This fmall Coralline grows on Mufcle-fhells, and other 

 marine Bodies, like ft iff Briftles. When they are found dry 

 on the Shore, they all bend one way, like the fmall ones de-

Upon examining one of the Stems in the Microfcope, 

 it appeared jointed, like a Reed, as at A. From the upper 

 Part of each Joint arifes a fmall capillary Branch ; thefe 

 are difpofed, in refpedt to one another, in an alternate Or-

 thefe Joints are placed in Sockets, fmall cup-fhap'd Denticles, 

 in which I difcovered Polypes, like thofe defcribed in the 

 Lobfter's-horn Coralline ; and here reprefented at A^ Plate
