The first assignment of error is the refusal of the court to give the sixth' special instruction asked by the defendant.
The defendant requested the following instruction: “ That this being a case of circumstantial evidence, the jury cannot legally find that the fracture of Donahoe’s skull was caused by an injury inflicted by the defendant, unless [they find, that there is no possibility of reasonably accounting for such fracture by accident.”] The court refused to give this in the above terms, but instructed with the following change of the words in brackets, “ unless they find that there is no reasonable probability that such fracture was caused by accident.”
In charging a jury the court is not limited to language *119adopted by the party requesting instructions. This lias been held by this court in several instances. If there is any real difference in the -above modes of expression, -that of the court is the most nearly correct, for the terms “ no possibility,” used by the defendant might warrant an unfounded assumption which would be clearly erroneous.
The second assignment is to the refusal to give the eighth and ninth instructions requested by the defendant, and assuming to decide from the evidence that they had no application to the case.
One of these instructions was, in substance, “That if the jury believe from' the evidence that the defendant was first attacked by the deceased, under circumstances such as furnish reasonable grounds for apprehending a design to do the defendant a great bodily harm, and he had reasonable grounds for believing the danger imminent although it was not so in fact, then the defendant was justified.”
The other instruction requested was, in substance, “ That if the jury believe that defendant through fear, alarm, or cowardice inflicted a mortal blow upon the deceased, under the impression that great bodily injury was about to be inflicted upon him by the deceased, although he ivas really in no great danger of bodily harm, it is neither -murder nor manslaughter,” &c.
It is in the province of the court to determine whether there is foundation in the evidence for any particular instruction to the jury.
At the same time it is true that the court is not to be governed by the degree of evidence, but should give the instruction if there is any basis for it to stand upon. But it has been repeatedly decided by this court, that an instruction, though correct in law, should be refused unless the evidence or the pleadings show it to be pertinent, and that there is a basis for it in the facts of the case. Beebe v. Stutsman, 5 Iowa 271; Gover v. Dill, 3 Ib. 337; Conger v. Dean, lb. 463; Abbott v. Striblen, 6 Ib. 191.
The bill of exceptions professes to contain “ all the testi*120mony in regard to tbe infliction of tbe injury committed upon Donahoe,” and from tbis we are of tbe opinion that tbe court ruled correctly in rejecting tbe instructions, for they assume that there is evidence touching this point, Avbilst in fact there is none at all indicating an attack or a threat by the deceased on tbe defendant.
Tbe third error assigned is, that the jury was not sworn to render a verdict according to the law and evidence, but only, as the defendant objects, according to the evidence. This assignment is based upon a mistake of fact, for the record states that they were sworn to try the case “ according to the evidence given them before the court, and the laws of the State.”
Therefore, thei'e being no error found in the judgment or proceedings, the judgment of the District Court is affirmed.
