The No. for April, 1820, mentions, 
* A new Geological map of England and Wales, with 
the inland navigation, &c. &c.: By Wm. Smith, Engineer, 
on one large sheet, neatly coloured and shaded—Cary, St. 
James-st. price 14s.” 
_  Smith’s Geological Atlas, No. 3, is published by Cary. 
This work exhibits on separate maps, the Geology of the

found.” He returned last year to Paris, bringing a vast
