PROFESSOR AGASSIZ has discovered "a fish which builds a nest." Wonders are only just beginning. Other Professors, envious of AGASSIZ'S good fortune, will be stimulated to renewed study of the Animal Kingdom; and the result will be that at no distant day we shall see the great Zoological collections, here and in America, enriched by the addition of a glowworm which lives in a hive, a tortoise which hops from bough to bough, an oviparous rabbit, and a lobster whose diet consists exclusively of salad. The fable which deluded our childhood may yet be realised, and pigeon's milk take its place amongst the common articles of a free breakfast table. * * * * * NEW SCHOOL FOR NOBS. [Illustration: K]IND _Mr. Punch_, a happy change has come over the character of our Public Schools. The chief of them, I have been told, of what is called mediaeval foundation, were originally intended to educate the sons of poor gentlemen. But now, Sir, the purpose they have come to serve is just the reverse of that. A correspondent of the _Morning Post_, signing himself PAVIDUS--evidently a mean, shabby, needy sprig of gentility, afraid, as his signature means, if I am not misinformed, which, by the tenor of his letter, he plainly confesses himself to be, of having to fork out more than he is able--writes to complain, forsooth, of "the growing abuse of 'tips' and pocket-money allowance." This contemptible indigent fellow says:-- "It is within my knowledge that at one of the chief public schools--and I am told that the same rule holds good at the other schools of this class--a boy who does not bring back L5 each half is set down by 'the house' as a 'duffer' and as of 'no use.' In other words, he is under the cold shade of his fellow-boarders, and is subject to constant and galling humiliation." Very well. Let him be off, then. A first-class Public School is no place for him any more than a first-class carriage. Let the beggar who doesn't like it, leave it--go second or third class, and be taught the three R's under FORSTER'S Education Act. But now read what PAVIDUS has the insolence to say further:-- "It is not every lad that can bear lightly the gibes and jeers of the young cotton lords whose home ethics teach them to measure the quality of a gentleman by the amount of money he can spend. The result is inevitable. The 'soc' shop gives credit. A loan is soon and easily contracted, and the boy, smarting under the results of his comparative poverty, begins his career of debt and deceit in order to hold his own among his more pecunious fellows." MR. PAVIDUS, in his pride and poverty, seems very indignant at the idea of wealthy young cotton lords treating poor young pedigree lords with contempt. I dare say he is some poor nobleman's relation himself, the HONOURABLE PAVIDUS, perhaps, or RIGHT HONOURABLE PAVIDUS.
