 I/. London, 1833. 



" In. the summer of 1831, I made a geological excursion to 

 the volcanic district of the Eifel ; and, on my return, I 

 determined to extend my work to three volumes, the second 

 of which appeared in January, 1832. The last (the third) 

 volume has been delayed till now by many interruptions ; 

 among which I may mention a tour, in the summer of 1832, 

 up the valley of the Rhine, when I examined the loess 

 (vol. iii. p. 151.), and a visit, on my way home, through Swit- 

 zerland, to the Valorsine ; where I had an opportunity of 

 verifying the observations of M. Necker on the granite veins 

 and altered stratified rocks of that district." (Preface, page 

 xviii.)
