My reading has been lamentably desultory and immethodical. Odd, out of the way, old English plays, and treatises, have supplied me with most of my notions, and ways of feeling. In every thing that relates to _science_, I am a whole Encyclopædia behind the rest of the world. I should have scarcely cut a figure among the franklins, or country gentlemen, in king John's days. I know less geography than a school-boy of six weeks' standing. To me a map of old Ortelius is as authentic as Arrowsmith. I do not know whereabout Africa merges into Asia; whether Ethiopia lie in one or other of those great divisions; nor can form the remotest conjecture of the position of New South Wales, or Van Diemen's Land. Yet do I hold a correspondence with a very dear friend in the first-named of these two Terræ Incognitæ. I have no astronomy. I do not know where to look for the Bear, or Charles's Wain; the place of any star; or the name of any of them at sight. I guess at Venus only by her brightness--and if the sun on some portentous morn were to make his first appearance in the West, I verily believe, that, while all the world were gasping in apprehension about me, I alone should stand unterrified, from sheer incuriosity and want of observation. Of history and chronology I possess some vague points, such as one cannot help picking up in the course of miscellaneous study; but I never deliberately sat down to a chronicle, even of my own country. I have most dim apprehensions of the four great monarchies; and sometimes the Assyrian, sometimes the Persian, floats as _first_ in my fancy. I make the widest conjectures concerning Egypt, and her shepherd kings. My friend _M._, with great painstaking, got me to think I understood the first proposition in Euclid, but gave me over in despair at the second. I am entirely unacquainted with the modern languages; and, like a better man than myself, have "small Latin and less Greek." I am a stranger to the shapes and texture of the commonest trees, herbs, flowers--not from the circumstance of my being town-born--for I should have brought the same inobservant spirit into the world with me, had I first seen it in "on Devon's leafy shores,"--and am no less at a loss among purely town-objects, tools, engines, mechanic processes.--Not that I affect ignorance--but my head has not many mansions, nor spacious; and I have been obliged to fill it with such cabinet curiosities as it can hold without aching. I sometimes wonder, how I have passed my probation with so little discredit in the world, as I have done, upon so meagre a stock. But the fact is, a man may do very well with a very little knowledge, and scarce be found out, in mixed company; every body is so much more ready to produce his own, than to call for a display of your acquisitions. But in a _tête-à-tête_ there is no shuffling. The truth will out. There is nothing which I dread so much, as the being left alone for a quarter of an hour with a sensible, well-informed man,
