of time and this very industry and precision procures them more true leisure than indolence can boast of." In referring to the relation of practitioner to patient, he spoke on a subject which has been much discussed in recent years without altering the principle originally laid down in the oath of Hippocrates:--"Whatever," said Simpson, "is communicated to you as a matter of professional confidence, must ever remain buried within your own breasts in all the silence and secrecy of the grave." He concluded his address with well-judged remarks on the relation of the physician to his professional brethren, counselling his hearers to observe the Golden Rule, and, moreover, "if it be possible, as much as lieth in you, live peaceably with all men; never allow the darker part of your nature to persuade you to the attempt of over-taking him who has distanced you in the race of life by any unjust efforts to lame the character, and thus diminish the speed, of your adversary. And if such attempts are made upon you by others, have no dread of them--if you are armed strong in honesty, if you have pursued a line of irreproachable truth and unbending rectitude of conduct. 'Be thou as pure as snow thou shalt not escape calumny.'... Your future career is a matter of your own selection, and will be regulated by the conduct which you choose to follow. That career may be one of happiness or self-regret, one of honour or of obscurity, one of wealth or of poverty. The one or other result is not a matter of _chance_, but a matter of choice on your part. Your diligence and industry for the next few years will almost inevitably secure for you the one; your apathy and indolence will almost inevitably entail upon you the other. May God, in His infinite goodness, enable you to select the wiser and the better path." In this address, as in that previously quoted, we hear him exhorting his young listeners to a line of conduct which we know to have been broadly his own in practice as well as in ideal. During these early years as professor, Simpson had to ward off many ill-disposed adversaries, and he met their attack with the determination and powerful preparedness that characterised his attitude in later years, when he experienced the hostility so constantly opposed to genuine reformers, and men who have lived ahead of their times. He sometimes regarded these encounters regretfully himself; but none the less remembered to "Bear't that the opposed may beware."
