great holes or pores observable in these Sponges were made by the erii*
ption of the included Heterogeneous substance (whether air, or Ibme
other body, for many other ssuid bodies will do the same thing) which
breaking out of the letter, were collected into Very large bubbles, and
so might make their way out of the Sponge, arid in their passage might
leave a round cavity 5 and if it were large^night tarry up with it the ad-
jacent bubbles, which may be perceiv’d at the outside of the Sponge, if
it befirst throughly wetted, and susser’d to plump it self into its natural
form, or be then wrung dry, and susser’d to expand it self again, which it
will freely do whil st moist: for when it has thus plump’d it self into its
natural shape and dimensions, ’tis obvious enoughthat the mouths of the
larger holes have a kind of lip or rising round about them, but the other
smaller pores have little or none. It may further be found, that each of
these great pores has many other sinal 1 pores below, that are united unto
it, and help to constitute it, almost like so many rivulets or small streams
that contribute to the maintenance of a large River. Nor from this
Hj/pothejis would it have been difficult to explicate, how those little
branches os Coral, sinal Stones, shells, and the like, come to be included
by these frothy bodies: But this inded was but a conjedure 5 and upon
a more accurate enquiry into the form of it with the Microfoope, it seems
not to be the true origine of them 5 for whereas Sponges have onely
three arms which join together at each knot, if they had been generated
from bubbles they must have had four.
