vii The PREFACE. 



And 1 hope the publication of this Specimen 

 of what I have hitherto done, will pat others 

 upon the fame purfuits, there being info large 

 afield, and among fuch an innumerable variety 

 of fuhjetts, abundant room for many heads 

 and hands to be employed in the work : Hor 

 the wonderful and fecret operations of Nature 

 are fo involved and intricate, fo far out of the 

 reach of our fenfes, as they pre fent themfelves 

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

 foffihlefor the mofl fagacious and penetrating 

 genius to pry into them, unlefs he will be at 

 the pains of analyfing Nature, by a numerous 

 and regular feries of Experiments 5 which are 

 the only folid foundation whence we may rea- 

 fonably expeEl to make any advance, in the 

 real knowledge of the nature of things. 



Imuft not omit herepublickly to acknowledge », 

 that I have in fever al refpecis been much ob- 

 liged to my ingenious and learned neighbour 

 and friend Robert Mathers of the Middle 

 Temple, Efcp> for his ajjiflance herein.
