But there is a reverse side to the picture. There is the man who has gone into the profession without aptitude for it, who has made it his, although positively incapable of properly learning it and exercising it. He may have acquired the right to use all the empty distinguishing letters attaching to it, and tack them after his name on all convenient occasions, inscribe them in staring characters on his very door-posts--M.D., M.R.C.S.--as many more as there may be to get; but, for all that, he is not capable of exercising the art. His whole career is one terrible mistake. He kills more patients than he cures; slaying them, drenching them to death, with that most pitiful and fatal of all weapons--ignorance. It may not be his fault, in one sense: he does his best: but he has embraced a calling for which nature did not fit him. He goes on in his career, it is true, and his poor patients suffer. More ignorant, of necessity, than he is--for in all that relates to the healing art, we are, take us as a whole, lamentably deficient--they can only blindly resign themselves to his hands, and when they find that there's no restored health for them, that they get worse rather than better, they blame the obstinacy of the malady, not the treatment. Upon his own mind, meanwhile, there rests an ever-perpetual sense of failure, irritating his temper, rendering his treatment experimental and uncertain. Some cannot see where the fault lies--have no conception that it is in their own incapacity. And if a man does see it, what then? He must go on and do his best; he must be a doctor always; it is his only means of living, and he is too old to take to another trade. Rely upon it there are more of these practitioners than the world suspects.
Such a man as the first was Dr. Davenal; such a man as the last was Mark Cray. But that Mark was so Dr. Davenal suspected not. Grave cases hitherto, during their short connection, had been treated by the doctor, and for ordinary ailments Mark did well enough. He could write a proper prescription when the liver was out of order, or bring a child through the measles; he could treat old ladies with fanciful ailments to the very acme of perfection. It is true Dr. Davenal had been once or twice rather surprised by downright wrong treatment on the part of Mark, but he had attributed it to inexperience.
