Marine Infefts are frequent among the fea-rocks, and on the 

 fhores, after high fpring-tides, and florms. 



51. "ThefmallSea-Sfar, with thirteen obtufe rays, of a reddifh 

 brown colour (a), has been found among the rocks at Neivbiggen. 

 I have one with fourteen rays, or arms, of the fame colour, from 

 the more of the bifhopric of Durham* 



52. The Sea-Star \vith five rays (b) is common among the fea- 

 rocks at Hartley, and among many other rocks on the coaft. 



The Sea-Stars move in all directions. They have the power of ; 

 fixing themfelves to any thing, at pleafur-e with their clafpers or 

 tentacula, which ferve alfo for inftruments to get their living. 

 When they have found their prey, they inclofe it in their arms, 

 as in a net, and convey it with great dexterity to the mouth, 

 which is in the center. 



53. Th'e large loco-motive Sea-Nettle, or Medufa (cj, which floats 

 on the waves, is often call on more by the tides. I have feen it 

 in great abundance on the fands between Crefswell and Drurldge. 

 It looks like a mafs of jelly, orbiculated and convex, whitifh and 

 femipellucid, plain underneath, with an eehinated circle, adorned 

 with whitim-brown radii. There are feveral varieties of it f .
