Messrs. Longman have this month given a judicious and agreeable variety to _The Traveller's Library_ by substituting for one of Mr. Macaulay's brilliant political biographies a volume of travels; and in selecting Mr. Laing's _Journal of a Residence in Norway during the Years 1834, 1835, and 1836_ (which is completed in Two Parts), they have shown excellent discretion. For, as Mr. Laing well observes, "few readers of the historical events of the middle ages rise from the perusal without a wish to visit the country from which issued in the tenth century the men who conquered the fairest portion of Europe." But as, even in these locomotive times, all cannot travel, but many are destined to be not only home-keeping youths but "house-keeping men" also, all such have reason to be grateful to pleasant intelligent travellers like Mr. Laing for giving them the results of their travels in so pleasant a form; and especially grateful to Messrs. Longman for giving it to them at a price which places it within the reach of every one. _The Literature of the Rail; republished, by permission, from_ The Times _of Saturday, August 9th, 1851, with a Preface_, has just been issued by Mr. Murray, in the shape of a sixpenny pamphlet. This will be a gratifying announcement to those who read and wished to preserve this startling article on a subject which must come home to every thinking mind,--to every one who has witnessed, as we have done, the worse than worthless, the positively mischievous trash in the shape of literature too often to be found on the bookstalls of railway stations. But there is hope. The success which has attended the wholesome change effected on the North-Western line is sure to lead to an extension of the better system; and we are glad to see that the endeavours making by Messrs. Longman to supply, by means of _The Traveller's Library_, the growing want for _good and cheap_ books, are to be seconded by Mr. Murray, who announces a Series under the title of _Literature for the Rail_, and the opening number of which is to be _A Popular Account of Mr. Layard's Discoveries at Nineveh, abridged by himself from the larger Work, and illustrated by numerous Woodcuts_. We are glad to see that the Trustees of the British Museum have printed a _List of the Autograph Letters, Original Charters, Great Seals, and Manuscripts, exhibited to the Public in the Department of Manuscripts_. The selection does great credit to the intelligent Keeper of the Manuscripts; and the exhibition of these treasures will, we trust, do something more than merely gratify the curiosity of the thousands of the people who have visited them, namely, encourage their representatives in Parliament to a more liberal vote for this important department of the Museum. Valuable manuscripts are not always in the market; when they are, the country should never lose them through a mistaken parsimony.
