PROF. J. BUCKMAN ON THE MIDFORD SANDS, 737 
confounded two beds, in which he has been preceded and followed 
by the authors quoted. 
The Cephalopoda-bed at Midford, Bradford Abbas, Halfway 
House, and Bridport is situated near the top of the Inferior Oolite, 
while the Cephalopoda-bed of Dr. Wright is situated at the bottom 
of that rock in Gloucestershire, and we have traces of this latter 
below the sands in Dorsetshire. 
The so-called Midford Sands are the equivalents of the Ham-Hill 
building-stone, of the Doulting oolites, of the brown freestones and 
ragstones of the Cotteswolds, and of the grand sand section at Brid- 
port Harbour. 
In the accompanying diagram (fig. 1, p. 738) are placed side by 
side the Midford section and the Haresfield section. 
The detailed section at Midford station is as follows in descending

We take it, then, that the sections at Crickley Hill and Haresfield 
Beacon, in Gloucestershire, in their shelly oolites and ragstones, are 
the exact equivalents of at least 120 feet of the sands which at 
Midford and other places in Somerset, Bradford Abbas and Sherborne 
in Dorset, are identical. 
These sands, as we have before shown, are interrupted by occasional 
beds of stone both at Midford and Bradford, which stones are usually 
as full of comminuted fossils as the shelly oolite of Leckhampton 
Hill; many of them, however, are capable of being identified, and 
the list to be given presently will show much the same fossils as 
occurring in both.
