He was capable of receiving correction.

Her father told her he was indebted to Mr. Tuckham past payment in coin,
for services rendered by him on a trying occasion among the miners in
Wales during the first spring month. 'I dare say he can speak
effectively to miners,' Cecilia said, outvying the contemptuous young man
in superciliousness, but with effort and not with satisfaction.

She left London in July, two days before her father could be induced to
return to Mount Laurels. Feverish, and strangely subject to caprices
now, she chose the longer way round by Sussex, and alighted at the
station near Steynham to call on Mrs. Culling, whom she knew to be at the
Hall, preparing it for Mr. Romfrey's occupation. In imitation of her
father she was Rosamund's fast friend, though she had never quite
realized her position, and did not thoroughly understand her. Would it
not please her father to hear that she had chosen the tedious route for
the purpose of visiting this lady, whose champion he was?

So she went to Steynham, and for hours she heard talk of no one, of
nothing, but her friend Nevil. Cecilia was on her guard against
Rosamund's defence of his conduct in France. The declaration that there
had been no misbehaviour at all could not be accepted; but the news of
Mr. Romfrey's having installed Nevil in Holdesbury to manage that
property, and of his having mooted to her father the question of an
alliance between her and Nevil, was wonderful. Rosamund could not say
what answer her father had made: hardly favourable, Cecilia supposed,
since he had not spoken of the circumstance to her. But Mr. Romfrey's
influence with him would certainly be powerful.
