trifling with your time and patience to relate here, 



may not the reputation of the wholfomenefs or 



unwholfomenefs of butter, depend upon, or be ow- 

 ing to fome of the above caufes? And may not 

 many a cafual, nay, obftinate complaint originate 

 from the fame fource, which the phyfician may have 

 in vain laboured to account for ? Butter is found 

 very frequently to occafion much diforder to very 

 weakly, delicate, and irritable ftomachsj yet thefe 



ftomachs will bear olive oil: this cannot be 



therefore accounted for from the oleofe parts, but 

 may from the metallic impregnation. 



I will not contend, that all the ill effects attri- 

 buted to butter are caufed by the mineral particles 

 which it gains by the means above ftated. I only 

 infill that it is poflible, and indeed very probable, 

 and that it may in confequence do frequent mif- 

 chief; and that when butter is free from thefe par- 

 ticles, it is not fo unwholfome as fome have af- 

 fertedj though when it does contain them, it is 

 found to diforder very tender perfons. 



To enlarge upon the fubjecl, or attempt to ex- 

 plain the many ways and how a very fmall portion 

 of the above metals may prove injurious to the 

 human frame, in fome particular conftitutions, 

 will be only to repeat what has already been faid
