CONCHOLOGY., 
may venture to offer it as a subject of much higher 
consideration and interest to the student in geology, 
as one of the means of elucidating the relations of 
the different parts of the earth, to which we can or 
may have aecess. The connexion of all the parts 
of Natural History with geological knowledge, has 
at length been considered as a powerful instrument 
in the promotion of this sublime science, which 
though as yet in its infancy, has, hke the young 
Herculus, given glorious promise of a sound and 
vigorous maturity. 
The philesopher, for example, will examine with 
delight and wonder, the vast mass of diluvian 
marine shells, mixed with siliceous sand in its 
several degrees of induration and cementation, and 
totally different from the sand of the adjacent 
shores, deposited near the very summit of Haldon 
Hull, to the north of the town of Teignmouth, and 
enquire, with busy curiosity, by what process of 
nature they have been fixed there, at the height of 
eight hundred feet above the level of the sea. 
Probably a vortical deposition at the time of the 
general deluge, round the summit of the original 
mountain. Comparative measurementof the altitude 
of this testaceous stratum with other similar depo- 
sitions, might lead to some valuable conclusions as 
to the height of the flood, in this region of the glvbe, 
and teach us where to seek for their level in other 
maritime mountainous countries. 
This very interesting natural curiosity is just 
beyond the town of Teignmouth, in a bye road
