In this, Dr.Wilkinson was giving audience to a gentleman who had brought back his little boy a few minutes before Louis arrived.

Having some private business to transact, the child was sent to the school-room, and then Mr.Percy entered into a discussion respecting the capabilities of his son, and many other particulars, which, however interesting to himself, would fail of being so to us.
At length these topics were exhausted, and it seemed nearly decided how much was to be done or discontinued in Master Percy's education.
Mr.Percy paused to consider if any thing were left unsaid.
"Oh! by the by, Dr.Wilkinson," he said, letting fall the pencil with which he had been tapping the table during his cogitations, "you have one of Sir George Vernon's grandsons with you, I believe ?" "Two of them," replied the doctor.
"Ah! indeed, I mean young Mortimer, son of Mr.Mortimer of Dashwood." "I have his eldest son, and am expecting another to-day." "Then it was your expected pupil that I saw this morning," said Mr.Percy.
"May I ask where ?" said the doctor.
"At the White Lion.

He came down by the London coach.

I saw his trunk, in the first place, addressed to you, and supposed him to be the young gentleman who attained to some rather undesirable notoriety last year." "How so ?" asked the doctor.
"Oh! he very ungenerously and artfully endeavored to retain for himself the honor of writing a clever little essay, really the work of his brother, and actually obtained a prize from his grandfather for it." "How came that about ?" asked Dr.Wilkinson.
"Oh! there was some mistake in the first instance, I believe, and the mean little fellow took advantage of it." Mr.Percy then gave a detailed account of Louis' birthday at Heronhurst, and concluded by saying-- "I was not present, but I heard it from a spectator; I should be afraid that you will not have a little trouble with such a character." "It is extraordinary," said the doctor; "his brother is the most frank, candid fellow possible." "I hear he is a nice boy," said Mr.Percy.

"There is frequently great dissimilarity among members of the same family; but of course, this goes no further.
