Politics, since the year 1848, have engrossed so unwonted a share of the attention of the reading world, that there can be no doubt that, in more than one European country, books of great literary and scientific interest have been withheld from publication until more tranquil days should give them a better chance of the welcome they merit. Such has avowedly been the case with Dr Wagner’s latest work, the fourth and most important of a series suggested to him by several years of Oriental travel and study. It was, if we rightly remember, in the second book of this series, relating to Armenia,[2] that he announced his intention of reserving for a final work the more important results of his rambles and observations. Previously to the Armenian volume he had published his account of Caucasus and the Cossacks,[3] to the general reader more interesting than any of its successors. Third in order of appearance came the Journey to Colchis;[4] and now, believing that his countrymen’s taste for books of foreign travel and adventure is reviving, he puts forth two copious volumes, containing all that he has to say, and that he has not previously published, concerning his Eastern journeyings and residence. Dr Wagner is one of the most experienced, indefatigable, and, as we believe, one of the most trustworthy and impartial of foreign literary travellers. On a former occasion we explained how his strong natural bent for travel and scientific research had overcome many and great obstacles, and had conducted him not only through various European countries, but with a French army to Constantina, and afterwards over a great part of Western Asia. His present book is comprehensive and somewhat desultory in its character. It details the author’s residence in the Alpine region of Turkish Armenia, his travels in Persia, and his adventurous visits to certain independent tribes of Kourds, whose country is immediately adjacent to that interesting but unsafe district of Kourdistan, where Schulze, the German antiquarian, and the Englishman Browne (the discoverer of Darfour) met a bloody death, and rest in solitary graves. Dr Wagner is sanguine that, now that the revolutionary fever has abated, many will gladly quit the study of newspapers, and the contemplation of Europe’s misty future, to follow him into distant lands, rarely trodden by European foot, and some of which have hitherto been undescribed “by any German who has actually visited them.” As the most novel portions of his book, he indicates his visits to the mountain district south of Erzroum, and his excursions east, south, and west of the great salt lake of Urumiah, the Dead Sea of Persia. A keen politician, and this book being, as we have already observed, a sort of omnium-gatherum of his Eastern experiences, political, scientific, and miscellaneous, he devotes his first chapter to what he terms “a dispassionate appreciation of Prince Metternich’s Oriental policy,”
