_Mr. B._ But that, Louisa, is exactly what I do not wish you to do. I would greatly prefer that your information should be rather circumscribed, provided it were correct, than that you should have a slight smattering of many things, and a thorough knowledge of none. You may impose upon the illiterate by this superficial information; but the really wise will soon discover your ignorance, and despise you for affecting a degree of knowledge you do not possess. Besides which, a mere smattering of learning is very apt to fill the mind with self- conceit and vanity, faults from which the really well-informed are always free. My favourite poet, Pope, says:-- "A little knowledge is a dangerous thing; Drink deep, or taste not the Pierian spring. Here shallow draughts intoxicate the brain, But drinking largely sobers us again." Therefore, my dear, unless you intend to enter decidedly upon the study, I shall certainly beg your mother not to say any thing further on the subject. _Louisa_. Oh, then, I assure you, papa, I will enter decidedly upon it; as it seems to me as if it would be extremely entertaining. _Mr. B_. I think, my dear, you have formed your opinion somewhat prematurely, as you certainly, at present, know very little of the matter. This, however, with the young and ignorant, is no uncommon error. I hope your good opinion of the study, will continue when you are better acquainted with it. There are seven orders belonging to the first class, as your mother has already informed you; the names of which are, Primates, Bruta, Ferae, Glires, Picora, Beluae, and Cete. _Louisa_. Those words are harder than the classics. I doubt I shall find them more difficult to remember: however, I must write them down, and try my best. Please not to tell me any more at present, papa. I believe I shall succeed best, if I do not puzzle myself by attempting too much at a time. "I am quite of your opinion there," replied her father. _Louisa_. Natural history shall be one of my pleasures. I will not call it a lesson; but will study it when I am most in the fit for it. And will you be so kind as to help me, papa? "Willingly, my dear, provided your fit comes on when I am at liberty," replied Mr. Bernard. Louisa thanked her father, adding, "and now I must tell you, that I am quite satisfied with the account I have read of Servius Tullius. I perfectly understand now, who he is." _Ferdinand_. Louisa, before we begin our history, I wish to ask papa a question about those verses which he repeated a few minutes ago. There is one line, which I do not think I understand. Please to say them over once more, papa. _Mr. B._ "A little knowledge is a dangerous thing; Drink deep, or taste not the Pierian spring. Here shallow draughts intoxicate the brain, But drinking largely sobers us again."
