'T^HE Animals of this Clafs are of flow motion, foft fiibftance 
A able to increafe their bulk and reitore parts which have been 
d Itroy^d, extremely tenacious of life, and the inhabitants of moift 
places. Many of them are without diftina head, and moft of them 
wnboiit /«/, They are principally dillinguilhed by their untacula 
gr feelers 
fjy the Ancients^ they were not improperly called imperfea ani- 
ma *, as being deftitute of ears, wfe, head, eyes and legs ; and arc 
therefore totally diftina from Infeas. 
They are divided in to five' Orders. 
I. INTESTINA. Are of a formation the moft Ample, and 
live, fome of them within other animals, 
feme in waters, and a few in the earth. 
The Gordius perforates clay to give a pas* 
fage to fprings and water; the Lumbritus 
pierces the earth, that it may be expofed 
to the aaion of the air and moilhire : in 
like manner, the Teredo penetrates wood, 
and the Phloas and Mytilus rocks, to efteft 
their dilfolution. • 
II. MOLLUSCA. Are naked, furniflied with tentacula or 
arms, for the molt part inhabitants of the 
• fea ; and by their phofphoreoiis quality, 
illuminate the dark abyfs of waters, re! 
fieiling their lights' to the firmament Thus 
what is beneath the water correfponds 
with that which is above.
