From this account ot the Food of the Death Watih^ I 
cannot forbear dlgrefling again, to note a common error 
' about the food cf fuch Creatures, as have been, or are 
thought to live upon things fcarce nutritive ot themfelves. 
Thus x\\G Chameleon was thought to live upon the Air, 
when Flies are eaten by him : Filbes to live upon Waterier 
at leaft to fatisfy a perpetual tbirft therewith ^ whereas 
their fucking Water is breathing, and their Food as little 
of Water perhaps, as other Creatures ufe. So Bartk^ 
Worr^/s doubtlefs eat Earth, but in all probability it is 
Earth made of rotted Roots, Plants, or fuch nutritive 
things, not pure Earth, Nay, fo neceflaryis good fub- 
ftantial Food to all Animals on this our Earth, that I am 
of opinion(from I think very goodReafon)that there is no 
Animal but what hath its proper Food, even the moft mi- 
nute Infeds whatfoever^ and that alfo none of the four 
Elements, although therewith mixed. Concerning which 
(to fave the^rouble of enlarging this digrcflion)an inftance 
of mine may be found of the Foodol Water- Animalcules^ 
which my very ingenious and learned FriendMrR^j^ hath 
thought fit to publifti this year in his late Edition of his 
excellent Book. Of the Wifdom of God manifefled in the 
Works of the Creation^ p. 49 1.
