The fissures are in Lower Permian Limestone on the N.E. border of 

 Derbyshire. The chief fissure, known as " Pin-hole," is described. It 

 runs 40 or 50 yards into the hill-side. Below the surface soil in the 

 cavern, which contains recent pottery and bones, there is about 3 feet 

 of red sand, with blocks of limestone and pebbles. Bones were found 

 throughout this bed, but were especially abundant at the bottom. Below 

 this comes sand, sometimes cemented into a solid mass. No bones have 

 been found here ; the bottom of the fissure has not been reached. The 

 cave has probably been a hyaena-den ; but the bones seem to have been 

 rearranged by water. The bones include parts of Hyaena, Rhinoceros, 

 Elephas, &c. ; many have been gnawed by Hysenas. There is a barrier 

 of rock about 40 yards from the entrance ; very few bones have been 

 found beyond this, which makes it unlikely that they were carried into 

 the fissure from behind. W. T. 



Molyneux, William. The Trentham Gravel Beds. K Staff. Field 

 Club Palmers, pp. 103-110. 



The section in Trentham Park is in the middle or conglomerate 

 division of the New Bed Sandstone, and shows about 100 feet of coarse 

 consolidated gravel, with bands of pebbly sandstone. The pebbles of 

 this gravel are waterworn and rounded, and they consist of a variety 

 of siliceous rocks, syenite, limestone, &c. On most pebbles there are 

 curious spots, believed to have been caused by pressure or grinding 

 action. "VV. W.

Montgomery, R. A. On the Isle of Unst. Trans. Clifton Coll. Sci. 

 Soc. vol. ii. pt. i. pp. 83-102; 2 plates (maps) and 1 section. 



A sketch of the physical features of this, the most northern of the 

 Shetland Islands, and of the relations of these to its geological structure, 

 is followed by a description of the several rock-masses which compose 

 it. These are gneiss, mica-, talc-, and chlorite-schists, crystalline 

 limestone, and serpentine rock with euphotide. The limestone runs in 

 a narrow band about halfway along the island, dipping E.S.E. 60° to 

 70°. No fossils have been round in it. An account of the distribution 

 of the minerals of the island " is given. The paper concludes with 

 botanical, zoological, and archaeological notices, and some notes of 

 excursions. The plates are : — a coloured geological map, a map 

 " showing the position of certain minerals," and a section across the 

 island from E. to W. J. W. J.
