Ellis’s Corallines, pi. 38. fig. 4. 
The genus Sertularia affords a moft curious proof 
of an animal body under the appearance of a vegetable. 
So very great is the fimilarity which moft of the fpe- 
cies bear to plants, that they have almoft univerfally 
been regarded as a fort of fea-moffes, and as fuch have 
been defcribed by moft naturalifts; but the late inge¬ 
nious Mr. Ellis feems to have clearly proved that 
thefe apparent vegetables are no other than real marine 
polypes or hydras ; which differ from the frefh-water 
polypes in being provided by Nature with a horny 
cafe
