1. (a) "A new trial may be granted in all cases when the presiding judge may . . . refuse to give a pertinent legal charge in the language requested, when the charge so requested shall be submitted in writing." Code, 79-207.

(b) Where there has been a substantial compliance with the written request, the charge has been held to be sufficient, but the refusal to give a pertinent legal charge in the language requested has generally been held erroneous where there is no substantial compliance with the written request.

(c) If the request to charge is specific, so must the charge be specific; if the request itself embodies only an abstract principle, so may the general charge be abstract.

(d) Where in the general charge the principle invoked is not just as plainly and understandably expressed and concretely related to the facts of the case as it is related in the request presented, the mere matter of words not being controlling, a new trial may be granted.

2. The request to charge set out in special ground 1 of the amended motion for a new trial is not a correct statement of the law for the reasons stated in the opinion, and the trial court did not err in refusing to charge such request. 3-6. The remaining special grounds are without merit for the reasons stated in the opinion.

E. D. Ridley was indicted for murder and convicted of involuntary manslaughter in the commission of an unlawful act. His motion for a new trial, based on the usual general grounds and six special grounds, was overruled and he excepted. This is the second appearance of this case in this court. See Ridley v. State, 81 Ga. App. 737 (60 S. E. 2d, 249).

'If you do not believe beyond a reasonable doubt that the defendant is guilty of the offense of murder, or voluntary manslaughter or involuntary manslaughter in the commission of an unlawful act, or involuntary manslaughter in the commission of a lawful act, but without due caution and circumspection, or if there is a reasonable doubt in your minds as to his guilt on any of these charges, it would be your duty to acquit him. In that event the form of your verdict would be: "We, the jury, find the defendant not guilty." ' The above quoted four excerpts from the charge of the court contain every expression of the court in his charge to the jury in reference to the offense of involuntary manslaughter in the commission of a lawful act without due caution and circumspection. The court, nowhere in his charge to the jury, instructed the jury as to what constituted or what acts would constitute the offense of involuntary manslaughter in the commission of a lawful act without due caution and circumspection, so that the jury could determine whether or not under the facts of this case the offense constituted involuntary manslaughter in the commission of a lawful act without due caution and circumspection."

When this case was formerly before this court ( Ridley v. State, supra), it was held that the trial court committed reversible error in not charging on the law of involuntary manslaughter in the commission of a lawful act without due caution and circumspection. The evidence adduced upon the subsequent trial, presently under consideration, is not materially different from what it was on the former trial and the court in the trial here under consideration charged on the law of voluntary manslaughter in the commission of a lawful act without due caution and circumspection as has been stated above.

The request to charge, which we have quoted above, is a correct and pertinent legal charge under the evidence. Warnack v. State, 3 Ga. App. 590, 596 (60 S. E. 288); Dorsey v. State, 126 Ga. 633, 634 (55 S. E. 479). When the request to charge is in writing, is legal and pertinent, the court should give it "in the language requested" (Code, 70-207); or at least should, as has been often held by the Supreme Court, give it substantially as requested. Ocean Steamship Co. v. McAlpin, 69 Ga. 437, 440. The refusal to give a legal, pertinent charge in the language requested has generally been held erroneous unless there was a substantial compliance with the request, but in the case of a substantial compliance it has been deemed and held sufficient. Werk v. Big Bunker Hill Mining Corp., 193 Ga. 217, 236 (17 S. E. 2d; 825). "What must have been intended by the phrase 'in the language requested'? In the law, we are simply trying to get at the substance of things regardless of form. Language is only the means of expressing thought or feeling, and is thus a mere form or vehicle. This statute therefore must have been concerned with the thought or principle to be expressed, and not with the mere mode of expression. So it was evidently not its purpose to require a charge even in words of similar form or structure, where in the general charge the principle invoked is just as plainly and understandably expressed, and as concretely related, as in the request presented; the mere matter of words not being controlling." Werk v. Big Bunker Hill Mining Corp., supra, at page 240. "Stated differently, if the request is specific, so must the charge be specific; if the request itself merely embodies an abstract principle, so may the charge be abstract." Werk v. Big Bunker Hill Mining Corp., supra, at page 239. "The court is not bound to charge in the exact language of the request; and a new trial will not be granted for refusing to charge as requested, when the charge given substantially covers the request, which request was not more specific in its application than was the charge as given." Brown v. State, 195 Ga. 430 (1) (24 S. E. 2d, 312). But a new trial will be granted for refusing to charge a correct and pertinent legal request where in the general charge the principle invoked is not just as plainly and understandably expressed and as concretely related in the charge as given as in the request presented, "the matter of words not being controlling."

