walking sometimes in the water, which was 

 shallow, sometimes between the torrent and a 

 wall of rocks, on a soil extremely slippery and

 northern forms seem also to appear in the ga- 

 lium caripense, the Valeriana scandens, and a 

 sanicle not unlike the s. marilandica. 



At the foot of the lofty mountain of Guacharo, 

 we were only four hundred steps from the ca-

 before the immense opening of the grotto. The 

 aspect of this spot is majestic even to the eye of
