HISTORY OF ZOOPHYTOLOGY. 
another, that they cannot separately exist, and therefore have 
not hesitated to call them constituent parts of the same body, 
and that the polype-like suckers are so many mouths belonging 
thereto. 
44 Now, for the smallness of the pores, which the Doctor has men- 
tioned here (among the Corallines) to be a contradiction to ani- 
mal life ; he certainly has forgot one circumstance, when he in- 
troduces the Coralliurn purnilum album, (Essay Cor. t. 27. f. c.) 
or his Millepora calcarea (Pall. Elench. p. 265,) as an animal, 
which is, that he there says, it has absolutely no pores at all. 
64 As there can be no doubt, but every part of what is called 
Coralline is necessary to make out such an animal, or being, it 
will be very difficult, if not almost impossible, to determine the 
proportion there ought to be between softer and harder parts ; 
and therefore it cannot be thought unreasonable to say, that in 
some of this tribe the stony parts are by much the greater part 
of the whole, especially as Doctor Pallas’s objection can be only 
against the crust, or lapidescent part, as the inside of many of 
them is far from being hard, being exactly like a Sertularia, so 
that I do not know if it would not be a good definition to one 
well acquainted with that tribe to say, a Coralline is a Sertula- 
ria, covered with a stony or calcareous crust ; if the mouths 
should happen to be very small, their number may make up that 
deficiency. We see in the greatest number of corallines their 
surface full of holes ; we saw the same in Escharas and Mille- 
poras thirty years ago ; since that time magnifying glasses have 
been improved, so as to shew us, that they are all orifices for 
polype-like suckers ; why should not we now admit that glasses 
may be still more improved, so as even to make us able to see 
what may be the intention and use of these minute orifices, which 
according to all rules of reasoning, we must suppose to approach 
in nature to them they are most alike. From this extreme mi- 
nuteness then of the pores of these Milleporse, confessed to be 
zoophytes, as well as those of Corallina officinalis as before men- 
tioned, it is no great matter of surprise, that Doctor Jussieu 
could not perceive any animal life in the corallines, nor Doctor 
Schlosser in the Millepora calcarea. As these experiments 
ought to be attended with many convenient coinciding circum- 
stances that do not often happen to persons who only go to the
