Of the frejh Water Polype, 
of the mouth, as a£ a b, %. 4.14* Sometimes the polype 
is entirely turned at firft, and then it covers the end of 
the briftle a b, fig. 413. In this cafe the exterior fuper- 
ficies of the polype is become the interior, which now 
touches- the hog’s briftle; however it feldom happens that 
the polype is entirely turned, but moil commonly the tail 
part a b is out of the mouth b, fig. 414. and at the fame 
time a part thereof is not turned 5 that is, its anterior 
end a c, which being terminated by the arms, is folded 
over the turned end. Then to finifh the turning, take 
an hair pencil in your right hand, and the end of the 
hog’s briftle in the left. Always holding the other end 
&f the briftle together, with the polype in the water, and 
ftroke the end a c, which is not turned, very foftly with 
the hair pencil, that way which is neceflary to turn it, 
that Is to fay, from a to c, fig. 414. which is prefently 
performed, at which time it appears as at a b, fig. 413. 
Then holding it in the water, pufh it from a to b, with 
the point of an hair pencil, and it will fall to the bottom 
of the glafs without being put out of order. 
When it is firft turned, the mouth clofes, and the lips 
a, incline a little inwards ; the arms a c appear to join 
in a bundle, and to come out of the middle of the po¬ 
lype’s- mouth, as at a, fig. 415* 
After the polype is turned, extend it as much as pof- 
lible with the hair pencil, then taking an hog’s briftle 
with a knot near one end thereof, run the other end 
through the polype’s body, near its lips ; at that inftant 
let the other end of the briftle e, drop into the water, 
and with the point of the pencil, pufh the polype to the 
middle a, of the briftle, fig. 416. then take out the briftle 
and polype, and put them into a glafs, f, e, g, h, taking 
care that it only touches the glafs by its two extremities 
c and d, that the polype may be a great way from the 
bottom
