EXCLUSION TO MAUHES AND ITS NEIGHBORHOOD. 315

 questions of the interpreter. 



Mr. Agassiz lias been very fortunate in collecting in this 

 region. Although we are at so short a distance from 

 Manaos, where he already knows the fishes tolerably well, 

 he finds a surprising number of new genera and species 

 about Mauhes and its neighborhood. As usual, wherever

 fin as a cure for a sick person, another had taken out an 

 eye as a love-charm, which, if it could be placed near the
