WORMS. 257 



midway between a very fmall earth worm and 

 a millepedes, or woodloufe, partaking of the 

 length of the former, and the feet of the 

 latter, extremely fharp, and exceedingly nu- 

 merous. Immediately after their ejedlion they 

 continue to writhe and twirl moft rapidly upon 

 the furface of the dung, bearing great affinity 

 to the action of an eel when taken from its 

 natural element and placed upon land. 



There is alfo fometimes feen adhering clofely 

 to the fame parts, and difcharged in the fame 

 manner, an indolent kind of bot, appearing 

 almoft inanimate, that keeps its hold only by a 

 point like the leeci, and is, in form, exadlly like 

 the griiiy qr worm, that may be fo plentifully 

 extradled (by prelTure only) from thofe promi- 

 nences perceptible upon the backs of horned 

 cattle during the hot months in the fummer 

 feafon. 



Thus much is introduced to prove the variety 

 of thofe infefts, in general fo prejudicial to the 

 fram.e when once they have gained admiffion, 

 or fecured their /eats : refpeding which fuch 

 adiverfity of opinions have been broached, and 

 nothing finally fatisfadory afcertained of their 

 origin, either in the human fpecies or brute 

 S creation.
