Bar and Bishop had both been bystanders during this short dialogue, and as Mr Merdle was swept away by the crowd, they made their remarks upon it to the Physician. Bar said, there was a certain point of mental strain beyond which no man could go; that the point varied with various textures of brain and peculiarities of constitution, as he had had occasion to notice in several of his learned brothers; but the point of endurance passed by a line's breadth, depression and dyspepsia ensued. Not to intrude on the sacred mysteries of medicine, he took it, now (with the jury droop and persuasive eye-glass), that this was Merdle's case? Bishop said that when he was a young man, and had fallen for a brief space into the habit of writing sermons on Saturdays, a habit which all young sons of the church should sedulously avoid, he had frequently been sensible of a depression, arising as he supposed from an over-taxed intellect, upon which the yolk of a new-laid egg, beaten up by the good woman in whose house he at that time lodged, with a glass of sound sherry, nutmeg, and powdered sugar acted like a charm. Without presuming to offer so simple a remedy to the consideration of so profound a professor of the great healing art, he would venture to inquire whether the strain, being by way of intricate calculations, the spirits might not (humanly speaking) be restored to their tone by a gentle and yet generous stimulant?

'Yes,' said the physician, 'yes, you are both right. But I may as well tell you that I can find nothing the matter with Mr Merdle. He has the constitution of a rhinoceros, the digestion of an ostrich, and the concentration of an oyster. As to nerves, Mr Merdle is of a cool temperament, and not a sensitive man: is about as invulnerable, I should say, as Achilles. How such a man should suppose himself unwell without reason, you may think strange. But I have found nothing the matter with him. He may have some deep-seated recondite complaint. I can't say. I only say, that at present I have not found it out.'

There was no shadow of Mr Merdle's complaint on the bosom now displaying precious stones in rivalry with many similar superb jewel-stands; there was no shadow of Mr Merdle's complaint on young Sparkler hovering about the rooms, monomaniacally seeking any sufficiently ineligible young lady with no nonsense about her; there was no shadow of Mr Merdle's complaint on the Barnacles and Stiltstalkings, of whom whole colonies were present; or on any of the company. Even on himself, its shadow was faint enough as he moved about among the throng, receiving homage.

Mr Merdle's complaint. Society and he had so much to do with one another in all things else, that it is hard to imagine his complaint, if he had one, being solely his own affair. Had he that deep-seated recondite complaint, and did any doctor find it out? Patience, in the meantime, the shadow of the Marshalsea wall was a real darkening influence, and could be seen on the Dorrit Family at any stage of the sun's course.
