180 THE SERPENTINE ROCKS. 



bouring limestone hills, by colour as well as form, 

 the decomposed surface of the rock assuming a 

 pink or purple tint. The south side of the bay 

 of Macri, much of the country around Dsedala, 

 the hills east of Cadyanda, bounding the plain of 

 Macri, and many hills in the upper part of the 

 valley of the Xanthus, are formed of this ser- 

 pentine, which is possibly more ancient than the 

 scaglia, and may have have been only a secondary 

 agent of a deep-seated disturbing force. This 

 rock extends through Caria as far as Marmorice. 



The mountain passes between Balbura, (Eno- 

 anda and Tremeely in the Cibyratis, are for the 

 most part also composed of serpentine. The 

 rock here is not so schistose, very shining, 

 and steatitic in appearance, of a vivid green, or 

 bright red colour, and often passing in mineral 

 character from common to precious serpentine. 

 It is evidently a cause of disturbance of the 

 scaglia, isolated masses of which are borne up 

 upon it, and in places the limestone beds are 

 much contorted. Not far from Tanger, and 

 near the Gul Hissar, forming the eastern boun- 

 dary of part of the Cibyratic plain, are hills of 

 serpentine, apparently of the same date with that 

 of Balbura. Also in the immediate neighbour-
