each cell. 
I muft further add, that I believe, if the curious, 
with good microfcopes, at the fea-fide, and at dif- 
ferent feafons of the year, would flridtly examine 
many of thefe beautiful fea-produdtions, hitherto 
claim’d by the botanifts, they would find, that feve- 
ral of the teftaceous tribe proceed from fome kinds 
of the larger corals, as well as, I am perfuaded, they 
will find, that many owe their original to the fmaller 
corallines : and we are the more encouraged to try, 
fince we obferve, that various fhapes and Rages of the 
fame animal are no new tiling in the laws of nature.
