Explanation to the above. Prof. Dr. Orth, Berlin* 



The learned English physician, Dr. Lister, in the year 1683, proposed to the 

 Royal Society of London, to prepare a map which should represent English 

 soils and minerals, their distribution to be shown by special colours, &c. The 

 above maps represent a new mode of geological " ehartography," and exhibit 

 the soil in its geographical position, and with its economical uses in a more 

 precise manner than has hitherto been possible.
