The PREFACE. 
And 1 hope the publication of this Specimen 
of what I have hitherto done^ will put others 
upon the fame purfuitSy there being in fo large 
a field y and among fuch an innumerable variety 
of fiiihjeElsy abundant room for many heads 
and hands to be employed in the work : For 
the wonderful and fecret operations of Nature 
are fo involved and intricatCyfo far out of the 
reach of our fenfeSy as they prefent themfelves 
to us in their natural ordery that it is im- 
poffible for the mofi fagacious and penetrating 
genius to pry into themy unlefs he will be at 
the pains of analjdng Nature y by a numerous 
and regular feries of Experiments 5 which are 
the only folid foundation whence we may rea- 
fonably exp'eSi to make any advancCy in the 
real knowledge of the nature of things. 
1 mufl not omit here publickly to acknowledgCy 
that I have in fever al refpe£is been much ob* 
liged to my ingenious and learned neighbour 
and friend Robert Mathers of the Middle'' 
Temple, Efqy for his affifiance herein.
