large quarries on the escarpment gave about 200 feet as the thick- 
ness of the Inferior-Oolite deposit between the Upper Trigonia-Grit 
and the Upper Lias, the one total confirms the other. 
The details obtained at the Hartley-Cottages well may thus be 
summarized :—

I am indebted to Mr. 8. S. Buckman for naming the ammonites. 
In connexion with the same water-supply scheme that required the 
deepening of this Hartley-Cottages Well, a new well was sunk near 
“the cottages at the northern entrance to the wood in Hartley Bottom ; 
and two trenches were dug—the one connecting the Hartley-Bottom 
well with that at Hartley Cottages; and the other, the well at the 
latter place with the Sanatorium. 
The sites of the wells and the courses of the trenches will be 
apparent from the small map (Fig. 1). 
_Wett in Harttzy Borrom.—This well was commenced in the 
Oolite Marl and left off in the Pea-Grit. Some of the pieces of Pea- 
Grit that were dug out were as blue as Forest Marble. 
PrpE- TRENCH coNNECTING THE Harritey- Borrom anp Harttey - 
Corragres Wrtis.—As already remarked, there appears to be a very 
slight fault at some 60 yards along the trench away from Hartley 
Cottages in the direction of the Hartley- Bottom well. Thence 
onwards, however, to within 150 yards of the latter well the trench 
was in the Clypeus-Grit, which was full of the ordinary fossils. 
Above the Clypeus-Grit exposed in the trench—especially about the 
middle portion—was a foot or more of tough, purplish clay—residual 
soil from the weathering of the Fullers’ Earth. In the stretch from 
150 yards of the well to the well itself, was observed evidence of the 
Upper Zrigonia-Grit (? Gryphite-Grit), Buckmani- Grit, Lower Trigonia- 
Grit, and Upper Freestone. 
_ PIPE-TRENCH BETWEEN THE Harrtry-Corraces WELL AND THE 
Sanatortum.—For the first 300 yards this trench was in the Upper
