Beginning to unfold fome of theni , Mr. Wray immediately 
judged them to fae made up of pieces of Rofe leaves, and 
called to mind, that this very Spring a worthy friend of his, 
yix.Francis 'jejfof :, brought him a Rofc-leaf, out of which 
himfelf faw a Bee bite fuch a piece, and fly away with it in 
her mouth. Whereupon fearching the Rofe-trees there-
