102 THERMAL WATERS OF ASIA MINOR. 



country in its neighborhood to possess any other than the or- 

 dinary properties of water. 



The geological character of the contiguous country has 

 nothing in it that would induce one to suspect the existence 

 of such abundant sources of warm water. The plain of Eski- 

 Shehr appears to be one of those extensive lacustrine regions 

 so common in the western portion of Asia Minor; the deposits 

 consist of a consolidated breccia. Imbedded we find the rocks 

 of the neighboring mountains, as well as the meerschaum or 

 silicate of magnesia, so extensively worked for exportation. 

 Thermal waters are obtained in numerous parts of the plain 

 as well as at Eski-Shehr. 



THERMAL WATERS OF TROY. 



Near the plains, in which are supposed to have been situated 

 the ancient city of Troy, are numerous sources of thermal 

 waters, of several of which I procured specimens ; only two, 

 however, have been analyzed, the others not having arrived at 

 my laboratory. These springs are those alluded to by Homer, 

 and they have enjoyed more or less reputation from the time 

 of the Trojans to the present date. The two that I have ex- 

 amined are saline and their sources near each other. Analysis 

 shows them to be identical. The physical properties will be 

 alluded to when the other waters from this locality have been 

 examined.
