OF LEICESTERSHIRE COLLECTED BY W. S.

(Concluded from page 35.) 
V.—Rocks probably of Carboniferous Age.—Sandstones, 
Mudstones, &c. 
(49.) An angular fragment, slightly rounded at the edges, 
of a hard, fine-grained, somewhat micaceous sandstone. 
(? Carboniferous.) (71.) An angular fragment of a fine-grained, 
quartzose, sedimentary rock, with irregular rusty spots, the 
origin of which is difficult to determine. This might be 
Carboniferous. (91, 92, 97, 98, 99, 132, 136.) Seven 
specimens of sandstone, often somewhat micaceous, weathering 
brownish or reddish ; five collected from Woodville, Overseal, 
or Measham ; one a very close, compact grit or quartzite, 
with bedding apparently much contorted. Four specimens are 
striated or indented. One of them is a fine-grained grit of 
dull reddish colour ; and another is a large, flattish, rounded 
pebble, 7in. x 6in. x 2Jin., of a fine-grained, hard quartzose 
sandstone, with specks of felspar. (75, 76.) Two pieces of 
hard clay, much slickensided and polished. From Linton 
Colliery, and from brickyard N.W. of Woodville. Certainly 
Carboniferous. (44.) Some kind of argillite. It has a 
slightly brecciated look in parts. (? Iron-stained rock from the 
Carboniferous.) (96.) From Overseal—a fairly angular frag¬ 
ment of rather hard siliceous mudstone, somewhat iron-stained, 
with plant remains. Certainly Carboniferous. (51.) Probably 
a hard mudstone, with holes, which were occupied by crystals 
of pyrite, now rotted away. (52.) This specimen appears to 
Description of Figures. 
Plate 2. —Sketches (drawn by Mr. Gresley) of boulders from the 
Permian breccia at Coton Park Colliery. 
Fig. I.—A boulder of grit or sandstone, with five or six striations, 
about 10 inches long, on the flattest surface. 
Fig. II.—A boulder of similar materials, with many white fragments, 
(? felspar) about the line C D. Haematite spots (? pebbles), 
blotches, and streaky patches about the horizon H. The 
face of the boulder from A to B, and half round the mass, 
is well smoothed, but not polished. 
Plate 3.—Plan (drawn by Mr. Gresley) to indicate the distribution of 
the largest fragments in the Permian breccia, and the direc¬ 
tion from which they have probably come.
