the art of flying, which was, as every body must acknowledge, in a condition quite disgraceful to civilized society. As he had made many a fire balloon, and had succeeded in some attempts at bringing down cats by _parachutes_, it was not very difficult to fly downward from moderate elevations. But, as he was reproached by my sister for never flying back again, which, how ever, was a far different thing, and not even attempted by the philosopher in "Rasselas" (for Revocare gradum et _superas_ evadere ad auras, Hic labor, hoc opus est), he refused, under such poor encouragement, to try his winged _parachutes_ any more, either "aloft or alow," till he had thoroughly studied Bishop Wilkins[12] on the art of translating right reverend gentlemen to the moon; and, in the mean time, he resumed his general lectures on physics. From these, however, he was speedily driven, or one might say shelled out, by a concerted assault of my sister's. He had been in the habit of lowering the pitch of his lectures with ostentatious condescension to the presumed level of our poor understandings. This superciliousness annoyed my sister; and, accordingly, with the help of two young female visitors, and my next younger brother--in subsequent times a little middy on board many a ship of H.M., and the most predestined rebel upon earth against all assumptions, small or great, of superiority--she arranged a mutiny, that had the unexpected effect of suddenly extinguishing the lectures forever. He had happened to say, what was no unusual thing with him, that he flattered himself he had made the point under discussion tolerably clear; "clear," he added, bowing round the half-circle of us, the audience, "to the meanest of capacities;" and then he repeated, sonorously, "clear to the most excruciatingly mean of capacities." Upon which a voice, a female one, but whose I had not time to distinguish, retorted: "No, you haven't; it's as dark as sin;" and then, without a moment's interval, a second voice exclaimed, "Dark as night;" then came my young brother's insurrectionary yell, "Dark as midnight;" then another female voice chimed in melodiously, "Dark as pitch;" and so the peal continued to come round like a catch, the whole being so well concerted, and the rolling fire so well sustained, that it was impossible to make head against it; while the abruptness of the interruption gave to it the protecting character of an oral "round robin," it being impossible to challenge any one in particular as the ring-leader. Burke's phrase of "the swinish multitude," applied to mobs, was then in every body's mouth; and, accordingly, after my brother had recovered from his first astonishment at this insurrection, he made us several sweeping bows that looked very much like tentative rehearsals of a sweeping _fusillade_, and then addressed us in a very brief speech, of which we could distinguish the words _pearls_ and _swinish multitude_,
