(Y\HE chief features of the district were briefly described, with 
a general account of the formations that are exposed throughout 
the county. These are comprised in the following main divisions 
in descending order: Recent and Pleistocene, Jurassic, Triassic, 
Permian, Carboniferous, and Pre-Cambrian. The first of these 
includes the river deposits and glacial beds. The Jurassic rocks 
comprise only the two lower subdivisions of the Lincolnshire Lime- 
stone and the Northampton Sand, together with the Lias. The 
Trias occurs in the usual two divisions of Keuper and Bunter. The 
Permian consists of breccia and marls, the age of which is to some 
extent doubtful. The Carboniferous is well exemplified in the three 
subdivisions of Coal-measures, Millstone Grit, and Limestone; but 
the lower beds are not of the importance they attain elsewhere. The 
Pre-Cambrian rocks are divisible into three main groups, as shown by 
Professor W. W. Watts—the Brand Series, the Maplewell Series, and 
the Blackbrook Series. Special attention was directed to the more 
important exposures of these rocks, and to the principal points in the 
local geology that are obscure and require further elucidation.

S the north-west of Charnwood Forest is approached the rocks 
become more altered, the faulting is greater, and igneous rocks 
are met with. The vent which ejected the rocks of the forest seems 
to lie in this direction. 
Bardon Hill.—The centre and part of the north flank are composed 
of rock resembling an igneous rock; evidence is given to show that 
this rock differs from the agglomerates found in the north-west area, 
with which it has hitherto been correlated. Certain rocks between 
the Bardon rock and the Peldar porphyroid seem to bear some relation. 
to the felsitic agglomerate.
