200 A JOURNEY IN BRAZIL.

 and drying fish, which is one of the great articles of 

 commerce here. This morning we have passed several 

 hours off the town of Ega, or Teff^ as the Brazilians 

 call it. It takes its name from the river Teffe, but the

 idea of continuing, in person, his study of the fishes in 

 the upper Amazons, leaving only some parties to make 

 collections, and going himself into Peru, to visit at least

 taining whether any vestiges of glaciers are to be found 

 in the valleys, and also of making a collection of fishes 

 from the mountain streams ; or should he renounce the

 somewhere in this region for the next month or two, com 

 plete, as far as may be, his investigation of the distribution 

 and development of fishes in the Solimoens ? Had the
