The unufual fight fo amaz’d our friend (who had his 
doubts), that he could fcarce believe his own eyes; 
for he had hitherto imagin’d, with many others, that 
thefe corallines were vegetables, and only the recep- 
tacles of animals, as many other plants are, and not 
the proper cafes, (kins, or coverings, of their bodies. 
The firfi: coralline that offer’d itfelf to our view, 
was n° i. ( Plate XXII.), where it is reprefented, in its 
natural appearance, climbing upon the podded fucus 
tf, with irregular threadlike ramifications, as at b ; 
one of which is exhibited magnified at A, in which 
we may obferve a broad dark line in the middle of 
the tranfparent flem and branches. This is part of 
the tender body of the animal, and feems as a fup- 
port for its feveral heads and flomachs, with the many 
hands or claws belonging to each : For at the top of 
each of the branches we may obferve a polype with 
twenty tentaculi, or claws, which do the office of 
hands, its mouth in the centre of them, and its fco- 
mach underneath, inclos’d in a fine tranfparent cup. 
The fine out-lines reprefent the horny fkin, or out- 
ward coat, that ferves this compound animal as a de- 
fence, in the fame manner as the fhells of teftaceous 
or cruftaceous lea-filh. 
The fkin or covering of the arms, that fupport the 
cups, is form’d in fmall rings, which gives the ani- 
mals the more freedom to move about dextroufly in 
feizing their prey. 
At letter B is the microfcopical reprefentation of a 
ftill fmaller coralline than the former ; the natural fize 
of it is exprefs’d at jig. 2. This creeps up, and 
twines round other corallines by fmall vermicular 
tubes, and fends out its curious (lender arms irregu-
