408 Revieivs — Santorin and the Kaimeni Islands. 



The author also acknowledges the great assistance he has received 

 from the works of M. Deshayes, and mentions the paper by the late 

 Mr. Smith, of Jordan Hill, as the only work hitherto published on 

 the Tertiary fossils of Portugal. 



The author intends giving a summary of his results in the last 

 part of the work, when all the species will have been described.

rCH interest was excited during the early part of the past year 

 by the announcements received in this country of repeated 

 igneous outbursts having taken place in the Kaimeni Islands, a group 

 of small volcanic islands situated in the Gulf of Santorin, formed by a 

 large island of that name in the Greek Archipelago. From Greece, 

 Germany, France, and England numerous scientific investigators re- 

 paired to study the nature of its phenomena. We have already 

 (Geological Magazine, 1866, Vol. III. pp. 222 and 263) given 

 some account of these interesting observations and their bearing 

 upon volcanic phenomena elsewhere. The authors of the present 

 work furnish not merely an account of the changes produced by 

 volcanic action in these islands, but, by means of maps and photo- 

 graphs from carefully executed relievo models of the islands them- 

 selves, they have laboured — and we think successfully — to convey 

 to the mind a picture of the theatre of these disturbances and the 

 changes produced both upon the island and the surrounding sea-bed. 

 These island- volcanoes offer some interesting points of comparison 

 with other volcanic areas. They appear also to confirm two important 

 points in connexion with volcanic action. Firstly, that the volcanic 

 cones of the Kaimeni islands, though differing in other respects, 

 coincide completely with the cones of eruption of other volcanoes, 

 and afford no support to the elevation hypothesis ; secondly, here, too, 

 as in many other localities, the craters already existing were not con- 

 cerned in the later eruptions, the volcanic agencies mostly finding it 

 easier to force a new passage for the materials thrown out, than to 

 reopen the older ones. 



Besides the three plates which accompany the description, the 

 authors announce that four other explanatory maps and views of the 

 Kaimeni islands may be obtained from Messrs. Triibner and Co. as a 

 separate supplement to their work, giving the configuration of the 

 island before the eruption and also on the 30th May, 1866, with the 

 islands of George I. and Aphroessa in active eruption. This plate 

 gives the best idea of the relation between the supra and sub-marine 

 parts of the islands. They are greatly to be recommended for the 

 use of geologists.
