deed had been copied in the endorsement. The quantity of interest that he intended to relinquish was all of his right and title in a piece of land that Peter Hays had conveyed to him in fee simple. The physical connection between the deed and memorandum is sufficient to make it valid, as the description of the subject-matter and of the quantity of interest, by the reference to the deed. 8 Am. & Eng. Enc., 712; Mayer v. Adrian, 77 N C, 83.
In Beattie v. Railroad, 108 N. C., 429, it was'held that an instrument of writing signed, but not sealed, in which one agreed to relinquish to a railroad company the right-of-way over such route as might be fixed and ascertained by a survey through his land, was such a contract as a court of equity would have enforced by decreeing a specific perf am-anee, had the company completed its line within reasonable time and before the presumption of abandonment had arisen from non-user. .There, the identity of the right-of-way was to be established by the survey and location of the line, as in our case, by reference to the description in the deed. In that case “ the right-of-way ” would have been construed to mean the easement provided for in the charter. It is evident from the language that the parties intended that whatever title Robert Tunstall had in the land should be “relinquished” to Peter Hays, and if any consideration passed for that agreement, the Courts should compel him, upon a proper demand for such relief, to convey all of his right and title to those who take under the will of Peter Iiays, accord*327ing to their several interests. In Linker v. Long, 64 N. C., 296, PearsoN, C. J., after stating that it was properly conceded on the argument that the endorsement on a deed, “ I transfer the within deed to W. E. T. again,” did not amount to a reconveyance, said, for the Court: “ The only effect that can be allowed to this writing is that it furnishes evidence of an agreement to reconvey, which a court of equity will enforce by a decree for specific performance, provided it be supported by a valuable consideration.” It is obvious, then, that if a valuable consideration is shown to have passed, the writing, though insufficient as a release, may be enforced as a contract to reconvey. What particular circumstances were relied upon by counsel to show the payment of the notes assigned by Fuller, or that any other consideration passed from Peter Hays to Robert Tunstall, it is not necessary that we should enquire. We take it for granted that all available testimony tending to show a consideration will be adduced on another trial. It is sufficient now to declare there was error in the charge in holding that there was.evidence to go to the jury of an estoppel in pais, or of an actual release or reconveyance, as well as in the admission of testimony as to the comparison of handwriting, for which a new trial is awarded.
