it is almost wholly calcareous, containing little or no siliceous 

 matter. 



Geologists will of course be anxious to learn whether these beds, 

 occupying a situation similar to that of the Paris strata, are identical 

 with any of them. I am myself too little acquainted with the 

 latter to form any opinion on the subject. I am inclined to think 

 however that the Maestricht rock differs from all the beds which 

 form the Paris basin. 



It would be departing too much from common language to call 

 it chalk ; but the gradual transition of the chalk into the freestone, 

 and the separation of the strata from each other by parallel beds of 

 flint, seem to be sufficient reasons for including it in the chalk 

 formation. 



When nearly at the southern extremity of St. Pierre I crossed 

 over to the right bank of the Meuse to examine a rock which rises 

 very boldly near a little town called Vise. This rock I found to 

 resemble the limestone of Derbyshire, containing all the fossils 

 characteristic of that formation, and like it frequently passing into 

 chert. The fossils most abundant are several species of anomise 

 and entrochi : the latter are more particularly abundant in the 

 chert. In some pieces I also found that species of coal which is 

 called anthracite included in veins of calcareous spar. 



In the country round Liege, distant about two leagues S.W. of 

 this place, there are (as is well known) extensive collieries.
