London, Richard Bentley, 1853 (second edition, with additions and corrections)/ 1852.
Octavo, xvi, 455 pages with a chromolithographic frontispiece, a plate and a narrow folding map.
Contemporary full calf, the spine gilt-decorated in compartments, with a contrasting title-label; all edges marbled; leather lightly marked and scuffed, and a little rubbed and bumped at the extremities; spine rubbed, affecting much of the gilt decoration; a few small light tidemarks near the edges of the frontispiece (as a result of the marbling); text paper uniformly lightly tanned; an excellent copy with the 1859 prize plate of the Institute of Public Education, London, on the pastedown.
Essentially the narrative of this important expedition, reprinting letters 'almost in their original form as they were written, sometimes as a report direct to his Majesty the King, sometimes to his Excellency ... Eichhorn, or to other high patrons and honoured men, as A. Von Humboldt, Bunsen, Von Oflers, Ehrenberg, and sometimes to my father'. The letters give '(without taking the purely scientific labours into account) ... a picture of the external events of the expedition, of the relative operations of its members, of the obstacles, and the favourable circumstances of the journey, the condition of the countries through which it passed, and their effect upon the actual design of the undertaking; finally to offer a few observations on the remarkable monuments of that most historical of all countries' (from the author's preface).
