Aquatic Animals . 317 
had the Pleafure of finding three different 
minute aquatic Animals, which I had never 
before obferved. 
The firft of thefe feemed to the naked Eye 
like a very fmall and flender Worm, of a- 
bout one Third of an Inch in Length : but 
the Microfcope foon fhewed its real Form, 
and the Singularity of its feveral Parts, in 
the Manner they are reprefented Plate XII.

From the Fore-part of the Head of this 
Animal a long Probofcls, Horn , or Snout was 
extended, moving itfelf every Way with 
great Readinefs, and iftuing from that Part 
of the Head where the Mouth fhould be ; 
which anterior Part changed its Appear¬ 
ance according to the Motions of the Inftru- 
ment, fometimes extending itfelf and becom¬ 
ing more flender, and at other Times fhorten- 
ing itfelf and growing thicker. About the 
Head it had fomewhat of a yellowifh Colour, 
but all the reft of it was throughout per¬ 
fectly colourlefs and tranfparent, except the 
Inteftines, which w T ere confiderably opake, 
and difpofed as in the Picture. In them al« 
fo a periftaltic or internal Motion was dif- 
tindtly vifible. Along its Sides were feveral 
Papillce with long Hairs growing from them: 
its Tail ended very bluntly: it had two black 
Eyes, and was extremely nimble. 
I found only this fingle Animal of its 
Kind, from which I drew up the above Re* 
marks
