"Of the works already published, and professing to treat of this gigantic undertaking in its national, social, scientific, and artistic light, we have not met with one so completely pervaded by a spirit of universality as this book of Mr. Berlyn's. In matters of detail and relation his narrative is explicit and lucid; where he has touched on the history of an art or a manufacture he is correct in his data; and in tracing the Exhibition to its true source he has displayed a highly philosophical insight into the spirit of the age. Within the pages of his book will be found a faithful record of the most important meetings of the Royal Commissioners, as well as those convened by the corporations of cities, by societies, or by private individuals, for the furtherance of the great work in hand. To these is appended a verbatim report of the speeches delivered at these meetings by the distinguished men who were invited to preside over them; and the enlightened, liberal, and hopeful spirit which pervades their addresses forms a cheerful contrast to the ominous predictions of certain political and theological fanatics. After a full discussion of what may be termed the _business_ portion of the subject, Mr. Berlyn closes his excellent little book with a brief but eloquent and comprehensive consideration of the beneficial results which are likely to accrue from this great national undertaking, not only to ourselves but mankind in general. The entire absence of partiality or prejudice throughout the book, and the very interesting information contained in it for all matters directly or indirectly connected with the Exhibition, induce us to recommend the author to publish editions of it in the French and German languages. By this means he would be conferring a boon on our country's guests." LADY'S NEWSPAPER. "Mr. Peter Berlyn has produced a well arranged, clear, and concise hand book to this wonder of the world, in which he traces its origin, progress, and prospects, in a pleasing and interesting manner. This must have been a most difficult task, as the materials out of which he has formed his narrative are so widely scattered that it requires some one who perfectly and profoundly understands the subject (as we are convinced Mr. Berlyn does) to collect and arrange them in so satisfactory a manner. The ladies also will hail this work with pleasure, because, though containing every information on the subject, it is at the same time light, interesting, and infinitely superior to the dry and prosy style usually adopted in similar works. It is tastefully illustrated, has an elegant fancy binding, and forms a guide-book either for the library or the pocket." NOTES AND QUERIES. "A volume carefully compiled from authentic sources of information upon the several points set forth in its ample title page." GARDENER AND FARMERS' JOURNAL.
