The Natural History of Selborne

Tho’ white butterflies abound, & lay many eggs on the cabbages; yet thro’ over-heat, & want of moisture, they do not hatch and turn to palmers; but dry & shrivel to nothing.  One swift still frequents the eaves of the church; & moreover has, I discover, two young nearly fledged, which show their white chins at the mouth of the crevice.  This incident of so late a brood of swifts is an exception to the whole of my observations ever since I have bestowed any attention on that species of hirundines!
