98 FOSSILIFEROUS HAEMATITE NODULES IN LEICESTERSHIRE. 
Ctli.—The agate-like specimens are a study in themselves, 
and afford one of the most interesting examples it is possible 
to have of the delicately beautiful processes of mineralogical 
construction. 
7tli.—The magnetic properties displayed are not unworthy 
of investigation. 
8tln—The author having had the good fortune to discover 
in these haematite fragments the remains of some exceedingly 
rare organic fossil remains (Arthropoda) hitherto almost 
unknown* in the district, it should stimulate us to still 
further work amongst them. 
9tli.—Certain of these specimens probably possess as 
interesting a history, and would furnish enquiring minds with 
subjects for almost endless investigation as valuable in a 
mineralogical point of view as any it would almost anywhere be 
possible to obtain. In other words, I maintain that the number 
of points or characteristics possessed by the “ pebbles,” 
viz. :—Origin,—removal at close of the Carboniferous period, 
—treatment in Permian times,—re-deposition,—chemical 
change,—magnetic properties,—concretionary agate-like and 
other structure,—stride, and other super-induced features,— 
organic remains,—variety of structure, fracture, colour, &c., 
—occurrence in the alluvium,—value,—and so on,—is 
probably as great and as varied as it would be the lot of 
few to study in any other geological specimens. 
Lastly.—The author is indebted to several geologists and 
others who have kindly furnished him with ideas and inform¬ 
ation, enabling him to work out, so far as has been possible, 
the probable history of these burnishing pebbles.
