heights about Bath, and the indented line of the Mendips. Long 
Knoll, 973 feet above the sea, being the extreme west point of the 
chalk of Salisbury Plain, occupies a magnificent point of view. In 
addition we have Prospect Hill, Whiten Hill, Titherton Hill, Rod- 
mead Hill, Whitesheet Hill, and Morley Combe Hill. Alfred’s 
Tower occupies Kingsettle, one of the loftiest of the Green sand 
hills (800 feet above the sea). 
This district possesses considerable variety of soil and surface, 
and is in many respects a remarkably favourable one for the botanist, 
its Flora having, from time to time, been well investigated by many 
excellent observers, viz., the late Aylmer Bourke Lambert,! Pro- 
fessor David Don, and William Peete, Esq., who have each dis- 
covered plants of great rarity. For a list of most of them (in 
addition to the author’s own researches), with many valuable 
remarks, he was indebted to the kindness of the lamented Professor 
Don.

The middle district has its northern boundary defined by the 
Kennet and Avon canal, its eastern by the Salisbury Avon, and its 
south-western by the railway from Salisbury through Warminster, 
Westbury, and Trowbridge, the area being about 220 square miles. 
This district has a small portion of the oolitic strata in the neigh- 
bourhood of Trowbridge, Steeple Ashton, Seend, and Poulshot. 
The coral rag is particularly well developed at Steeple Ashton, (a 
classical spot to paleontologists,) and the surrounding neighbour- 
hood. Here the corals of the coral rag are found in greatest 
abundance and perfection, showing that this part of our island, at the 
time of the deposit, clearly existed in the condition of a coral island in 
an open sea. The thickness of the bed is about 400 feet, large por- 
tions of it being frequently made up of the remains ofa single species. 
An earthy calcareous freestone full of fragments of shells, rests 
immediately upon it, surmounted by a fine grained ferruginous 
sandstone, slightly oolitic in structure, and containing a few fossils