Where, as in the instant case, the request is a correct and pertinent legal one and is more specific in its application than the charge as given and the charge as given was not given substantially as requested, a new trial is required. The general charge did not deal specifically with the law while the defendant was justified in striking the blow or blows with his fist or his shoe, which resulted in the death of the deceased, and yet could be found guilty of involuntary manslaughter in the commission of a lawful act without due caution and circumspection; and he, having been convicted of the higher offense, must be granted a new trial.

2. In special ground 1 the defendant contends that the court erred in refusing to charge the following written request: "I charge you that if you should find that under all the circumstances as they are shown to leave existed at the time by the evidence in this case, giving to the defendant's statement due credit, that E. D. Ridley had a right to prevent Basil Cox from assaulting him, even though E. D. Ridley thought that Basil Cox intended only to assault and beat, and not to seriously injure him, and that E. D. Ridley, under such circumstances, without the intention to kill Basil Cox, did strike and kick basil Cox about the head, face and body, inflicting upon Basil Cox wounds which resulted in the death of Basil Cox, then under such circumstances you might convict the defendant, E. D. Ridley, of the offense of involuntary manslaughter in the commission of a lawful act, without due caution and circumspection, but you would not be authorized under such circumstances to convict the defendant of either of the offenses of murder, voluntary manslaughter, or involuntary manslaughter in the commission of an unlawful act."

The trial court in effect followed the suggestion frequently made by this court and the Supreme Court that the best practice of conveying the defendant's statement to the jury is to use the language of Code 38-415 without elimination, transposition, or amendment ( Millen v. State, 175 Ga. 283, 288, 165 S. E. 226), and there leave the matter ( Collins v. State, 66 Ga. App. 325, 329, 18 S. E. 2d, 24; Morgan v. State, 119 Ga. 566, 46 S. E. 836).

"The jury trying a criminal case are sworn to give a true verdict according to evidence. It is important for them not to confound the prisoner's statement with the evidence or the evidence with the statement. The statute allows them to give the statement such force as they think proper, and even to believe it in preference to the sworn testimony. In charging them the court should keep the evidence distinct from the statement and shape the general tenor of the charge by the evidence alone and the law applicable to it. For if the court should mingle evidence and statement together, the jury might find it difficult to separate them and might fail to understand the import of the instructions delivered from the bench. At some stage of the charge the statutory provisions touching the statement ought to be made known to the jury, and this as has frequently been suggested by this court, is usually enough to say touching the statement. The statute on the subject is so plain and explicit as to need no exposition or comment. If, however, a special request to charge on any matter of defense set up in the statement is made in writing, the request ought to be granted when the charge requested is applicable to the matter of the statement and expressed in appropriate terms. This is the best method of conducting the somewhat complicated and anomalous system of trial which prevails in this State in consequence of the statutory privilege of annexing unsworn statement to sworn testimony. The statement may have the effect of explaining, supporting, weakening or overcoming the evidence, but still it is something different from the evidence, and to confound one with the other either explicitly or implicitly, would be confusing and often misleading. The jury are to give the statement such force as they think proper. Its rightful force may be either against the prisoner or for him, or it may be entitled to none whatever. The jury are to deal with it on the plane of statement and not on the plane of evidence, and may derive from it such aid as they can in reaching the truth." Vaughn v. State, 88 Ga. 731, 738 (16 S. E. 64).

In the instant case the defendant in his request to charge mingled the defendant's statement and the evidence together and enjoined the jury to give the defendant's statement "due credit," when, under the law, the jury was not required to give the defendant's statement any credit whatsoever if it did not desire to do so. The defendant did not see fit to use the language, "where the evidence and the defendant's statement, taken together," etc., which is the language used in Warnack v. State, 3 Ga. App. 590 (2) supra, one of the cases upon which the request is based; nor do we think that the defendant used language of like significance or import, and the jury might have found it difficult to separate them, and might have failed to understand the import of the requested charge if it had been given. The request being subject to this imperfection, the court did not err in refusing to give it in charge.

