H. Rosenbusch. North of England generally. 



Mikroskopische Physiographic der Massigen Gesteine, 2nd ed. [this 

 new edition of a much-valued standard work on the microscopical study of 

 rocks is almost entirely re-written, and contains much new matter ; among 

 North of England rocks we notice references to and descriptions of the 

 following (the nomenclature being that adopted by the author) : augite-granitite 

 of the Cheviots ; chiastolite-slate around the Skiddaw granite ; diabases 

 [dolerites] of Westmorland, with the leucophyre of Swirrel Edge ; salite- 

 diabase of the Whin Sill [enstatite-dolerite, Teall] ; hornblende-picrite of 

 Little Knott [Bonney] ; augite-minettes and kersantites of the Kendal and 

 Sedbergh district [Bonney and Houghton] ; granophyres of Armboth dyke 

 and Mosedale, the latter with augite ; porphyrites of the Cheviots [including 

 Teall's hypersthene-andesites] ; labrador-porphyrites near Penrith, Eycott 

 Hill, Alston, and Langley Ford (Cheviots) [dolerites] ; tholeiite dykes of 

 Hett, Hebburn, Tynemouth, and Morpeth, the last being an olivine-tholeiite ; 

 and the olivine-free basalt of the Cleveland dyke [augite-andesite of Teall]].

of the rise and progress of the Hrematite Iron industry]. Trans. Cumb. and 



Westm. Assoc, part x (1884-85, pub. 1885), pp. 99-108 and litho. map.

Henry Stolterfoth. West Yorkshire. 



Microscopic Examination of Crummach Lake Deposit [contains about 

 95 per cent, of Carbonate of Lime, which was dissolved out with hydrochloric 

 acid ; the remainder was treated for diatoms, with result nil ; it consisted, 

 on examination by the microscope without chemical treatment, of fragments 

 of freshwater shells and tine amorphous grains of limestone]. Nat., Oct. 

 1884, p. 66. 



A. Strahan. Derbyshire. 



On Explosive Slickensides [in the lead-mines of Derbyshire some slicken- 



sided veins fly into fragments with violence when touched by the miner's pick ;
