M. Keilhaifs Theory of Granite and other Rocks. 403 



tions on this subject were already published in 1826 ; and a 

 celebrated German Professor said to me plainly at that time, that 

 there must be some mistake in the observation, in short, that such 

 a state of things was not possible ; and truly it can hardly be 

 reconciled with some of the theories which have hitherto at one 

 time or another been generally received. I so much the more, 

 on this account, invite geologists to investigate this fact for 

 themselves ; and convenient localities are to be found without 

 much difficulty near Christiania, where such appearances are 

 to be seen.* 



Let us now for the moment leave these phenomena, and pass 

 to considerations of a different description, which are also 

 among the most important connected with our territory, on ac- 

 count of the inferences they furnish. I allude to certain tran- 

 sitions which take place among some of the mountain-rocks.

Containing the Mean of the Meteorological Observations made at Regent 

 Terrace, Edinburgh for each month of the year 1837, Lat. 55° 57', height of the 

 barometer above the mean level of the Sea 246 feet. 



rocks in massive formations between Dresden and Meissen, deserve specially 

 to be examined in the same point of view. 



* The section of Tor-nid-neon at the head of Loch Kanza, in the island of 

 Arran, may be mentioned as one of many instances in Scotland where masses 

 resembling fragments of slate in granite have the same position as the bound 

 ing strata of slate Edit'.
