In a recent number of this Magazine, we took occasion to animadvert on the conceit and presumption of certain tourists who imagine themselves qualified by a flying visit to write their opinions concerning a country and people, thus doing grievous injustice to those they write about, and sadly misleading any credulous portion of the public which may be beguiled into reading and placing confidence in their lucubrations. It has been seen that no such reproach can be addressed to the author of the book we are now noticing, who has moreover performed his labour, which was no light one, in a conscientious and creditable manner, without prejudice, favour, or affection. We scarcely think he does full justice to Espartero, whom we must still persist in considering the most estimable and respectable of the Spanish public men of the day. He may not possess the glowing and fascinating eloquence of an Olozaga, nor the fierce energy of a Narvaez; but neither has he the versatile insincerity of the former, nor the unscrupulous and brutal recklessness of the latter. He has not, like Olozaga, according to the uncontradicted testimony of Roca de Togores in the Cortes, "broken faith with all parties;" nor did he ever, like Narvaez, cause his dragoons to charge inoffensive crowds, assembled by invitation of their rulers to celebrate saint-days or national festivals. Our author's general remarks on the state of Spain, of its people and prospects, are acute and sensible; and they also coincide in great measure with as much as has been said on those subjects by one or two recent and intelligent travellers in the Peninsula. In short, setting aside a slight occasional tendency to high colouring, more calculated, however, to amuse than mislead, the principal fault we have to find with the book is its title. After the deluges of Mysteries and Revelations that has been poured upon the shoulders of the reading public during the last two or three years, commencing with the rhapsodies of Sue and company, and continued through countless varieties by writers of every degree on both sides the Channel, we really cannot think that such a title as "Revelations" of any thing will tend to prepossess the public in favour of the work it designates. One frequently sees books of very small merit, or of none at all, ushered into the world under some highly enticing name, conveying the idea that the author has expended at his bantling's christening the whole of his diminutive modicum of talent. Here, however, is an example of the opposite mode of proceeding; a title that we must decidedly condemn, given to a book of much interest and utility--a book which, from its liveliness, and the amount of anecdote and light matter it contains, will be read by many who would shrink from the perusal of a mere dry statistical work.
