Introduction. 



In several papers communicated to this Society, Mr. Strickland has de- 

 scribed the geology of some of the portions of Asia Minor, through which we 

 travelled together in the early part of 1836. When circumstances compelled 

 that gentleman to return to England, I determined, notwithstanding the 

 greatly diminished interest of sohtary travelling, to remain in Asia Minor, and 

 to endeavour to work out some of the principal objects which we had in view, 

 when we quitted England. Two of the most important of these objects, — a 

 minute examination of the geology of the Catacecaumene, and the ascent of 

 Mount ArgaBus, besides others of similar interest, I accomplished during the 

 summer of 1837. I propose, therefore, in the following remarks, to give an 

 account of the most eastern part of Asia Minor, which I then visited, and of 

 Mount ArgaBus, the summit of which had never been reached by any Euro- 

 pean traveller ; but I much regret, that my observations were not nearly so 

 perfect as they would have been with the assistance of Mr. Strickland, whose 

 knowledge of various branches of Natural History had been of the greatest 

 use during our previous journeys. 



In offering to the Society, the following account of the geology of that part 

 of Cappadocia, which extends from the great Salt Lake of Kodj-hissar, east- 

 wards as far as Caesarea and Mount Argaeus, I prefer describing the pheno- 

 mena in the order in which they came under my observation, to giving a ge-
