NATURAL HISTORY. 
nuted fragments of this description, of a brownish 
grey colour, with here and there a more distinct 
portion of the fossils intermixed ; the lower beds, 
which have red and white veins, are crowded with 
larger and more distinctly formed remains, 
These are referable to a different and far earlier 
period than the bones of the various species of 
mammalia that occur in the fissures and caves of 
this formation. The one being amongst the most 
ancient, the other amongst the most recent vestiges, 
that remain of the revolutions that have occurred 
onthe surface of the globe. Fissures and caverns 
of this kind are of general occurrence in compact 
Lime rocks, not only in this Island, but on the 
Continent where they have long been objects of 
curiosity ; the most remarkable ones in our district 
are those of Kent’s Hole and the Chudleigh rocks, 
the former of which has been very diligently ex- 
plored, and we are looking forward with great 
interest, to the publication of a work that has been 
announced by a gentleman of Torquay, which will 
contain an account of the Treasures that have there 
been unearthed. They are all more or less filled 
with a Diluvial detritus of mud, sand, angular 
fragments of Transition rocks, &c., and stalactites, 
In those at the Chudleigh rocks, numerous pebbles 
of chert and chalk flint, and Transition slate are 
mixed with the mud that forms the principal sub- 
stance, and fills up the fissures to the very surface 
of the soil; where ever occurring they appear to be 
connected, and so often confluent and inosculating
