Trieste, Jan. 31, 1875.

My Dear Sir George,

Our paths in life have been separated by a long interval. Whilst inclination led you to explore and to’survey the wild wastes of the North, the Arctic shores and the Polar seas, with all their hardships and horrors; my lot was cast in the torrid regions of Sind and Arabia; in the luxuriant deserts of Africa, and in the gorgeous tropical forests of the Brazil. But the true traveller can always appreciate the record of another’s experience, and perhaps the force of contrast makes him most enjoy the adventures differing the most from his own. To whom, then, more appropriately than to yourself, a discoverer of no ordinary note, a recorder of explorations, and, finally, an earnest labourer in the cause of geography, can I inscribe this plain, unvarnished tale of a soldier-traveller? Kindly accept the trifle as a token of the warmest esteem, an earnest of my thankfulness for the interest ever shown by you in forwarding my plans and projects of adventure; and, in the heartfelt hope that Allah may prolong your days, permit me to subscribe myself,

Your sincere admirer and grateful friend, RICHARD F. BURTON.

Admiral Sir George Back, D.C.L., F.R.S., Vice–Pres. R.G.S., &c.
