PERMIAN BRECCIA OF LEICESTERSHIRE. 
Mar., 1892. 
be a fine-grained mudstone, with curious greenish spots ; most 
probably a variety of clay-ironstone, showing a certain amount 
of concretionary action. (7, 36, 73, 126, &c.) Olay ironstones 
occur with cone-in-cone structure ; this, in three or four 
instances, is very well developed, in others it seems to be more 
slightly marked. One is from Overseal, others from 
Donisthorpe and Stanton. (8, 27, &c.) Many specimens are, 
more or less, impregnated with iron oxide. One consists of 
quartz grains, in a few cases rounded, but usually rather 
angular, cemented with haematite, which seems sometimes to 
have acted corrosively on the quartz. In another, rather 
angular fragments of quartz (a little of which is compound) 
and of felspar are similarly cemented. (6, 13, 14, 15, 134, 
137, &c.) A large number of rocks are “burnishers” 
(including one from Packington and one from Overseal); 
these, or similar specimens, have been already described by 
Mr. Gresley.* The fossiliferous specimens are, in many cases, 
haematite nodules or rock impregnated with haematite. (33.) 
A quartz grit, with specks of (?) felspar, cemented by red iron 
oxide, contains a small cylindrical cast, like an organism. 
(70, 116.) In other ferruginous specimens are obscure remains 
of plants. (140, 141.) Two, consisting of haematite, one very 
earthy, contain apparently stigmarian rootlets. (142.) One 
haematite pebble includes a structure which Mr. Gresley has 
suggested may be a worm-cast or tube. Others contain leaf 
impressions (143), one, in a haematite pebble, being a good 
specimen of Neuropteris gigantea. (50, &c.) In six specimens 
pinnules of Neuropteris, with other vegetable remains, are 
more or less clearly indicated. (144.) One haematite fragment 
contains apparently, besides pinnules of Neuropteris, leaves of 
a (?) sigillarian plant; this, if I rightly understand the label, 
comes from the same block as (145), which is a very 
fine-grained, reddish sandstone, from Overseal, with probably 
infiltration bands of secondary origin. It contains traces of 
organisms, possibly plant stems, around which some haematite 
seems concentrated. (146.) Another fine-grained sandstone, 
from a well at Gosty Lees, Overseal, exhibits traces of 
Stigmaria. (117.) One red sandstone, or conglomerate, a 
specimen of the breccia from Oaktliorpe, includes, apparently, 
a crinoid stem. (148.) In a fragment of cherty limestone, 
from Overseal, is a specimen of a lamellibranch (? Nucula 
luciniformis), with a second, ill-preserved bivalve and some other
