312 The Rev. W. E. Hony on Maestricht. 



them is greater, and towards the upper part of the hill is as much 

 as eight or ten feet. 



These flints frequently contain organic remains; of these the 

 most common is the belemnite ; shells also and silicified wood are 

 not uncommon. 



The height of the hill above the Meuse is I should imagine 

 about 150 feet. 



To the eye the strata appear to be perfectly horizontal. As 

 however, I found the chalk gradually rising as I proceeded in a 

 direction nearly south, it is probable that there may be a very 

 slight inclination towards the north. My stay was too short to 

 enable me to give any account of the numerous fossils of this rock. 

 I may however mention that those which I found most common 

 were various species of corallines and madrepores, (particularly the 

 fungites ;) belemnites ; numulites ; several species of echini, amongst 

 others, a small one having the mouth in the centre of the base and 

 vent lateral ; several kinds of oysters and pectines. I was also for- 

 tunate enough to find a very beautiful baculites with turrited articula- 

 tions, but this I believe is very rare. It is described in the 3d vol. 

 of Parkinson's Organic Remains, p. 142. 



The top of the hill is covered by a bed of gravel, in some places 

 of considerable thickness, containing rolled pebbles of flint, white 

 quartz, graywacke containing veins of quartz, and a red sandstone. 

 I believe that this gravel rests immediately on the strata which 

 compose the hill, and that the beds of sand which M. Faujas de 

 St. Fond thought he perceived under the gravel are only a part of 

 the rock in a state of decomposition. 



It is rather extraordinary that this celebrated naturalist should 

 have described the freestone rock of Maestricht as " un gres 

 quartzeux faiblement lie par un gluten calcaire." It appears that
