204 Of the frejh Water Polype. 
A polype partly turn’d back again, remains but a little 
while in that fituation, as at fig. 406. The place a, to 
which this return’d portion a c, was fixed to the other 
part a b of the body, became a little ftreighten’d, and 
the portion a c, formed a right angle therewith, as is 
ihewn at fig. 408. where a c reprefents the returned por¬ 
tion, and a b the other part of the body; the fame day 
another head appear’d at e, and .federal arms began to 
fhoot, on one fide a o, of one mouth, a o n, -which was 
formed on this fide; the other fide a n of this mouth, 
being border’d by part of the old arms ad, ad. Next 
day the lips of the new mouth was difpofed in form of 
a conical nipple, and the new arms fmaller than the old 
ones. The fame day the returned portion a c, fig. 408. 
which the day before made the right angle c a b, with 
the other part a b, not returned, was drawn nearer to 
this laft part, and made an acute angle therewith, as at 
fig. 409. where a c reprefents the returned portion, and 
a b that portion not returned. The doubtful part e, re¬ 
main’d as before; a worm being given to it, fell upon 
the old arms, was feizcd, conveyed to the new mouth, 
and fwalloweu in an hour’s time, and the portions a c, 
a b, and a e, fig. 409. were fwejled with the contents 
of the worm. 
Four days after, its form was much different, as ap¬ 
pears by a companion of the figures 410, and 411, whereof 
a c, reprefents the returned part, and a b, the part not 
returned. Having now but one common month a, fig. 
410. the new arms are feen between a and t, the equi¬ 
vocal part e as in the figures. 
This form was changed but little in fifteen days, as is 
feen on comparing the two foregoing figures ; the old 
m pus Yv'liich were before between a and t being vaniflied, 
and a head at u, fig. 411. which was at firft taken for
