modem nations,— is distributed in the seeds, and de- 

 posited in the roots of vegetables ; while the milk 

 which we use as food appears exclusively the pro- 

 duct of animal organization. Such are the impres- 

 sions which we receive in early childhood, and such 

 is the source of the astonishment with which we 

 are seized on first seeing the cow-tree. Magmficent

 point at which the Rio Negro and the River of Ama- 

 zons communicate with the former stream. They 

 therefore returned to Guacara, to take leave ot the

 more on the shores of the Lake of Valencia. It
