after stating the case: We cannot agree with the learned counsel of the defendant that this case bears any • resemblance to Summerlin v. Railroad, 133 N. C., 550. In that case the questions excluded by the Court were so framed as to require the witnesses to express an opinion as to the •existence of a fact which was controverted, and it was there said by the -Court that this was not the proper form for the ■question to take, but that the expert’s opinion should be founded upon a hypothetical question containing a statement •of facts which the jury might find from the evidence, and supposing, of course, that they will find them to be as stated in the question. The rule is stated in 3 Wharton & Stille’s Medical Jurisprudence (5th Ed.), p. 580, as follows: “An opinion that an" injury resulted from a certain designated act, being the one upon which the action, is based, as distinguished from an opinion that certain causes would produce certain results, is improper as usurping the province of the jury.” And so did we say, substantially, in Summerlin v. Railway, upon the authorities therein cited. The same rule, practically, is stated in 6 Thompson on Negligence, sec. 7755 (p. 694), as follows: “A medical expert is generally allowed to state his opinion as to whether the injury for which the action is brought might have resulted from a particular cause.” But in this case the witness was not asked to give an opinion as to the mere existence of a controverted fact, but, upon the assumption that the jury found certain facts from the evidence us to the symptoms of the plaintiff’s disease, including the fact that he had been injured by the jar in the manner described, he was asked to give his scientific opinion as to what produced those symptoms. He answered that the kidney had been permanently dislocated by the fall, and that he would be disabled for life, unless the kidney was removed by an operation. The injury from the jar, and the marked symptoms immediately following it, were assumed as facts that the jury might find to have existed, and his opinion was based on the facts so to *128be found. He was not asked, if the symptoms existed, what particular injury caused them, but the injury and its instant manifestations were first assumed as established, and his opinion was deduced from these supposed ascertained facts. It was necessarily assumed by the very form of the question that whatever injury the plaintiff had suffered was directly caused by the fall, and the witness was called upon to state what the physical conditions produced by the fall indicated to his trained and experienced mind as a medical practitioner. We think the evidence comes strictly within the rule admitting expert testimony, or that which is given by a witness having special or peculiar knowledge and skill in the particular calling to which the inquiry relates, and the competency of the question, as predicated on the hypothetical facts stated, is sustained by the best-considered authorities. Longan v. Weltmer, 180 Mo., 322 (64 L. R. A., 969) ; Stouter v. Railway Co., 121 N. Y., 661; Perkins v. Railroad Co., 44 N. H., 223 ; State v. Bowman, 78 N. C., 509. The question was not so put to the witness “as to require him to draw a conclusion of fact nor to pass upon the effect of the evidence in proving controverted facts,” but merely to express his opinion upon the facts stated in the question, leaving them to be found exclusively by the jury. There was evidence upon which the jury could have made such a finding.

The ruling of the Court in admitting the evidence of Dr. Léwis was, therefore, correct.
