 and falling to the floor, where it again begins to 

 search till it at last mounts my leg as I sit writing, 

 and appears upon my knee, furnishes a good sample 

 of blind, pushing Nature, radiating in all directions 

 in order to be sure to hit a mark that lies only in one 

 particular direction — in this case, a suitable place 

 or corner in which the insect may weave the shroud 

 in which it is to undergo its metamorphosis, and 

 emerge a winged creature.
