" 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, Flozver, 

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

 joyn the Microscope', and to examine all 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.
