The style of The Confidence-Man

Reading The Confidence-Man, I sometimes come across a rather tiresome sentence, though not as odd as many sentences written by Henry James. 
For example, from chapter VII: 

“Upon his hitherto moderate enough companion, this suggestion had an effect illustrative in a sort of that notion of Socrates, that the soul is a harmony; for as the sound of a flute, in any particular key, will, it is said, audibly affect the corresponding chord of any harp in good tune, within hearing, just so now did some string in him respond, and with animation.Which animation, by the way, might seem more or less out of character in the man in gray, considering his unsprightly manner when first introduced, had he not already, in certain after colloquies, given proof, in some degree, of the fact, that, with certain natures, a soberly continent air at times, so far from arguing emptiness of stuff, is good proof it is there, and plenty of it, because unwasted, and may be used the more effectively, too, when opportunity offers.” 

Or from chapter XII: 

“What made it yet more lamentable was, that the unfortunate man, thinking that, before the court, his wisest plan, as well as the most Christian besides, being, as he deemed, not at variance with the truth of the matter, would be to put forth the plea of the mental derangement of Goneril, which done, he could, with less of mortification to himself, and odium to her, reveal in self-defense those eccentricities which had led to his retirement from the joys of wedlock, had much ado in the end to prevent this charge of derangement from fatally recoiling upon himself—especially, when, among other things, he alleged her mysterious teachings.” 

At this point I don’t have much to say. The only thing is that the novel’s very different from Moby Dick. The exuberance, the joy and enthusiasm of Melville’s magnum opus are not to be found here. Nor is humour as we see in Moby Dick, though perhaps The Confidence-Man does have humour, a different kind. 
I’m noting, not really complaining. 
What do you think?
