The medical man has ofttimes to sail between Scylla and Charybdis. While, on the one hand, he is bound to consult the attainable literature in his profession, and to diligently gather in, for every case he undertakes to treat, the experience of his confreres—for in determining what is negligence, the improvements that are constantly taking place are always considered—at the same time he must not try new modes or methods too readily, lest a Judge say of him, as one said in a surgery case, “It appears from the evidence of the surgeons that it was improper to disunite the callus without consent. This is the usage and law of surgeons. Then it was ignorance and unskilfulness, in that very particular, to do contrary to the rule of the profession what no surgeon ought to have done. For anything that appears to the court, this was the first experiment made with this new instrument; and, if it was, it was a rash action, and he who acts rashly acts ignorantly; and although the defendants (a surgeon and an apothecary), in general, may be as skilful in their respective professions as any two gentlemen in England, yet the court cannot help saying that, in this particular case, they acted ignorantly and unskilfully, contrary to the known rule and usage of surgeons;” (and they had to pay the plaintiff £500 for the damage to his leg) [174]. Success is the only thing that justifies an innovation either in politics or physic. When it is proved that the physician has omitted altogether the established mode of treatment, and has adopted one that has proved to be injurious, evidence of skill, or of reputation for skill, is wholly immaterial, except to show (what the law presumes) that he possesses the ordinary |72| degree of skill of persons engaged in the same profession. In such a case, it is of no consequence how much skill he may have; he has demonstrated a want of it in the treatment of the particular case.
