next day I found it in the Water entirely feparated from 
the body, and was about one third of the length of the 
Parent. The formation of the horns are well figured by Mr 
X. and they iflue (like radij) not from the extre^iity, but 
quite round a fmall knob^ which I take to be the Head- 
The Horns have a vermicular motion* and are extended 
or fhorten'd both altogetlier and feverally. The other end 
is flat at the extremity, and he often fix'd it (like a Leech) 
to the bottom or fide of the Glafs in which I kept him. 
He alfo contrafts and dilates his body at pleafure, and e- 
fpecially, when touch'd or difturb'd, will bring both Body 
and Horns into a Imall compaft, and has then the appearance 
of Fig. ^ , and 4. The Horns are perfeftly white, and the 
Body yellowifli, and to a naked Eye not eafily difcernable 
in the Water, it being when extended no thicker than a 
good Horfe-hair* 
The fmall Plant mention d in the fame TranfaS. is the 
Le/ts Pakjlris or Duck^meat , which floats plentifully on 
our Ponds or Ditches. But I muft diflent from Mr £• 
where he fays it does not come originally from the bottom, 
for I very well remember that many years finee, the late 
W. CL Efqs fliew'd me the manner of its fpringiog out of 
the Mud 0 and we often obfcrv'd, that when the Leaves were 
grown to a competent fize, the force of the Water eafily 
drew the minute fiKgle fibr'd Root, and rais'd the Plant to 
the furface. I own that the Leaves when floating do con- 
tinue to grow, and may be encreas'd after the manner he 
nientions^ and I have often taken the young Plant which he 
piftures out of them, fo that they may be called Seeds more 
properly than Leaves 3 and my opinion is, that toward the 
end of the year, upon their corruption, they Gnk to the 
bottom, and there take root, fo as to continue the fucjeiii- 
on. 
The Ammakiild v^hich Mr I. defcribcs (licking to the 
B.oot of the Plant. I have often obicrv'd, not only in VVa- 
ter Flams, but adhering to the bodies of many forts of 
Water
