With respect to the arrangement of these pages, in order that there may be no interruption, I have divided the book into two parts; the first containing the description of my journey from Teheran to Samarcand and back, the second devoted to notices concerning the geography, statistics, politics, and social relations of Central Asia. I hope that both will prove of equal interest to the reader; for whilst on the one hand I pursued routes hitherto untrodden by any European, my notices relate to subjects hitherto scarcely, if at all, touched on by writers upon Central Asia. And now let me perform the more pleasing task of expressing my warm acknowledgments to all those whose kind reception of me when I arrived in London has been a great furtherance and encouragement to the publication of the following narrative. Before all let me mention the names of SIR JUSTIN and LADY SHEIL. In their house I found English open-heartedness associated with Oriental hospitality; their kindness will never be forgotten by me. In Central Asia I bestowed blessing for kindness received; here I have but words, they are sincere and come from the heart.
