Had he been more careful of pounds, shillings, and pence, he would have been more attentive to the details of practice. To Simpson, provided he had sufficient money for all his wants--and his wants were wide, for they included those of many others--pecuniary and business matters were of secondary consideration. In his student days he had lived carefully, accounting, as has been seen, for every trivial expenditure to those to whom he was indebted. But now he was free from the harassing necessity of exercising rigid economy, he cast aside the drudgery of business methods and disdained commercial considerations. He certainly received some very large fees, but the curious mixture of human beings who crowded his waiting-rooms were treated all alike whether they paid princely fees or no fee at all; lots were drawn daily for precedence, and they entered his presence according as they drew. His valet seems to have attained considerable skill in estimating the probable remunerative value of a roomful of waiting patients, and would grumble at night if on emptying the professor's pockets, as was his duty, the result fell short of his calculated anticipations. The man did not approve of the master's habit of giving gratuitous service. There were many who were never asked for a fee, and many others whose proffered guineas were refused. Simpson would not ask for money from those to whom he thought it was a struggle to pay him; the magnitude of his profit-yielding practice rendered this form of charity possible for him; from the really poor he always refused remuneration. His house was filled with all sorts of presents from patients, grateful for benefit conferred, grateful for generosity and consideration. He was also a free giver, and besides supporting orthodox charities made many gifts of goodly sums to persons who appeared to him to be in want, or who succeeded in impressing on him their need for help. He was imposed upon often enough; not seldom by pseudo-scientists full of some great discovery which a little more capital might enable them to complete. Once he corresponded with an enthusiast of this description who confessed that he had been breakfasting on a waistcoat, dining on a shirt, and supping on a pair of tough old leather boots, with the object of finding a solid substance, which combined with lead or tin would form gold--nothing more or less than the time-honoured philosopher's stone! To such a man Simpson gave freely not only once. To young students entering upon professional life with no other capital than their newly acquired qualifications to practice, he was ever generous. The Scots Universities sent forth many such youths, sturdy and independent, and with feelings that would be easily wounded by any attempt to patronise. But his gentleness, and the sympathy born of his own early experiences and shining in his eyes, made help from him something to be proud of.
