xxviii. Heft 4, p. 777. 



Preliminary note on the deposition of ores in the Rammelsberg, near 



Goslar. It is held that they have been subsequently introduced, lenti- 



forra cavities being formed during movements of the beds, and liUed 



from solutions. E. B. T.

 toscana). [Miocene Lignites of the Massetano.] Boll. E. Com. 

 geol. Ital. vii. pp. 31-39. 

 In the Massa district the L. Miocene is absent ; the beds are either 

 Eocene or M. Miocene and upwards. The section in descending order 

 is : — Plastic clays with some lignite bands ; arenaceous clays and pud- 

 ding stones (marine) ; red conglomerates ; grey clay {MaUajone) ; bitu- 

 minous limestones with Dreissena Brardi ; two valuable lignite beds, 

 3-8 feet, which yield coke by burning ; Eocene rocks. E. B. T. 



U Poggio di Montieri (in provincia di Grosseto). [The Mon- 



tieri Hill.] Boll. R. Com. geol. Ital. vii. pp. 111-122, woodcut. 

 The hill of Montieri, 1050 m. above sea-level, was formerly worked 

 for silver, but abandoned since 1355. The hill consists of an arch of 

 alberese [Eocene], below which are nummulite beds, followed in 

 descending order by a conformable arenaceous series (probably Creta- 

 ceous) ; then come variegated clay-shales with fucoids, next a red lime- 

 stone, and then (only seen in mining-operations) the metalliferous 

 limestone, which is white, cryptocrystalline, and appears to be L. Lias. 

 Fresh headings are now being driven, which prove the hill to bo honey- 

 combed with the old workings ; enough rich argentiferous galena and 

 blende has been found to induce a prosecution of the research. The 

 ore occurs in a very irregular way, as it were cementing together blocks 

 of the white limestone, which is without bedding. E. B. T. 



Sul giacimento ofiolitico di llocca Sillana. [Ophiolitic Rocks 



of Rocca Sillnna.] Boll. R. Com. geol. Ital. vii. pp. 289-203. 



Describes the serpentine and associated rocks of Rocca Sillana at the 



extreme S.E. of the province of Pisa. The mass is wrapped round by the 



Pliocene, which reaches the height of 450 m. above sea-level. E. B. T.
