Coral Limestone of Faxoe. 

 When we endeavour to trace the upper limestones above described from 

 the sea-cliRs into the interior of the country^ we find that they are entirely 

 concealed beneath the covering of breccia and the boulder formation, but 

 about ten miles south-west of Stevensklint, the inferior or Faxoe bed, is found 

 in great thickness on the summit of one of the highest hills in Seeland. Its 

 existence has also been detected at some intermediate spots by the digging of 

 pits and wells. Large quarries which I visited with Dr. Forchhammer have 

 been opened in these beds at Faxoe, and they supply excellent building stone, 

 consisting of a hard yellowish limestone, the thickness of which can be traced 

 to the depth of forty feet, without any signs of coming to an end. Sometimes 

 corals are very abundant in this stone, so that large masses appear entirely 

 composed of zoophytes. Two species are peculiarly abundant, Cari/ophi/llia 

 Faxoensis, Beck*, (see figure 4), and another f (see figure 5.). In some 

 places there are patches of coral cemented together by white chalk, but with 

 these exceptions, no portion of our oolitic rocks can less resemble ordinary 



* I have to acknowledge the kindness of Dr. Beck in supplying me with a faithful drawing of 

 this coral, which he has had made from a specimen in the collection of H. R. H. Prince Christian. 



f This coral approaches to the genus Isis in having stony articulations, which are concentric- 

 ally striated at each end, but it differs from Isis in the younger branches being hollow, and in other 

 particulars.
