The Epiftle Dedicatory. 





























fon of that eminent and happy Worth, which, as it was 
too good,to fear envy ; fo 1s it too great, to need an Elogie. 
With Him, it was, You were pleafed to commit to Me, 
the further profecution of this Work ; the Beginnings 
whereof, were by Your Order formerly made publique. 
Had I confulted my own Abilities altogether, I fhould 
{carcely have ventured upon it; feeing very little, for 
which I could think well of my felf, faving, That T had 
learned, upon good grounds, to think of You with greateft 
Honour. But I alfo confidered, That to infift hereon too’ 
much,might be a reflection upon Your Judgments,who had 
thought fit to make choice of Me. And, That Yow were 
not more the Patrons of Wit, than of Induftry ; and of 
All, who hall endeavour to find out, or to confirm the 
Truth of Things. Withal, I looked upon Nature, asa Trea- 
fure fo infinitely full; that as all Men together, cannot ex- 
hauft it ; fono Man, but may find out fomewhat therein, 
"af he be refolved to Try. 
In compliance therefore with Your Commands, I have 
hereunto devoted a very confiderable part of my Time. 
Thefe,adding force to my own Defires,of being fomewhat 
inftrumental to the Improvement of Medicinal, and other 
wholefom Knowledge: if peradventure, as we increafe 
herein, we may become better, and more happy. As to 
which Improvement, though I could not hope; yet, I 
would not difpair. I have already prepared the Soil, and 
made fome Plantation ; what remaineth behind, and the 
Vintage of the whole, will depend much upon the con- 
tinued Influence of Your Beams: for how unpromifing 
foever the Stock may be; yet the Fruit cannot but be 
fomewhat matured, upon which You are pleafed to thine. 
I am alfo confident, that the fame Nobilty and Goodnefs, 
which accept the endeavours, will likewife pardon the 
faults, of 
My Lord,
