EUKOPE. 87 



plateaux or Karst district of S. Europe is traced to decomposition of 

 t^e limestone under circumstances that prevented the washing away of 

 the detritus so formed. It is of various ages ; in the Karst, where it 

 contains Hippotherium, it is of Miocene age. The red silt of the 

 'Challenger' expedition is alluded to as a proof of silica and iron 

 in calcareous organisms. E. B. T.

Close to the Propylaea a Nerincea was found, which proves the Acro- 

 polis rock to be Mesozoic ; on the other hand, the limestone of Hymet- 

 tus alternates with crystalline schists ; its age is not certain. E. B. T.

Preliminary notice of the geology of the island of Cos between 

 Cnidus and Halicarnassus. The structure is complex, the formations 

 being : — Crystalline schists with included marbles, Hippurite-limestone, 

 several members of the Tertiaries and eruptive rocks. Trachytes, &c. 

 There is an unconformity between two parts of the marine Pliocene. 

 This island is the most northern of the archipelago at which the 

 Pliocene occurs. E. B. T.

 1000 parts of this water contain 12*55 parts mineral constituents ; 

 and of those O'OIO consist of iodide of magnesium. Temp. 8° C. 

 Several borings have shown that a bed of postglacial clay, 100 feet 

 thick and of some extension, is impregnated with iodine and chloride 

 salts. E.E.
