LOWER LIAS: CHIPPING CAMPDEN. 155 
Mr. G. E. Gavey in 1853;* subsequently many fossils were

A full and interesting account of the railway-cuttings at the 
Mickleton Tunnel, near Chipping Campden, was published also 
in 1853 by Mr. Gavey. J The hill above Mickleton Tunnel 
rises to an elevation of 490 feet, and is formed of Lower Lias and 
Middle Lias shales and clays, overlaid by Marlstone and Drift. 
The Drift proved to be 76 feet thick, and consisted of loamy sand 
and gravel, and red clay with blocks of Marlstone. 
Beds of Lias shale upwards of 80 feet thick were exposed. 
The upper portions contained nodules and slabs of ironstone, and 
thin beds of sandstone, and these yielded a number of Echino- 
dermata, including Uraster Gaveyi, Tropidaster pectinatus, and 
Ophioderma, together with Ammonites and other fossils. The 
general list published by Mr. Gavey shows that Middle and 
Lower Lias were exposed : and the beds correspond with those 
opened up in the railway-cutting near Chipping Norton. The 
fossils just mentioned probably belong to the Middle Lias (zone 
of Ammonites margaritatus). The lower portions of the clays 
belong to the zone of A. capricornus (or A. Henleyt), and 
probably to lower beds, as indicated by the presence of A. plani- 
costa, &c. Prof. Hull mentions the occurrence of Hippopodium 
ponderosum. Layers of crushed oysters were noticed by Mr. Gavey, 
also plant-remains and large pieces of carbonized wood. Of this 
lignite, he remarks that " one piece was about 7 feet long, and 
more than 1 foot wide, but, being in a crushed state, it was only 
1^ inch thick ; it was converted into jet. Other pieces were of a 
dark brown colour, impregnated with iron-pyrites." 
A deep boring made at Mickleton Wood, near Chipping 
Campden, for Mr. S. G. Hamilton, of Kiftsgate Court, has proved
