 pearance of a Net. The Spaces between the Holes, on the 

 Iniide of this Coral, are full of the fmall Entrances into the 

 Infeds Cells, which are prefented magnified at Fig. 2). 



The Back or under Part of the Coral is magnified at jp, 

 to iliew that there is no Opening to the Cells on that Side.

The common Sea-infecls Cell, with which mofl: marine 

 Bodies are over-run, is now-and-then found raifing itfelf into 

 a leafy Figure, like the preceding Corallines ; but the fame 

 great Regularity and Order is not fo flrictly obferved in the 

 Difpofition of the Cells. 



Fig. a, N°. 4. gives us the natural Appearance of this irre- 

 gular fpongy Coralline, Part of which is magnified at Fi-

This has given many ingenious Perfons an Opinion, that 

 the Keratophyta are of the fame Nature ; that is, that they 

 are no more than Sea-plants, on which different Species of 

 Sea-Infeds build their calcarious Nefts ; but this, we hope, has 

 been already explained fufficiently ; and fome of the miftaken 

 Notions, concerning their Formation, removed.
