Shows on archaeological evidence that whereas in Elanders the land 



rose from the 7th to the 10th century, the Adriatic coast was sinking 



from 530 a.d. to the beginning of the 11th century. At present the 



reverse action is taking place : the north-western Adriatic is rising, and 



the Elemish coast is sinking. G. A. L.

 Concludes that the specimen exhibited did not support the view that 

 a high temperature is necessary for the conversion of coal into

Yaughait, D. Physics of the Internal Earth. Phil. Mag, ser. 4, 

 vol. xlviii. pp. 237, 238 (Brit. Assoc). 



The author speaks of the terrestrial crust as reposing on lava of a 

 declining temperature, and accounts for earthquakes by supposing 

 solid material to be formed at the internal surface of the crust, and 

 sometimes to move upwards, as, so to speak, an avalanche. These 

 avalanches convey heat upwards, and tend by fusion and erosion to 

 lessen the thickness of the crust in certain spots, which thus become 

 the localities for volcanoes. Chemical reasons are adduced to show why 

 the formation of buoyant solids must occur. E. D.

 heat." G. A. L.
