Jervis, G. I Tesori Sotterranei dell' Italia. [Title on p. 74.] 

 The continuation of a work the first volume of which (on the Region 

 of the Alps) was published previously, whilst the third (Sardinia and 

 Sicily) is yet to come. This part refers to the Region of the Apennines, 

 and to the active and extinct volcanoes connected therewith. 



Considerations on the physical and chemical changes of rocks and 

 minerals through chemical decomposition, pp. 3-7 ; list of the minerals 

 of the sedimentary rocks of the Apennines, pp. 9-13 ; detailed notice of 

 minerals, mineral waters, aerolites, mines, &c., in each province, pp. 33- 

 624 ; the stratified nature of serpentine explained at p. 143 ; sulphur 

 a stratified and not a volcanic product, p. 189 ; boracic-acid lagoons 

 not due to volcanic agency, but to decomposition of stratified rocks, 

 p. 430 ; "Vesuvius, pp. 587-607, chronology of its eruptions, its minerals, 

 and its gases. W. W. 



Cenni geologici suUe montagne poste in prossimita al 



giacimento di Antracite di Demonte. [Geological notes on the 



mountains adjacent to the Anthracite deposit of Demonte.] 8vo. 



Pp. 16. Translated, with additions, in Min. Journ. Aug. 7, 1875. 



The argillaceous and calcareous schists of Demonte are identified 



with the Gailthal beds, now for the first time discovered in the Western 



Alps, and belong truly to the Carboniferous formation ; thickness about 



1600 feet. Below are Serpentine and Euphotide rocks surmounted by 



talcose schists. The first coal is found 33 feet above the top of the 



talcose schists ; five beds are mentioned ; the distance between them 



varies from 23 to 115 feet; but their thickness is not given ; quality 



anthracitic. Coal could be won to a depth of 275 fathoms by levels, 



without any shaft. Above the Carboniferous shales are beds of white 



quartz, and then Palaeozoic limestones, 3300 feet thick. E. B. T. 



Kendall, J. D. The Haematite deposits of "Whitehaven and Furness. 

 Coll. Guard, vol. xxviii. pp. 157, 230, 374, plan and 18 figs, in text. 



Describes the deposits in detail. The Whitehaven haematite is 

 harder and more compact than that of Eurness. Gives sections of the 

 ore-bearing beds in each district, and analyses of the various qualities 

 of ore. Examines the theories which have been imagined to account 

 for the formation of the deposits, and dismisses that of the igneous 

 origin, believing that the haematite was originally deposited as car- 

 bonate, partly displacing the limestone, and partly in previously exist- 

 ing caverns. Thinks that the haematite is younger than the Carboni- 

 ferous Limestone, and older than a great part of the Permian.
