The PREFACE. 



And 1 hope the publication of this Specimen 

 of what I have hitherto done, will put others 

 upon the fame purfuits, there being info large 

 afield, and among fitch an innumerable variety 

 of fubjefis, 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 intricate, fo far out of the 

 reach ofourfenfes, as they prefent themfelves 

 to us in their natural order, that it is im- 

 foffiblefor the moft fugacious and penetrating 

 genius to pry into them, unlefs he will be at 

 the pains ofanaljfing Nature, by a numerous 

 and regular feries of Experiments ; which are 

 the only foiid foundation whence we may rea~ 

 finably expeB to make any advance, in the 

 real knowledge of the nature of things. 



Imufl not omit here publickly to acknowledge, 

 that I have in fever al refpecls been much ob- 

 liged to my ingenious and learned neighbour 

 and friend Robert Mathers of the Middle 

 Temple, Efq; for his affi fiance herein.
