On an Immense Flight of Small Bulterjlles [Terias Lisa) in

Marvellous indeed, as naturalists well know, are those 

 periodic movements of the feathered race known as spring 

 and autumn migrations. Moved by an instinctive impulse 

 implanted in them by the Creator, thousands upon thousands

 ming bird, travel by sea or land to distances so remote that, 

 unless it was ascertained beyond doubt that the space was 

 traversed, the fact would be considered aluiosi incredible. 



But if we are greatly astonished at the power of endurance 

 exemplified in this long-sustained flight of some of the 

 smallest birds, what will be said when we relate a circum- 

 stance connected with a similar power possessed by a species 

 of butterfly, so small and apparently incapable of with- 

 standing the violence of the elements, that we know not 

 which is the more remarkable, the distance traversed, or the

Thus it was. Early in the morning of the first day of 

 October, in the year 1874, several persons living on the north
