Nourifhment is wanting to produce Leaves, Shoots 
“ and Fruit; and fome inch thin leafy • Expan (ion is 
“ fo neceflary for this purpofe, that Nature provides 
“ fmall thin Expanfions, which may be called prima- 
“ mary Leaves that ferve to proted, and draw Nou- 
“ rifliment to the young Shoot and Leaf-buds before 
“ the Leaf it felf is expanded. 
“ And herein we fee the admirable Contrivance of 
“ the Author of Nature, in adapting her diffb'ent 
“ Ways of conveying Nourifliment to the different 
“ Circurnffances of her Produdlions. For in this ' 
“ Iryo-flatG of the Buds a fuitaJble provifion is made 
“ to bring Nouriihment to them in a Quantity fuffici- 
ent for their then fraall Demands. But when they 
“ are in fome degree increafed and formed, a much 
“ greater quantity of Nourifliment is neceffary in pro- 
“ portion to their greater Jnereafe : Nature, that flie 
“ may then no longer fupply with a fcanty hand, im- 
“ mediately changes her Method, in order to convey 
“ Nouriihment with a more liberal hand to her Pro- 
“ dudions; which Supply daily increafes by thegrea- 
“ ter Expanffon of the Leaves, and confequently the 
‘‘ more plentiful Aitradion and Supply of Sap, as the 
‘‘ greater growth and demand of it increafes. We find 
a much more elaborate and beautiful Apparatus for 
‘‘ the like purpofe, in the curious Expanfions of Blof- 
foms and t lowers, which feem to be appointed by
