The Upper Lias is about 230 feet thick, and from recorded obser- 
vations appears to be an almost wholly argillaceous deposit. In the 
bank by the road-side near the house called ‘‘ Firs Brake,” Upper-Lias 
clays, becoming somewhat sandy, are seen with tumbled Inferior- 
Oolite rock above, and near ‘‘ Daisy Bank” still more arenaceous 
Upper Lias is visible in an excavation fast becoming overgrown. The 
latter exposure orginated in an excavation made, so Mr J. W. Gray 
was informed, in order to obtain sand for mixing with the clay dug at 
the Leckhampton-Road (near the station) brick-works. How thick 
this sand-deposit is the Director has never been able to ascertain. 
About the year 1850, the actual junction of the Liassic and 
Inferior-Oolite Series seems to have been visible, and the details of the 
section were recorded by the Rev. P. B. Brodie. As the volume of 
the Quarterly Journal of the Geological Society’ containing this paper 
is an early one and therefore not readily obtainable, it has been deemed 
desirable to reproduce Brodie’s remarks (section, page 189). 
It will be observed that Brodie does not mention any conspicious 
sand-deposit at the top of the Upper-Lias clays. Immediately beneath 
the Belemnite-Bed (41 in section on page 189), he records a 3-inch 
deposit of a ‘‘brick-coloured and dark yellow sandy marl.” Recently 
Mr J. W. Gray told the Director that when a path was being constructed 
in the grounds of ‘‘ Firs Brake” a deep-red sandy marl, which had been 
excavated, attracted his attention. No doubt it was a continuation of 
this same bed. 
Although Brodie has not recorded a sand-deposit of any thickness, 
there is doubtless an arenaceous deposit present. It may be suggested 
that the sequence about the junction of the two series, the Liassic and 
Inferior-Oolite, is similar to that at Crickley Hill,? where in descending 
order we have the the Scésswm-Beds; micaceous, greyish-blue clay 
(1 to 2 feet); sand, yellowish indurated and very micaceous with some 
ferruginous nodules (4 to 6 feet); and blue clay from which water is 
thrown off. Thus, if only the actual junction of the two series were: 
exposed to view, it would seem as if no sand deposit were present, 
whereas it really occurs beneath a clay capping. 
The Inferior-Oolite rocks between the Upper Lias and the CZypeus- 
Grit measure about 200 feet, or between the Upper Lias and Upper 
Trigonia-Grit about 194 feet. In the district between Bath and 
Frome the Upper Z?zgonia-Grit, represented usually by a more or less 
conglomeratic deposit, rests generally directly upon the Upper Lias, 
and in the hill-country east of the Rissingtons, near Burford, the Clypeus- 
Grit rests directly upon the Upper-Lias clays. In the North Cottes- 
wolds the rocks between the Upper Lias and the CZyfeus-Grit attain 
a much greater thickness than at Leckhampton Hill. 
Bed 41 of the section, given on page 189, the lowest hard bed of 
the Inferior-Oolite Series, Brodie considered worthy of the denomina- 
tion ‘* bone-bed.” ‘‘ The bones, scales, coprolites, and teeth are very
