it with the eye of reason, you shall see a reason for everything that is written, whereby you may find the very ground and foundation of Physic; you may know what you do, and wherefore you do it; and this shall call me Father, it being (that I know of) never done in the world before.

I have now but two things to write, and then I have done.

1. What the profit and benefit of this Work is
.
2. Instructions in the use of it
.

The profit and benefit arising from it, or that may occur to a wise man from it are many; so many that should I sum up all the particulars, my Epistle would be as big as my Book; I shall quote some few general heads.

First. The admirable Harmony of the Creation is herein seen, in the influence of Stars upon Herbs and the Body of Man, how one part of the Creation is subservient to another, and all for the use of Man, whereby the infinite power and wisdom of God in the creation appear; and if I do not admire at the simplicity of the Ranters, never trust me; who but viewing the Creation can hold such a sottish opinion, as that it was from eternity, when the mysteries of it are so clear to every eye? but that Scripture shall be verified to them, Rom. i. 20: ``The invisible things of him from the Creation of the World are clearly seen, being understood by the things that are made, even his Eternal Power and Godhead; so that they are without excuse.''--And a Poet could teach them a better lesson:

``Because out of thy thoughts God shall not pass,
His image stamped is on every grass.''

This indeed is true, God has stamped his image on every creature, and therefore the abuse of the creature is a great sin; but how much the more do the wisdom and excellency of God appear, if we consider the harmony of the harmony of the Creation in the virtue and operation of every Herb!

Secondly, Hereby you may know what infinite knowledge Adam had in his innocence, that by looking upon a creature, he was able to give it a name according to its nature; and by knowing that, thou mayest know how great thy fall was and be humbled for it even in this respect, because hereby thou art so ignorant.

Thirdly, Here is the right way for thee to began at the study of Physic, if thou art minded to begin at the right end, for here thou hast the reason of the whole art. I wrote before in certain Astrological lectures, which I read, and printed, intituled, Astrological Judgment of Diseases, what planet caused (as a second cause) every disease, how it might be found out what planet caused it; here thou hast what planet cures it by Sympathy and Antipathy; and this brings me to my last promise, viz.

Instructions for the right use of the book.

And herein let me premise a word or two. The Herbs, Plants, &c. are now in the book appropriated to their proper planets. Therefore,

First, Consider what planet causeth the disease; that thou mayest find it in my aforesaid Judgment of Diseases.

Secondly, Consider what part of the body is afflicted by the disease, and whether it lies in the flesh, or blood, or bones, or ventricles.

Thirdly, Consider by what planet the afflicted part of the body is governed: that my Judgment of Diseases will inform you also.
