tide, repose on the sandstone of the Llanos ; if 

 this superposition takes place, it must be found 

 in descending the table-land of Cocollar tow- 

 ards the Mesa of Am ana. On the southern 

 coast of the gulph of Cariaco, the limestone- 

 formation (Punta Delgada), probably covers, 

 without the interposition of another rock, the 

 micaslate that passes to carburated clayslate. 

 In the northern part of the gulph I saw dis- 

 tinctly this clayey formation at the depth of two 

 or three fathoms in the sea. The sub marine hot- 

 springs (Vol. Hi, p. 199) appeared to me to gush 

 from micaslate, like the petroleum of Maniquarez 

 (Vol. ii, p. 290). If any doubts remain as to the 

 rock on which the limestone of Cumanacoa is 

 immediately superposed, there is none respect- 

 ing the rocks which cover it, such as 1st. the 

 tertiary limestone of Cumana, near Punta Del- 

 gada, and at Cerro de Meapire (Vol. iii, p. 181); 

 2d. the sandstone of Quetepe and Turimiquiri, 

 which forming layers also in the limestone of 

 Cumanacao, belongs properly to the latter soil ; 

 the limestone of Caripe, which we have often 

 identified, in the course of this work, with ju- 

 rassic limestone, and of which we shall speak 

 in the following article. 



VIII. FORMATION OF COMPACT LIMESTONE OF CARIPE. 



In descending the Cuchilla of Guanaguana 

 towards the convent of Caripe, we find another
