feme root; and what is dill more, found and fmutty 

 grains, at the fame time in one and the fame ear. To 

 imitate our objedors, then, and attempt to obviate 

 one difficulty by darting another; will they permit 

 me to afk what they can fay to this ? If fmutty feed 

 infallibly produces a fmutty crop, as they maintain, 

 what produces the found ears which grow out of 

 the fame root with the fmutty ears, and the found 

 grains which are found in the fame ear with the 

 fmut-balls ? 



This fingle obfervation clearly refutes their whple 

 argument. It is an eftablifhed maxim in phyficks, 

 *^ that the fame caujes infallibly produce the fame 

 " effeSiSi' and were it not fo, human knowledge of 

 any future event would be an impolfible thing; for 

 this is the principle which directs adions to ends ; 

 without it, intention or defign would have no obje6l. 

 To fay then that both found and fmutty grain proceed 

 from the fame root, which root is vitiated and de- 

 praved, yet is the efficient caufe of both, is as pal- 

 pable a contradiftion as to aflert, that good whole- 

 fome blood, and a putrid, malignant, poifonous 

 ichor, may be taken from the fame vein at one 

 and the fame moment.* 



• A friend of Mr. Wirapey's, on reading this remark, obfervcs, 

 that even tliis may be poflible. The ftrcam of the lame moment 

 may contain good and highly contaminated particles.
