continuation of the direction of Saltholm, belong to this lime- 

 stone ; they appear to have been derived from some compact 

 bed situated at a greater depth. 



The following rock occurs at the Klint, or cliff of Stevn. 

 It is a true chalk, and constitutes the last bed in the cliff; it 

 contains flint [silcx) in a nearly horizontal position : there is 

 however a slight inclination to the W.S.W. The most per- 

 fect regularity reigns throughout this formation, the beds of 

 which are completely pai'allel to each other. To the chalk 

 succeeds a bed of clay three or four inches thick, and then a 

 limestone bed one foot thick. The clay bed contains car- 

 bonaceous matter in its lower part, and sharks' teeth, PcctenSy 

 and imperfect impressions of plants are found in it. The lime- 

 stone is hard, and full of green particles ; it passes insensibly 

 into a cretaceous rock and coral-limestone. Its fossils differ 

 from those of the chalk, and consist of the genera Cerithium, 

 Trochus, Natica, Cypnca^ Area, Mytilus; and in zoophytes, 

 Favosites and Turhinulites. To this limestone, which the author 

 names Cerithium limestone, succeeds another consisting of 

 corals united by a marly mass ; it is the corallite limestone of 

 the author. It contains siliceous nodules, which sometimes 

 take an ellipsoid form ; the siliceous nodules resemble horn- 

 stone, and the beds are compact. The fossils found in this 

 limestone are the same with those of the true chalk. It is co- 

 vered by an irregular mass of angular fragments of the same 

 limestone and flint {silex) cemented by chalk. 



The limestone in the quarries of Faxoe is very pure, and 

 is formed of slaty and compact limestone, with jiorous coral 

 beds. Varieties similar to the corallite limestone and marly 

 chalk are here also found. Generally speaking, the Faxoe 

 limestone is analogous to the cerithium limestone of Stevus- 

 Klint ; j)art of the same fossils are found in it, but the Faxoe 

 limestone also contains other species, some of which have only 

 been found in rocks above the chalk: for example, CyprccOi 

 Inisus, and Solarium. 



The cliffs of the isle of Miien are composed, accoi'ding to 

 the author, of a marly cretaceous rock with beds of flint (s//f.r), 

 a conglomerate of chalk and white sand cemented by a creta- 

 ceous substance, a gray clay, yellow white and red sand, yel- 

 low clay mixed with sand, and of conglomerates of primitive 

 rocks. The clay and sand contain rolletl pieces of jnimitive 

 rocks; a circumstance of frequent occurrence in Dcmiuuk. In 

 the gray clay they are small, and rarely more than two or three 

 inches in diameter ; in the yellow clay and sand there are some 

 larger. The cretaceous rock in many ])laces contains nodules 

 of "strontian, ul iriany pounds weight, with corals iiiul bivalves.
