wished to have educated in Spain : the collec- 

 tions, the child, and the young ecclesiastic, 

 were all buried in the waves # . 



South-east of Nueva Barcelona, at the dis- 

 tance of two leagues, rises a lofty chain of 

 mountains, abutting on the Cerro del Berg an- 

 tin, which is visible at Cum an a. This spot 

 is known by the name of the hot waters (aguas 

 calientes). When I felt my health sufficiently 

 restored, we made an excursion thither on a 

 cool and misty morning. The waters, loaded 

 with sulphuretted hydrogen, issue from a quart- 

 zous sandstone, lying on the same compact 

 limestone, which we had examined at the Mcrro. 

 We again found in this limestone intercalated 

 beds of black hornstein, passing into kieselschie- 

 fer. It is not however a transition rock ; it 

 rather approaches, by it's position, it's division 

 into small strata, it's whiteness, and it's dull 

 and conchoidal fractures, (with very flattened 

 cavities) the limestone of Jura. The real kie- 

 sehchiefer and Lydian stone have not been 

 observed hitherto except in the transition slates 

 and limestones. Is the sandstone, from which 

 the springs of the Bergantin issue, of the same 

 formation as the sandstone which we describ- 

 ed -f at the Impossible and at Tumiriquiri ?
