Tropical Flowers, p. 292. — "During twelve years spent amid the grandest 

 tropical vegetation, I have seen nothing comparable to the effect produced on 

 our landscapes by gorse, broom, heather, wild hyacinths, hawthorns, purple 

 orchises, and buttercups."— Wallace's Malay Archipelago. 



Coca-plant, p. 293. — The engraving conveys the impression that the leaves 

 are parallel-veined ; but the coca is a dicotyledon, with the under surface of 

 the leaf strongly marked with veins, of which two, in addition to the midrib, 

 run parallel with the margin. 



Fedrero, Map. — This town on the Rio Negro is also written Pedreira.
