=Ordinary Care and Skill Only Required.=—The leading cases in America on the subject of civil liability for malpractice are: Leighton _v._ Sargent, 7 N. H., 460, and Carpenter _v._ Blake, 60 Barb., 485 (s. c. on appeal, 75 N. Y., 12). In the former case the Court said: “In a science encumbered with so many sources of error and difficulties, it is obvious what cause we have for proceeding with the utmost caution, and for advancing from step to step with the greatest circumspection. It is in consideration of those peculiar difficulties that beset and encompass the physician and surgeon, that all enlightened courts have held that but ordinary care and skill shall be required of them, and that mere errors of judgment shall be overlooked, if the general character of treatment has been honest and intelligent, and that the result of the case shall not determine the amount of the responsibility to which he is held; and that when unskilfulness or negligent treatment of his patient is charged to a surgeon, it is not enough to show that he has not treated his patient in that mode or has not used measures which in the opinion of others, though medical men, the case required; because such evidence tends to prove errors of judgment, for which the defendant is not responsible, as much as it goes to prove a want of reasonable skill and care for which he may be responsible. Alone it is not evidence of the latter, and therefore a party must go further and prove, by other evidence, that the defendant assumed the character and undertook to act as a physician without the education, knowledge, and skill which entitled him to act in that capacity.” In Carpenter _v._ Blake, upon the last appeal (75 N. Y., 12), it was said that the reasonable ordinary care and diligence which the law requires of physicians and surgeons is that which persons engaged in the same general line of practice have and exercise in like cases.[196] _Story’s Statement of the Rule._—Story in his work on Bailments, p. 433, with his usual felicitous method of statement says: “In all cases where skill is required it is to be understood that it means _ordinary_ skill in the business or employment which the bailee undertakes; for he is not presumed to undertake for extraordinary skill, which belongs to a few men only in his business or employment, or for extraordinary endowments or acquirements. Reasonable skill constitutes the measure of the engagement in regard to the thing undertaken.”
