OrchiUa, page 29. — This valuable lichen comes chiefly from Tumbez. It 

 is not found on the rocks, like the orchilla of the Old World, but grows on 

 various trees. The foliage of a tree disajjpears Avhen the orchilla commences. 

 The sea air is indispensable to its production, as it is found only near the 

 coast. 



Religious Intolerance^ p. 91. — The expression " Protestant dogs" has since 

 been publicly repeated by a priest in a sermon, Avho told the people to con- 

 fess, or they would be treated in a similar way. It called forth a remon- 

 strance from Mr. Hamilton, the British Minister, directed to the archbishop, 

 declaring such conduct inhuman and unchristian. The Pope's Nuncio left 

 Quito for good in July, 1869. 



Fish in the Quito Valley, p. 107. — Dr. Gill informs me that the true name 

 of this little fish is Cyclopium Humboldtii, Swainson. It belongs to the sub- 

 family Trachelypterinas, under Siluridre. 



Hummers' Nests, p. 108. — They are not always of a lengthened form, as 

 the text Avould imply, but are sometimes quite shallow. They are invariably 

 lined with the softest vegetable materials and covered with moss. The nests 

 are not as compact as those of our Northern hummer, and, so far as we ob- 

 served, are never shingled with flat lichens. 



Humboldt in 1802, p. 156. — He spent five months in the valley of Quito. 



Febas Fossils, p. 282. — In a letter to the author, Mr. Darwin says : " Your 

 discovery of marine shells high up the Amazon possesses extreme interest, 

 not only in itself, but as one more most striking instance how rash it is to as- 

 sert that any deposit is not a marine formation because it does not contain 

 fossils. As for myself, I never believed for a moment in Agassiz's idea of 

 the origin of the Amazonian formation." Agassiz " candidly confesses (Ly- 

 ell's Principles, i., 468) that he failed to discover any of those proofs which 

 we are accustomed to regard, even in temperate latitudes, as essential for the 

 establishment of the former existence of glaciers where they are now no more. 

 No glaciated pebbles, or far-transported angular blocks with polished and 

 striated sides ; no extensive surface of rock, smooth, and traversed by rectil- 

 inear furrows, were observed. " The fossiliferous bed at Pebas is as plainly in 

 situ as the Medina sandstone at Genesee Falls.
