in the gneiss-granite of the Cordillera of the 

 shore ; it may even be affirmed, that the inverse 

 direction (from S. E. to N. W.) often bears 

 with it the inclination towards the S. W. 



As that part of the groupe of the Sierra Pa- 

 rime which I passed over, contains much more 

 granite* than gneiss, and other rocks distinctly 

 stratified, the direction of the layers could be 

 observed in this groupe only on a small number 

 of points ; but I was often struck in this region 

 with the constancy of the phenomenon of loxo- 

 dromism. The amphibolic slates of Angos- 

 tura run N. 45° E. like the gneiss of Gua- 

 pasoso (Vol. v, p. 224), which form the bed of 

 the Atabapo, and like the micaslate of the pe- 

 ninsula of Araya, although there is a distance 

 of 160 leagues between the limits of those 

 rocks. 



The direction of the strata, of which we have 

 just related the prodigious uniformity, is not 

 entirely parallel with the longitudinal axes of 

 the two chains of the shore, and of Pari me -f . 

 The strata generally cut the former of those 

 chains under an angle of 35°, and their inclina- 



* The granite of Baraguan only, is at the same time 

 stratified, and crossed by veins of granite ; the direction of 

 the beds is N. 20° W. (Vol. iv, p. 504.)
