diameter, which imply that they were carried by ice in a sea 

 of sufficient depth to float hirge icebergs. 



4th. After this subsidence, the re-elevation and partial 

 denudation of the cretaceous and glacial beds took place 

 during a general upward movement, like that now expe- 

 rienced in parts of Sweden and Norwaj''. 



In regard to the lines of movement in Moen, M. Puggaard 

 believes, after an elaborate comparison of the cliffs with the 

 interior of the island, that they took at least three distinct 

 directions at as many successive eras, all of post-glacial date; 

 the first line running from E.S.E. to W.N.W., with lines 

 of fracture at right angles to them; the second running from 

 S.S.E. to N.N.W., also with fractures in a transverse direc- 

 tion; and lastly, a sinking in a IST. and S. direction, with other 

 subsidences of contemjioraneous date running at right angles, 

 or E. and W. 



When we ajiproach the northwest end of Moens Klint, or 

 the range of coast above described, the strata begin to be 

 less bent and broken, and, after travelling for a short distance 

 beyond, Ave find the chalk and overlying drift in the same 

 horizontal position as at the southern end of the Moens Klint. 

 What makes these convulsions the more striking is the fact 

 that in the other adjoining Danish islands, as well as in a 

 large part of Moen itself, both the secondary and tertiary 

 formations are quite undisturbed. 



It is impossible to behold such effects of reiterated local 

 movements, all of post-tertiary date, without reflecting that, 

 but for the accidental presence of the stratified drift, all of 

 which might easily, where there has been so much denudation, 

 have been missing, even if it had once existed, we might 

 have referred the verticality and flexures and faults of the 

 rocks to an ancient period, such as the era between the chalk 

 with flints and the Maestricht chalk, or to the time of the 

 latter foi'mation, or to the eocene, or miocene, or older
