He begins with obferving, that they don’t come 
near to any one genus of Zoophytes, neither in their 
ftru&ure nor chemical principles ; that fome fpecies 
have a peculiar appearance, fome approach to Fu- 
cus’s, many are like Confervas ; but that all of them 
are very diftinCt from them, and from all vegetables, 
on account of their lapidefeent fubftance. 
That they differ in their chemical principles 
from Zoophytes ; for when they are burnt, they 
fmell like vegetables : and that, according to Count 
Marfigli’s Experiments (Hift. Mar. p. 73.) they 
neither contain a volatile fait, or animal oil. 
That the pores, in their calcareous fubftance, are 
too fmall for polypes to inhabit them j and that the 
pores of Fucus’s prove them to be as much animals 
as the Corallines, even when their pores are rendered 
more vilible, by having the calcareous fubftance, 
that furrounds them, difl'olved by an acid. 
That the great Jufiieu, in his diligent refearches 
after marine productions could fee no vilible token 
of life in them. 
That Mr. Meefe, who has lately wrote a Flora 
Frifica, has found a Coralline growing upon a heath 
in Fried and ; which, Dr. Pallas fays, is a ftrong 
proof of their vegetable origin. 
Laftly, that their fructification is fo nearly ana- 
lagous to thofe of Fucufes and Confervas, that he 
likewife takes that to be a proof of their belonging 
to the vegetable kingdom. 
To proceed then. — Dr. Pallas, after telling us 
that Corallines are vegetables, fays, that fome of 
them are like Fucufes.
