SIR, 
I Take the Liberty to lay before you the 
bed: Account my Observations can at 
prefent furniffi out, concerning that won¬ 
derful Water Infedt the Wheel Animal, which 
you and feveral other of my curious Friends 
belonging to the Royal Society have often, 
done me the Honour to examine by my 
Glaffes, and admire along with me : and as 
it is extremely difficult to convey by Words 
only any true Idea of a Creature fo very ex¬ 
traordinary, I have added exadt Drawings 
pf its different Forms, Poftures, and Ap¬ 
pearances ; in Hope, by that Means, of be¬ 
ing underftood by thofe who have never 
Seen the Subject, as well as approved of by 
thofe that have: in cafe you ffiall judge thefe 
Lines worthy to appear where you prefide. 
This wonderful little Infedt is found iq. 
Rain Water, that has hood fome Days in 
Leaden Gutters, or in Hollows of Lead on 
the Tops of Houfes, or in the Slime or Se~ 
diment
