Mr. Whymper has written the history of the conquest of the Matterhorn _quorum pars magna fuit_, and his book is a worthy record of a great achievement. Making a not unreasonable allowance for the difficulties of a writer who is the hero of his own story, and for the necessary conflict between his modesty and his fidelity, and with the single remark that the former is not unduly sacrificed to the latter, we may commend to our readers a most interesting and exciting narrative, written with lucidity and skill, terseness and pertinence, and illustrated by Mr. Whymper himself, whose pencil, he tells us, has been employed upon the work for the greater part of the last six years. The illustrations are very numerous and effective, and, generally speaking, all of a high artistic quality; with the letterpress, they make a really sumptuous Alpine volume. From the very nature of some of the subjects, some little has been supplied by the imagination. For instance, the flying fragments in the 'Cannonade on the Matterhorn' are not all of them in the line of any conceivable projectile force; and certainly the 'Fall of Reynaud,' as represented p. 229, could have had, for him, but one issue, and that not of a kind to produce 'roars of laughter' from his companions. Had Mr. Whymper fallen, as pictorially represented p. 120, he would never have written his book save, indeed, with the assistance of Mr. Home. His survival is, indeed, a miracle. He fell, he tells us, 200 feet 'in seven or eight bounds--ten feet more would have taken me, in one gigantic leap of 800 feet, on to the glacier below.' He describes his sensations as by no means unpleasant, and thinks that death by a fall from a great height is painless. Hardly, again, should we have fancied the suicidal position of Croz cutting away the cornice on the summit of the Monning Pass. Photographs, had such been possible, would, we imagine, have presented some striking divergencies from these imaginary positions. But, making allowance for pictorial effect in these two or three instances, the illustrations appear to have been done with great care, as well as with great spirit. Some excellent maps are also furnished; two are transferred from the plates of the Dufour Map; two, a map of the chain of Mont Blanc, based upon the Government maps of France and Switzerland, and the survey of Mr. Reilly, and a map of the Matterhorn and its glaciers, being an enlargement, with corrections, from the Dufour Map, are original. The fifth is a general route map.
