a similar superposition may be observed. In one instance, a 

 large bed of yellow sand and bluish-gray clay are completely 

 inclosed in the chalk ; in other places, the l>oundary between 

 chalk and clay is parallel to the beds of flint in the chalk. In 

 one instance, there occurs a bed of conglomerate, where the 

 large rolled primitive rocks are cemented together by a brown- 

 ish yellow clay, the bed being parallel to the boundary between 

 the chalk and sand. The fossils of Moen are those of the chalk. 

 I have seen the following : Three species of Pecten ; two species 

 of Terebratula, (of which one, probably T. Defrancii, is in the 

 collection of his Highness the Prince Christian of Denmark.) 

 Ostrea vesicularis ; one species of Gryphcea ; Ananchytes 

 ovata ; Ananchytes pustulosa ; Cidarites variolaris ; Belemni- 

 tes mucronatus ; four species of Flustra ; one species of Tur- 

 binolia, which seems to be the same as that from Taxoe and 

 Stevensklint. The Ananchytes pustulosa, the Cidarites vario- 

 laris, and the Turbinolia, are in the rich collection of his High- 

 ness the Prince Christian of Denmark. 



There occur still another range of hills on this island, much 

 lower, however, than the cliffs now described. It has a south- 

 west and north-east direction, and forms partly low cliffs on 

 the east side of an arm of the sea called the Noer. They con- 

 sist of a white marl, softer than the rock from the real cliff, 

 containing rarely fossils, but alternating with the similar bluish- 

 gray marly clay, as that which is found accompanying the 

 chalk of Moen. I consider these beds as small depositions of 

 a similar kind as that of the cliffs of Moen ; and many other 

 beds of the same kind occur in different places of Denmark, 

 viz. at Holsteinburg on Sealand, at Sneghog in Jutland, at 

 Caleling in Jutland, &c. all of which are beds of white soft 

 marl, accompanied with bluish gray clay, and subordinate to 

 the great deposition of sand, gravel, and boulder-stones of this 

 country. * 



If we recollect the facts now related, we may consider the suc- 

 cession of strata in the eastermost part of Denmark as follows : 



* I have convinced myself that the chalk of Itugen is of a similar na- 

 ture, and forms subordinate beds in the gravel. It is principally evident 

 on the promontory on which the ruins of Arcona still are visible, where a 

 huge mass of chalk, at least fifty feet thick, rests upon bluish-gray clay, with 

 small broken pieces of flint and granite, subordinate to loam and sand.
