" If then the Anatomy of Vegetables be so useful a Mean, we ought 

 not to streighten it ; but to force this, as well as the rest, to its utmost 

 Extent. And therefore, first of' all, To go through all the Parts, 

 with equal care; examining the Root, Trunk, Branch, Leaf, Flower, 

 Fruit, and Seed. . . . Together with the Knife it will be necessary to 

 joyn the Microscope; and to examine aU the Parts, and every Way, 

 in the use of That. As also, that both Immediate, and Micro- 

 scopical Inspections, be Compared: since it is certain. That some 

 things, may be demonstrated by Reason and the Eye conjunct, 

 without a Glass, which cannot be discovered by it." 



Nehemiah Grew, The Anatomy of Plants, 1682.
