gentlemen of the faculty can beft inform us, whe-

 deration : , 



Why is the Rot fatal to (heep, hares, and rab- 

 bits, (and fometimes to calves,) when cattle of 

 greater bulk, which probably take the fame food, 

 cfcape uninjured ? 



Is the digeftive matter in the ftomach of thefe 

 different from that of the others, and fuch as will 

 turn the ova into a (late of corruption ; or rather, 

 are not the fecretory du6ls in the liver large enough 

 to let them pafs through, and be carried on in the 

 xjfual current of the blood ? 



. It ieems to be an acknowledged faft, that falt- 

 marflies never rot. Salt is pernicious to moft in- 

 fedls. They never infeft gardens where fea-weed 

 is laid.* Common fait and water is a powerful ex^ 

 pellent of worms bred in the human body.

 abound with anmialculsc oi various fpcclct*
