This, which I had then no means of accurately measuring, I 
find to approximate so nearly with Mr. Strickland’s detailed sec- 
tion, as given in the 6th vol. of the Journal of the Geological 
Society, that I am induced to think the section as now exposed 
reaches very nearly to the Lias; at all events when I saw the 
Lias and Oolite in contact at this very spot there was a sudden 
and abrupt transition from the Oolite to the Lias, there being at 
this place none of the Inferior Oolite Sands of the Ordnance 
Surveyors. 
In reference to the basement bed of the Oolite, I quote from 
Mr. Strickland’s paper the following remarks : — 
“(7) Ferruginous beds, consisting of coarse Oolite in the upper 
part, and of a very peculiar large-grained Oolite or Pisolite 
(‘Pea-grit’) in the lower. A few miles to the south the Pisolite 
disappears, and is replaced near Painswick and at Haresfield 
Hill by strata containing ferruginous oolitic grains in a brown 
paste. This is the precise equivalent of the well known Oolite of 
Dundry, near Bristol, which may be recognized as far off as 
Bridport, on the Dorset coast. At Leckhampton the Pisolite 
rests upon a few feet of ferruginous Oolite and Sand; the total 
thickness of this portion of the series is 42 feet.” 
The observations here made, coupled with a somewhat length- 
ened examination of these lower Oolite beds, both north and south 
of Leckhampton, induced me to venture to suggest to the meeting 
of the Geological section of the British Association, and again to 
our Cotteswold brethren at Leckhampton Hill, an opinion that 
the Silicious oolite, by which the Pisolite at Stow, Winchcomb, 
Leckhampton, and Crickley is underlaid, was the representative 
in time of the Oolite Sands of the Stroud and Painswick districts, 
an opinion which I am still inclined to favour; however, the 
details of this matter would be much too long for an address like 
the present, but I still hope to be able to find time to arrange the 
material I have got together on this subject before the close of 
the present session. 
To recur to the doings at this meeting. At Leckhampton the 
party was joined by two ladies who kept up well with the field 
Naturalists along the top of Leckhampton Hill to Hartley Bottom 
and the Seven Springs.
