There is a small Island in Lancashire called 
the Pile of Foulders, wherein are found 
broken pieces of old and bruised ships, some 
whereof have been cast thither by ship- 
wracke, and also the trunks and bodies 
with the branches of old and rotten trees, 
cast up there likewise ; where on is found 
a certain spume or froth that in time breed- 
eth unto certain shells,* in shape like those 
of the muskle, but sharper pointed, and 
of a whitish colour, wherein is contained 
a thing in form like a lace of silke finely 
* We have given with the portrait of the Bernacle 
a representation of this miraculous shell, it is the Le* 
pas Anatifera of Linnaeus and is thus described in 
Wood's" General Conchology." « A bluish white 
shell with five valves, four of which are faintly stria- 
ted ; the fifth, or dorsal valve, is smooth down the 
middle, and sulcated at the sides." 
" These shells are found in considerable clusters, from 
half an inch, to an inch and three quarters in length, 
and more than an inch in extreme breadth. They are 
seated on a flexible pedicle, which is sometimes a foot 
long." " This pedicle resemble asmall intestine : it is 
tendinous, cylindrical, and capable of great contrac- 
tion ; while the animal is alive it is filled with a glairy 
mucilage, which exudes after death, and leaves the foot 
stalk empty and withered."
