PLATE 6. 



See Chapter VI. 



Hypothetical Map of the Geological Structure of China, based on Observations in the North and 

 in the Basin of the Yangtse Kiang, and on a Study of the Mineral Productions of the Umpire. 



The geographical basis of this map is taken from Arrowsmith's map, published in Blackiston's 

 " Five Months on the Upper Yangtse." 



I have altered the position of the Lower Yellow river on the map, to make it agree with its present 

 course.
