164 ANIMALS KILLED iv. 
' The third fpecies of refurgent animals found in 
find confifts of certain minute eels, very like the 
anguillae 
very mintite, not one tenth of the fize of thofe men- 
tioned in the text, which, added to their rarity, was an ab- 
folute bar to experiment. They had no terminating pro- 
jeétions or hooks, nor were the different fafcia vifible, 
However, I fometimes thought two hooks of very few were 
perceptible, but I could never be certain. The animal was 
perfectly opaque, which prevented any obfervation of the 
interior part. There was no fand in the infufion, which had 
- been made of dried twigs eight or ten months before, and 
the floth’s natural abode was among the particles of mat- 
ter, efpecially on the twigs. How it propagates I am 
ignorant : it did not multiply much. 
I have difcovered another animal which moft probably 
belongs to this fingular clafs. It was in an infufion the 
fame as the former, and there I had it from the begin- 
ning of May until the end of Auguft. It then difappear- 
ed, and I faw one in the fubfequent February. In one 
other infufion, I found two or three nearly the fame. It 
bears the greateft refemblancc to a moft minute caterpillar, 
both in appearance and motion. It moves little, and then 
with great awkwardnefs and Janguor. The largeft might 
be about one-third of a line in length, and perceptible by 
the naked eye, which could only diftinguifh a long white 
fpeck, but few are of this fize. Inftead of fix legs and 
four hooks, there are eight legs, the two laft exactly 
like thofe of a caterpillar. With the fecond higheft mag- 
pifier of my microfcope, I could obferve each of the fir 
legs
