I proposs, in the following observations, to introduce to my asso- 
ciates of the Cotteswold Club a notice respecting the Oolitic deposits 
in the neighbourhood of Bath, with reference, more particularly, to 
some peculiarities presented by the Inferior Oolite beds in that 
district, and to the relations which they offer to those of the 
Cotteswolds. 
In the course of the late autumn I was enabled to devote three 
weeks to the study of the Geology of the Bath district, in which I 
had the advantage of the frequent companionship of the well-known 
and accomplished Palceontologist, Mr. Charles Moore, to whose 
guidance I owe it that I was enabled to visit many points of interest 
and importance which would otherwise have escaped my obser- 
vation. 
My remarks having reference more particularly to the beds of the 
Inferior Oolite, it is not my intention to do more than to glance 
cursorily at the underlying clays, of the extent and peculiarities of 
which it is not easy to form a correct estimate ; as, in the immediate 
neighbourhood of Bath, the Lias is rarely exposed to any extent, and, 
excepting in well-sinking or in digging the foundations of houses, 
few opportunities offer for its examination. 
Lonsdale, in his Memoir on the Oolitic district of Bath, in the 
8rd Volume of the Transactions of the Geological Society, estimates 
the entire thickness of the Lias in that vicinity at somewhat less 
than 300 feet, and probably this may be viewed as a fair approximate 
average; but the thickness of the deposit varies considerably in 
different localities. In the Charlcombe Valley, it certainly exceeds
