58 Q Natural Hiftol*y of 



Some of thefe little radical Tubes are difcovered by the Mi- 

 crofcope, to be full of Hooks, the better to fecure the Coral- 

 line, when it adheres to foft fpongy Subftances. The Hooks 

 on one of the Tubes are exprefled at Fig. F, in the Coral- 

 line, B. the natural Size of which is exhibited at Fig. 6, 

 N°. 3. 



When this Coralline is put into Vinegar, a ftrong Effer- 

 vefcence enfues, till the ftony or coral- like Coat is deftroyed; 

 and then the Cells, ft ill keeping their Shape, appear to be 

 made of a thin pliable Membrane, like thofe of the Hinges 

 and Roots : So that Roots, Hinges, and Cells appear now to 

 be one continued tubulous Membrane, only modified into 

 different Shapes.

 Creeping ftony Coralline. 



This Coralline differs from the former in having angular 

 Sides to its Cells, and in being of a more ftony brittle Tex- 

 ture. 



While I was at Ram/gate, in Auguft 1754, I obfer\^ed the 

 Polypes in the Cells, as defcribed at Fig. C; which is a mag- 

 • nified Branch of Fig. c, N°. 4. in the fame Plate.

This very fmall Coralline arifes from many 'Tubulin which
