a system of Prince's nails!

I give 'em away to the young ladies. They put 'em in albums, I believe. Ha! ha! ha! Upon my life, "the whole social system" (as the men call it when they make speeches in Parliament) is a system of Prince's nails!' said this least of women, trying to fold her short arms, and nodding her large head.
Steerforth laughed heartily, and I laughed too. Miss Mowcher continuing all the time to shake her head (which was very much on one side), and to look into the air with one eye, and to wink with the other. This was an invocation to Steerforth to place himself under her hands; who, accordingly, sat himself down, with his back to the table, and his laughing face towards me, and submitted his head to her inspection, evidently for no other purpose than our entertainment. To see Miss Mowcher standing over him, looking at his rich profusion of brown hair through a large round magnifying glass, which she took out of her pocket, was a most amazing spectacle.
'You're a pretty fellow!' said Miss Mowcher, after a brief inspection. 'You'd be as bald as a friar on the top of your head in twelve months, but for me. just half a minute, my young friend, and we'll give you a polishing that shall keep your curls on for the next ten years!'
With this, she tilted some of the contents of the little bottle on to one of the little bits of flannel, and, again imparting some of the virtues of that preparation to one of the little brushes, began rubbing and scraping away with both on the crown of Steerforth's head in the busiest manner I ever witnessed, talking all the time. Put this and that together, my tender pupil,' returned the wary Mowcher, touching her nose, 'work it by the rule of Secrets in all trades, and the product will give you the desired result. I say I do a little in that way myself. One Dowager, SHE calls it lip-salve. Another, SHE calls it gloves. Another, SHE calls it tucker-edging. Another, SHE calls it a fan. I call it whatever THEY call it. I supply it for 'em, but we keep up the trick so, to one another, and make believe with such a face, that they'd as soon think of laying it on, before a whole drawing-room, as before me. I never did in my days behold anything like Mowcher as she stood upon the dining table, intensely enjoying this refreshment, rubbing busily at Steerforth's head, and winking at me over it.The first exclamation sounded like a question put to both of us, and the second like a question put to Steerforth only. She seemed to have found no answer to either, but continued to rub, with her head on one side and her eye turned up, as if she were looking for an answer in the air and were confident of its appearing presently. Her tone and look implied something that was not agreeable to me in connexion with the subject. So I said, in a graver manner than any of us had yet assumed: 'She is as virtuous as she is pretty. She is engaged to be married to a most worthy and deserving man in her own station of life. I esteem her for her good sense, as much as I admire her for her good looks.
