Left any doubt fhould (till arife in this abftrufc 
part of the operations of nature, it may be proper 
that I lhould explain myfelf further, by fhewing 
that there are a great many zoophytes, which were 
formerly called Corallines, now Sertularias and Cellu- 
larias, that from a creeping adhering tube fend up 
feveral tingle animals, others fend up feveral branched 
animals. To give an inftance or two of each, I 
fhall mention the Sertularia uniflora, or Single bell- 
Ihaped Coralline (fee the Eflay on Corallines, PI. XIV. 
fig. A and B) and the Cellularia anguina, or Snake’s 
head coralline (fee the fame Eflay, PI. XXII. fig. C) 
both which, like our A&inia fociata, fend up diftindt 
animals with one mouth each. 
Whereas the Sertularia pumila, or Sea oak coral- 
line (fee Eflay on Coralline, PI. V. fig. A) and 
the Cellularia burfaria, or Shepherd purle coralline 
(fee the fame Eflay, PI. XX. fig. A) fend out ani- 
mals, in the form of fpikes or branches, that have 
many mouths from their own creeping and adhering 
tubes j and yet both thofe with one mouth to each, 
and thefe with many, I efteem as fo many diftindt 
animals, notwithftanding their being connected by 
an adhering tube, as I have faid in the inftance of 
the tree and its fuckers. 
To conclude, my Lord, the importance of the 
difcovery of this new animal to natural hiftory is 
this, that it clears up that much-difputed point, 
which is, that the extenlion or increafe of the 
fubftance of thefe zoophytes is of an animal, and 
not of a vegetable growth (as fome late authors would 
have us think) by thus making the fadt more clear 
and evident to our fenfes.
