44 three or four Clufters together, which re~ 
44 fembled exa&ly thofe of our common 
44 Caterpillars, or of the Silk-worm Cater- 
44 pillar. But the moft remarkable Thing 
44 in this Creature is a Kind of Horn or Feeler 
44 which it feems to carry in its Mouth, and 
44 may be juft feen by the naked Eye if 
44 your Water be clear. 'Tis in the larger 
44 ones about -Ar Inch long. This (I know 
44 not what to call it) it waves to and again 
44 as it moves in the Water, or when it 
44 creeps up the Side of the Glafs; which 
44 it does fomewhat like a young Leech, but 
44 without contracting its Body fo much, and 
44 rather in the Manner that Caterpillars do. 
44 I have not been able to learn, though 
44 I have viewed it a long Time together, 
44 whether it gets any Food with this Horn, 
44 nor can I find whether it be hollow: but 
44 I am certain ftis not pointed, but rather 
46 blunt : nor have I ever feen it contracted 
44 any thing confiderably.—I muft not omit 
44 to tell you, that ’tis a very tender Crea- 
44 ture; for in taking up the ftrft I viewed 
44 with a Quill, as we do the Polypes , by the 
44 Side of the Glafs, I injured it fo much, 
44 that it was nearly cut in two, and its 
44 Horn came off, after it had been a little 
44 while in the Drop of Water upon the 
44 Slip of Glafs. I was glad of this laft Ac- 
44 cident, as it gave me an Opportunity of 
44 obferving the Horn or Feeler in a better 
44 Manner
