into two large divisions, and into five smaller ones, and his 
remarks upon them are extremely interesting, especially in 
comparison with what we have observed in the Notgrove dis- 
trict. He divides these beds as follows: — 
A. Pholodamya Grit. 
c B. Trigonia Grit. 
Spinosa Stage C. Gryphite Grit. 
D. Rubbly Ragstone. 
Fimbria Stage : Oolite Marl Series Bree oo 
The corresponding beds in the Notgrove District can easily be 
seen, but it is curious to note that he observes that series A is 
of inconsiderable thickness in the Northern Cotteswolds, a 
statement which these new cuttings do not bear out. In fact, 
from the bottom of the Oolite Marl upwards we have a far 
greater extent of beds in every way than any other district in 
the Cotteswolds exhibits. Dr Lycett’s arrangement of these 
beds in the manner shewn above seems somewhat arbitrary. 
It was certainly tempting to arrange in one series the large 
mass of Freestones and bastard Freestones, and in the other 
the Ragstones, because the line seemed so easy to draw. But 
in our district we meet with other conditions, and we have a 
Freestone in the middle of the Ragstones. In the Stroud area 
we have a marked division between the Freestones and the 
Ragstones, so much so that the former have been classed as the 
Lower Division of the Inferior Oolite, and the latter the 
Upper. In the Notgrove district our division seems to be at 
the Bored bed at the base of the upper Trigonia Grit. In 
Dorsetshire the division between upper and lower portions of 
the Inferior Oolite is drawn at the base of the Humphriesianum 
zone, and when this is absent naturally at the base of the 
Parkinson. 
During the course of these investigations the question of 
the zones to which the different beds belong, or in other words, 
their true correlation with the beds of the Inferior Oolite, 
which occur in Dorset and Somerset, has naturally occupied 
my thoughts. It was among the Dorset and Somerset beds 
that I first made acquaintance with Geology, and I have
