He was once applied to, to perform a serious operation on a tradesman's wife; the fee agreed upon was twenty guineas. He heard no more of the case for two months, at the end of which time he was called upon to perform it. In the course of his attendance he found out that the cause of the delay had been the difficulty under which the patient's husband had laboured to raise the money; and that they were worthy people, who had been unfortunate, and were by no means able to support the expense of such an affliction. 'I sent back to the husband nineteen guineas, and kept the twentieth,' said he, 'that they might not be hurt with an idea of too great an obligation. It somewhat more than paid me for the expense I had been at in the business.' He held the operative part of surgery in the lowest estimation. 'To perform an operation,' said he, 'is to mutilate the patient whom we are unable to cure; it should therefore be considered as an acknowledgment of the imperfection of our art.' Among other characteristics of genius, was his simplicity of character and singleness of mind. His works were announced as the works of _John Hunter_; and _John Hunter_ on a plain brass plate announced his residence. His honour and his pride made him look with contempt on the unworthy arts by which ignorant and greedy men advance their fortunes. He contemplated the hallowed duties of his art with the feelings of a philanthropist and a philosopher; and although surgery had been cultivated more than 2000 years, this single individual did more towards establishing it as a _science_, than all who preceded him."
