¶1Appellant, being the administratrix of her husband’s estate, filed a claim against said estate, founded on what purported to be a certificate of deposit executed to her by her husband, a private banker, which instrument is as follows: “$1,300. Knox, Indiana, January 13, 1892. The Knox Bank of Alexander H. Henderson. Mrs. Elizabeth Bickel has deposited in this bank $1,300, payable to the order of Mrs. Lou M. Henderson in current funds, on demand, on the return of this certificate properly indorsed. Alex. H. Henderson.” The *668court, not being satisfied with the correctness of the claim, under the provisions of §2476 Burns 1901, Acts 1883, p. 151, §9, appointed Mr. Courtwright, a practicing attorney, to represent the estate.
¶2The only questions sought to be presented by the appeal arise on appellant’s motion for a new trial, and are, (1) the action of the court in permitting and in refusing certain testimony to go to the jury; and (2) in the giving and in refusing to give certain instructions to the jury.

¶4*669The purpose of a cross-examination is to sift the testimony of a witness, and separate that which is true from that which is false or misleading; and trial courts have a wide discretion in allowing questions reasonably addressed to these ends, and more especially along lines incapable or impracticable of proof by other evidence. We think it is everywhere acknowledged that within proper bounds, to be controlled by the court, a witness on cross-examination may be questioned concerning his antecedents, as affecting his credibility; and for the same purpose, as a general rule, questions which tend to develop the motive, bias or interest of the witness should be allowed. It is therefore only where there has been an obvious abuse of discretion in the trial court that this court will interfere. Shields v. State (1897), 149 Ind. 395, 402; Bessette v. State (1885), 101 Ind. 85; Wachstetter v. State (1885), 99 Ind. 290, 295, 50 Am. Rep. 94; Chicago, etc., R. Co. v. Barnes (1894), 10 Ind. App. 460; 2 Elliott, Evidence, §908; 1 Wharton, Evidence, §§544, 545.

¶6The record discloses unusual caution by the counsel for appellant in limiting the direct examination of her best-informed and most important witness, and their caution in this regard may have furnished the court the justification, under the circumstances of the case, for an enlarged license *670in. cross-examination. At all events, in a careful review of the evidence, we are convinced that no reversible error was committed in allowing the questions.

¶9*6715. No question is presented on instructions for noneompliance with the fifth subdivision of rule twenty-two, which reads thus: “A concise statement of so much of the record as fully presents every error and exception relied on, referring to the pages and lines of the transcript. If the insufficiency of the evidence to sustain the verdict or finding, in fact or law, is assigned, the statement shall contain a condensed recital of the evidence in narrative form so as to present the substance clearly and concisely. The statement will be taken to be accurate and sufficient for a full understanding of the questions presented for decision, unless the opposite party in his brief shall make necessary corrections or additions.” Under the statute but one copy of the record, in an appeal, is filed in this court; and, it being impracticable in the reasonable dispatch of business for each judge of the court to take such record for personal examination before a final disposition of the cause, it was deemed necessary to adopt some plan whereby the judges may reach an accurate knowledge of the record without an examination of the original. The plan adopted, as outlined in rule twenty-two, requires that in the preparation of his brief the appellant, among other things, shall make a concise statement of so much of the record as fully presents every error and exception relied on; that is to say, his brief must present a concise—not a full—statement of every part of the record that is essential to a full presentation of every question relied upon for reversal. A brief so constructed enables each member of this court, in reading the brief and considering the case in his chambers, to act as intelligently upon the questions involved as if he personally had the original record before him. The question of the rule, however, is no longer one of expediency. Magnuson v. Billings (1899), 152 Ind. 177; Cleveland, etc., R. Co. v. Stewart (1903), 161 Ind. 242; State, ex rel., v. Lankford (1902), 158 Ind. 34; Boseker v. Chamberlain (1903), 160 Ind. 114; Harrold v. Fuenfstueck (1903), 31 *672Ind. App. 275; McElwaine-Richards Co. v. Wall (1902), 159 Ind. 557. Appellant has made no effort to comply with the rule beyond stating that the court erred in giving number three of its own motion, and for refusing to give numbers one, two, three, four, five, six and eight tendered by appellant, and in addition a brief statement, not of the contents or substance of the instructions, but his opinion of their legal effect. In testing instructions, the legal effect is to be determined by the court from the language used, and not by the opinion of counsel. For failure to comply with the fifth subdivision of rule twenty-two, we must hold that no question arises upon instructions.
¶10There is by no means such a failure of evidence to sustain the verdict as will warrant us in disturbing it.
¶11Judgment affirmed.
