_What we have performed thus far, lieth, for the most part, open to the use and improvement of all men. Only in some places, and chiefly in the Third Chapter, we have taken in the help of Glasses; wherein, after we had finished the whole Composure, some Observations made by that Ingenious and Learned Person Mr. ~Hook~, a Worthy Member of the ~Royal Society~, my much Honoured Friend, and by him communicated to me, were super-added: As likewise some others also ~Microscopical~, of my own, which his gave me the occasion of making._ _Those that shall think fit to examine, as well as to peruse these Observations, we advertise them, ~First~, That they begin, and so proceed till they end again, with the Seed: For they will hardly be able to avoid Errour and Misapprehension, if either partial or preposterous in their Enquiries. ~Next~, That they confine not their Enquiries to one time of the Year; but to make them in several Seasons, wherein the Parts of a ~Vegetable~ may be seen in their several Estates. ~And then~, That they neglect not the comparative ~Anatomy~; for as some things are better seen in one estate, so in one ~Vegetable~, than another._ _What, upon Observation already made, we have erected, as they are not Sticks and Straws; so neither do we assure all to be of the best Oak. How Dogmatical soever my Assertions may seem to be, yet do I not affect the unreasonable Tyranny of obtruding upon the Faith of any. He that speaketh Reason, may be rather satisfied, in being understood, than believed._ THE CONTENTS CHAP. 1. _Of the Seed as Vegetating._ The Method propounded. 1, 2. The _Garden-Bean_ dissected. 2.
