archaeological, is chiefly taken, as far as the geology is concerned, 

 from the writers just quoted. 



It was not till 1866 that the region was again visited by 

 geologists, but in this year Fouque, as well as Reiss and Stubel, 

 on their return from study of the Santorin eruption, examined 

 the localities, Fouque's account of Methana 1 is short, but he 

 gives an excellent description of the Kaimeni eruptive centre, 

 whose crater he was the first to discover, and which he identified 

 as the site of the eruption mentioned by Strabo, Pausanias, and 

 Ovid. 



Reiss and Stubel 2 spent a day on ^Egina, going from the 

 harbor to the temple, thence along the eastern slope of the East 

 Ridge to the summit of Mt. Oros, and thence to Perdika ; and 

 a little longer time on Methana, of which they explored the 

 northwestern part, including Kaimeni and Mt. Chelona. Their 

 account is very readable, their descriptions, as far as they go, 

 very good, and the conclusions they draw from their observations 

 in general, just. A short petrographical description of the rocks 

 collected by them is given by v. Fritsch, which, being based 

 almost entirely on a megascopical examination, is necessarily 

 imperfect and unsatisfactory. They also give a geological map, 

 which, however, does not go into details, and which is not cor- 

 rect in its orographical features, their changes of the British 

 Admiralty Chart (which they complain of) being much for the 

 worse. They are incorrect also in assigning the limestone moun- 

 tain masses of the north of ^Egina to the Tertiary rather than to 

 the Cretaceous period. Neumann and Pertsch 3 devote some space 

 to this region, but their account is entirely taken from the three 

 preceding writers, as is the case with Philippson, 4 whose field 

 of study did not include JEg'ma, and who did not visit 

 Methana.
