Quote #4
"And it is a remarkable example of the confusion into which the present age has fallen; of the obliteration of landmarks, the opening of floodgates, and the uprooting of distinctions," says Sir Leicester with stately gloom, "that I have been informed by Mr. Tulkinghorn that Mrs. Rouncewell's son has been invited to go into Parliament. [...] He is called, I believe--an--ironmaster." Sir Leicester says it slowly and with gravity and doubt, as not being sure but that he is called a lead-mistress or that the right word may be some other word expressive of some other relationship to some other metal. (28.23-27)
Sir Dedlock is floored by the idea that Rouncewell would be allowed into Parliament alongside him. Granted, they'd be in different houses: as a member of the aristocracy Dedlock is in the House of Lords, while as a commoner Rouncewell would be in the House of Commons. But still. Also, the euphemisms are great – "uprooting of distinctions" means "he should be kissing my boots." And finally we get a good sense of what Sir Dedlock values – birth – when he calls a clearly quite wealthy factory owner and iron magnate "Mrs. Rouncewell's son," a.k.a. someone born to be a servant.
Quote #5
"[Mr. Rouncewell] arrived this evening shortly before dinner and requested in a very becoming note"--Sir Leicester, with his habitual regard to truth, dwells upon it--"I am bound to say, in a very becoming and well-expressed note, the favour of a short interview with yourself and myself on the subject of this young girl." [...] Mr. Rouncewell is a little over fifty perhaps, of a good figure, like his mother, and has a clear voice, a broad forehead from which his dark hair has retired, and a shrewd though open face. He is a responsible-looking gentleman dressed in black, portly enough, but strong and active. Has a perfectly natural and easy air and is not in the least embarrassed by the great presence into which he comes. [...] Sir Leicester is content enough that the ironmaster should feel that there is no hurry there; there, in that ancient house, rooted in that quiet park, where the ivy and the moss have had time to mature, and the gnarled and warted elms and the umbrageous oaks stand deep in the fern and leaves of a hundred years; and where the sun-dial on the terrace has dumbly recorded for centuries that time which was as much the property of every Dedlock--while he lasted-- as the house and lands. Sir Leicester sits down in an easy-chair, opposing his repose and that of Chesney Wold to the restless flights of ironmasters. (28.30-38)
The text slows down here nicely to imitate the gradual, calm, long flow of Sir Dedlock's thoughts as they wander around the estate of Chesney Wold. This is in contrast with Rouncewell, who is all action and fast movement.
Quote #6
Out of the court, and a long way out of it, there is considerable excitement too, for men of science and philosophy come to look, and carriages set down doctors at the corner who arrive with the same intent, and there is more learned talk about inflammable gases and phosphuretted hydrogen than the court has ever imagined. Some of these authorities (of course the wisest) hold with indignation that the deceased had no business to die in the alleged manner; and being reminded by other authorities of a certain inquiry into the evidence for such deaths reprinted in the sixth volume of the Philosophical Transactions; and also of a book not quite unknown on English medical jurisprudence; and likewise of the Italian case of the Countess Cornelia Baudi as set forth in detail by one Bianchini, prebendary of Verona, who wrote a scholarly work or so and was occasionally heard of in his time as having gleams of reason in him; and also of the testimony of Messrs. Fodere and Mere, two pestilent Frenchmen who WOULD investigate the subject; and further, of the corroborative testimony of Monsieur Le Cat, a rather celebrated French surgeon once upon a time, who had the unpoliteness to live in a house where such a case occurred and even to write an account of it--still they regard the late Mr. Krook's obstinacy in going out of the world by any such by-way as wholly unjustifiable and personally offensive. (23.91-92)
It's not often that novelists need to make scholarly citations in their novels, but here that's just what we've got. All those names and books and bits of research Dickens cites are real-life people who claim that there's such a thing as human spontaneous combustion. Krook had combusted in the previously published part of the novel, and that nonsense was so viciously and immediately attacked by readers that the next chapter tried to restore Dickens's own reputation.
