brane. We obfcrved only in thefe dwarf coriaceous fpccinicns the 

 true frucftification, wliich is tubercles immerfcd in the frond, and 

 projeding from it, and opening at the point. In one of our 

 fmalleft fpecimcns, a largilh tubercle appears ftanding on the fur- 

 face of the difk, and not immerfcd : but thefe tubercles are rarely to 

 be obfcrved. In general the plant Ihoots out to fome length; in 

 this ftate it has only fmall feeds like granules (ihe chara6i:er of an 

 Ulva) difperfed over the whole frond, fo that one would conclude 

 it to be an Ulva. 



May it not happen, that having fulfilled the purpofe of its pro- 

 duclion, viz. the fruilification, the growth of the plant accommo- 

 dates itfelf to its juft limits ; but, failing in that, it runs out wild 

 and iffegular, fportive and impatient of all controul ?
