THE GEOLOGIST. 



The quartz of this province, and nearly all the rivers, are aurife- 

 ferons. A gold mine in quartz, drowned by water, lay abandoned 

 for a long time, until a Spanish company tried to make it accessible 

 by driving a gallery, but this project was abandoned in consequence 

 of heavy losses. 



Excellent iron, worked in a very primitive way, is found in the 

 province of Bulacon (north of Manilla). Fine magnetic iron- ore 

 occurs also. Grey sulphuret of copper is exploited in the northern 

 part of Luzon, both by natives (who bring the metal to the coast 

 in small shapeless cakes), and by a Spanish company. Native 

 mercury not associated with cinnabar, occurs in black magnetic 

 iron-sand at Albay (East Luzon). Coal exists in the inaccessible 

 localities of North Carnarines, and in the Isle of Leba, north of 

 Mindanao. Platinum is said to occur in a brook coming from the hill 

 of St Mablo, near Manilla. A Spanish company exploiting the copper 

 occurring in rolled pebbles on the Isle of Samar (south-east of Luzon), 

 could not cover their expenses. As to the red ehromate of lead, it 

 had been discovered by Don Isidro de Baaranda, of Madrid, who 

 brought to England the finest specimens of this mineral. Its scarcity 

 is accounted for by the circumstance that the natives near the Leba 

 gather the small crystals of it and crush them to powder, to strew 

 over newly written letters. 



New Fossils from Radoboy and Trieste. 



Remains of Deljphmojpsis Freyeri have been found in the Tertiary 

 beds of Radoboj (Croatia)— so well known for their abundance of 

 fossil plants and insects. A tooth of a Rhinoceros, different from 

 Rh. tichorhinus, and resembling the Rh. Mercldi, from Daxland, near 

 Carlsruhe, has been found in a cave recently discovered near Matterie, 

 two Austrian miles from Trieste. 

 Stoliczker on the Fossil Molusca of the Hierlatry {Middle Lias) Strata. 



Among the seventy-two species of moluscs (fifty-four Gasteropoda 

 and eighteen Acephala), occurring in these beds of the east Alpine 

 region, eighteen are identical with the forms known from the middle 

 Lias of Fontaine-Elonpefour, and the Chalons- sur-Saone (Normandy), 

 eighteen with German forms, and forty-eight species have not been 

 described Six species only occur simultaneously in the German, 

 Alpine, and French Lias; some of them are also known to occur in 

 the coeval strata of England. 



Secondary Rocks of Portugal. 



Prof. E. Suess, on examining a large collection of fossil Brachiopo da 

 from 1VH ugiil, lias arrived' at the conclusion that the marine fauna 

 of the secondary rocks in Portugal bear a far greater resemblance to 

 the corresponding faunae of North-Eastern Europe than to that of 

 Souili Kurope. 



M. Foctterlie on the Brown Coal of Zovenceclo (Nicentine). 

 This coal is embedded in the "basaltic tuff of the Monti Beridi, overly- 

 ing a small surface of the Eocene Tertiaries. Two coal-seams from 

 three and a half to seven feet in thickness, are at present open; both
