Instead of a few great writers, the student is beset on all sides by writers of different sort and degree, from the light memorialist to the great historian; instead of two countries, two hemispheres are candidates for his attention; and history assumes a variety of garbs, many of which were strangers to her during the earlier period of her existence. To the careful study of many periods of history, not extending over any very wide portion of time, the labour of a tolerably long life would be inadequate. The unpublished Despatches of Cardinal Granvelle at Besançon, amount to sixty volumes. The archives of Venice (a mine, by the way, scarcely opened) fill a large apartment. For printed works it may be enough to mention the Benedictine editions and Munatoris Annals, historians of the dark and middle ages, relating to two countries only, and two periods. All history, therefore, however insatiable may be the intellectual _boulimia_ that devours him, can never be a proper object of curiosity to any man. It is natural enough that the first effect produced by this discovery on the mind of the youthful student should be surprise and mortification; nor is it before the conviction that his researches, to be valuable, must be limited, forces itself upon him, that he concentrates to some particular period, and perhaps to some exclusive object, the powers of his undivided attention. When he has thus put an end to his desultory enquiries, and selected the portion of history which it is his purpose to explore, his first object should be to avail himself of the information which other travellers in the same regions have been enabled to collect. Their mistakes will teach him caution; their wanderings will serve to keep him in the right path. Weak and feeble as he may be, compared with the first adventurers who have visited the mighty maze before him, yet he has not their difficulties to encounter, nor their perils to apprehend. The clue is in his hands which may lead him through the labyrinth in which it has been the lot of so many master-spirits to wander-- "And find no end, in boundless mazes lost." But it is time to hear Dr Arnold:--
