The fecond fpecies of pafle eel is oviparous. It is eafily 

 diflinguifhed from the firft kind, by being much fmaller ; it is 

 reprefented at Fig. 8. Tne conformation of the alimentary duel 

 and the interlines are in general nearly the fame, though an intel- 

 ligent obferver will find out fome fpecific differences. By 

 the flexion of the interlines c c c, a void fpace is left a little be- 

 yond the middle of the body, where the eggs are collected. 

 There is no exterior protuberance near the ovary, as in the pre- 

 ceding one, but a fm all hole, I, may be difcovered, near which are 

 placed two little tubercles f f, though they are very feldom to be 

 obferved without comprefling the animalcula. 



We meet with another eel in pafle, which may with reafon be 

 called the common eeh It is often to be found in grains placed 

 in the earth, in which the germ is deflroyed, in the roots and 

 Items of farinaceous plants, in the tremella of Adanfbn, and in 

 feveral fpecies of conferva, as well as in feveral infufions. This 

 eel, when at it's full growth, is rather longer than the common 

 eel of blighted wheat ; one of them is reprefented at Fig. 11. 

 They are eafily diftinguifhed from the eels of blighted wheat, be- 

 caufe they have no ranges of globules like it, by the two little 

 protuberances which are near the middle of the body, and by the 

 regular diminution of the tail. It is oviparous.. 



A very fmall fpecies, reprefented at Fig. 9, may alfo be found 

 in pafle; they may be diftinguifhed from the young eels of the 

 larger fort by their vivacity and ilendernefs.
