xl INTRODUCTORY REMARKS. 



Elias and Bushell in Mongolia ; Paderin at Karakorum ; 

 Prejevalsky in Tangut ; all have been tracking his steps 

 and throwing light, consciously or unconsciously, on his 

 Herodotean chapters. And yet what a vast area that he 

 has described from personal knowledge remains beyond 

 and outside of the explorations and narratives of these 

 meritorious travellers ! 



There remains but to add that the engagement to assist 

 Mr. Morgan in the production of this work was made, some 

 eighteen months ago, under circumstances which afforded 

 leisure for the task. The promise has had to be kept under 

 very different circumstances of place and occupation ; and 

 this must be the apology for some oversights, and perhaps 

 some repetitions, in the Notes and Introduction.'

^ Almost along with the revised proofs of these pages I have re- 

 ceived Mr. Markham's publication of the journeys of Bogle and 

 Manning ; not in time to benefit by it, unless by a few minor insertions 

 in the Supplementary Notes.
