Necessarily there are many cases to which this rule does not seem to apply, those of contagious sickness, for instance, or those of surgery, resulting from accident.  And yet even there it does apply, for the condition of the mind may predispose to infection, and to recovery or collapse in the instance of the sufferer from injuries.  But these questions of predisposition and consequence are too great to argue here, though even the most rule-of-thumb village practitioner, with a black draught in one hand and a pot of ointment in the other, will agree that they admit of a wide application.

At least it is to these primary principles over and above my technical skill that I attribute my success while I was successful.  That at any rate was undoubted.  Day by day my practice grew, to such an extent indeed, that on making up my books at the end of the second year, I found that during the preceding twelve months I had taken over 900 pounds in fees and was owed about 300 pounds more.  Most of this balance, however, I wrote off as a bad debt, since I made it a custom never to refuse a patient merely because he might not be able to pay me.  I charged large fees, for a doctor gains nothing by being cheap, but if I thought it inexpedient I did not attempt to collect them.

After this matter of the inquest on Major Selby the relations between Sir John Bell and myself were very strained—­in fact, for a while he refused to meet me in consultation.  When this happened, without attempting to criticise his action, I always insisted upon retiring from the case, saying that it was not for me, a young man, to stand in the path of one of so great experience and reputation.  As might be expected this moderation resulted in my triumph, for the time came when Sir John thought it wise to waive his objections and to recognise me professionally.  Then I knew that I had won the day, for in that equal field I was his master.  Never once that I can remember did he venture to reverse or even to cavil at my treatment, at any rate in my presence, though doubtless he criticised it freely elsewhere.

And so I flourished, and as I waxed he waned, until, calculating my chances with my wife, I was able to prophesy that if no accident or ill-chance occurred to stop me, within another three years I should be the leading practitioner in Dunchester, while Sir John Bell would occupy the second place.

But I had reckoned without his malice, for, although I knew this to be inveterate, I had underrated its probable effects, and in due course the ill-chance happened.  It came about in this wise.

When we had been married something over two years my wife found herself expecting to become a mother.  As the event drew near she expressed great anxiety that I should attend upon her.  To this, however, I objected strenuously—­first, because I cannot bear to see any one to whom I am attached suffer pain, and, secondly, because I knew that my affection and personal anxiety would certainly unnerve me.  Except in cases of the utmost necessity no man, in my opinion, should doctor himself or his family.  Whilst I was wondering how to arrange matters I chanced to meet Sir John Bell in consultation.  After our business was over, developing an unusual geniality of manner, he proposed to walk a little way with me.