Moreover, the court charged what facts, upon the proof of which, the jury would be authorized to find the defendant guilty of murder, voluntary manslaughter, involuntary manslaughter in the commission of an unlawful act, and involuntary manslaughter in the commission of a lawful act without due caution and circumspection; and the court charged what facts, upon the lack of proof of which, the jury could not find the defendant guilty of any of these crimes. There was no request to charge more specifically upon the first three of the four crimes listed above, but, as to the last of such crimes, the defendant presented the written request here under consideration. The last clause of the request stated, "but you would not be authorized under such circumstances to convict the defendant of either the offense of murder, voluntary manslaughter, involuntary manslaughter in the commission of an unlawful act." The request left out what proof the lack of which would authorize the jury to find the defendant not guilty of murder, voluntary manslaughter, involuntary manslaughter in the commission of an unlawful act, and in the same breath told the jury it could find the defendant guilty of involuntary manslaughter in the commission of an unlawful act without due caution and circumspection. As to the guilt, if any, of the defendant of any one of the four crimes listed above, it was a question of fact which should have been left to the jury for their consideration alone, unaided by the court's indulging in such specific inferences of fact ( MacDougald Construction Co. v. Mewborn, 34 Ga. App. 333, 338, 129 S. E. 917; Standard Cotton Mills v. Cheatham, 125 Ga. 649, 54 S. E. 650); and we think that it was a proper exercise of the judgment of the trial court to determine that the request, if given, would have misled the jury as to the true meaning of the case. Long v. State, 12 Ga. 293, 323; Harrell v. State, 121 Ga. 607, 611, supra.

"The court may not indicate a specific inference of fact, however potent it may be in determining the question at issue. Under this rule the court exceeds its privileges where it attempts to instruct, as a matter of law, that the existence of one fact depends upon the existence of another." Reid's Branson, Instructions to Juries, Vol. I, p. 45, 20, footnotes 93 and 94. The requested charge was a hypothetical statement by way of instructions and was insufficient because it ignored some of the facts necessary to be found as a basis for the request. Standard Cotton Mills v. Cheatham, supra; Southern Railway Co. v. Wilcox, 59 Ga. App. 785, 791 (2 S. E. 2d, 225); Lacey v. State, 154 Ala. 65 (45 So. 680). It was not, therefore, error for the trial court to refuse to give the requested charge.

3. "Where a judge gives in charge to the jury the general principles of law applicable to an issue in the case, a party who desires more specific and concrete instructions as to one of his contentions should make the request therefor in writing." Byrd v. Grace, 43 Ga. App. 255 (158 S. E. 467), Applying this rule to the charge which special ground 2 alleges should have been given, the refusal or failure to charge was not error.

4. The refusal of the requests to charge relative to the weight of positive and negative testimony, as complained of in special grounds 4 and 5, was not erroneous, as both requests are open to the criticism that each failed to instruct the jury that, in weighing the testimony of each witness, the rule stated in the requests applies only when the witnesses are of equal credibility. Great American Indemnity Co. v. Oxford, 68 Ga. App. 884, 886 (24 S. E. 2d, 726); Moore v. State, 57 Ga. App. 287, 289 (195 S. E. 320).

5. The court is not required to charge in the exact language of the request; and here, while the words of the request which the court refused to give are not in form or structure similar to the charge which was given, yet the principles invoked in this request are just as plainly and understandably expressed and concretely related in the charge given as in the request; and mere words not being controlling, the court did not err in refusing to charge the request set out in special ground 6. Brown v. State, 195 Ga. 430, supra; Werk v. Big Bunker Hill Mining Corp., 193 Ga. 217, 240, supra.

6. Since the case must be remanded for a new trial for the reason stated in division 1 of this opinion, and since we cannot be sure what evidence will be presented on the new trial, the general grounds of the motion are not considered at this time.

Judgment reversed. Gardner and Townsend, JJ., concur.
