Now, love was Miss Amelia Sedley's last tutoress, and it was amazing what progress our young lady made under that popular teacher. In the course of fifteen or eighteen months' daily and constant attention to this eminent finishing governess, what a deal of secrets Amelia learned, which Miss Wirt and the black-eyed young ladies over the way, which old Miss Pinkerton of Chiswick herself, had no cognizance of! As, indeed, how should any of those prim and reputable virgins? With Misses P. and W. the tender passion is out of the question: I would not dare to breathe such an idea regarding them. Miss Maria Osborne, it is true, was "attached" to Mr. Frederick Augustus Bullock, of the firm of Hulker, Bullock & Bullock; but hers was a most respectable attachment, and she would have taken Bullock Senior just the same, her mind being fixed--as that of a well-bred young woman should be--upon a house in Park Lane, a country house at Wimbledon, a handsome chariot, and two prodigious tall horses and footmen, and a fourth of the annual profits of the eminent firm of Hulker & Bullock, all of which advantages were represented in the person of Frederick Augustus. [...] Miss Maria, I say, would have assumed the spotless wreath, and stepped into the travelling carriage by the side of gouty, old, bald-headed, bottle-nosed Bullock Senior; and devoted her beautiful existence to his happiness with perfect modesty--only the old gentleman was married already; so she bestowed her young affections on the junior partner. [...] This was not the sort of love that finished Amelia's education; and in the course of a year turned a good young girl into a good young woman--to be a good wife presently, when the happy time should come. (12.19-20)
If all marriages were arranged by parents, then young women would be expected to just take anyone who's a good business proposition. This is illustrated nicely by Maria here, who doesn't really care which Bullock she ends up married to; she's marrying the money, not the person. This was a time when the idea of marriage as a purely financial and legal institution was starting to come into conflict with the notion of marriage as a love-based union between companions.
