 confequently include, if not ail the aquatic, in great probability all 

 the marine Tremellce, 



We mull again call upon the candour of the Society not to im- 

 pute thefe corrections of our great mailer Linnaeus to any finifter 

 views. — We fee errors, we (late them. 



It is with the utmoft diffidence, that, after having faid io much, 

 we prefume to fuggeit any other defcriptions in the room of thofe 

 which we have rejected ; but as it is ablolutcly neceffary that fomc 

 fhould be propofed, we would beg leave, from the very imperfect 

 'light by which we at preient walk, to define the characters as fol- 

 lows : 



Fucus — Sem/na, tuberculh cotifertis apice dehifcentibus, innata. 

 Conferva — Semina y tuberculh rotundis folitar'tis claufs fronde ex- 



tantibus y adntitis, inclufa. 

 Ulva «— Semina Jimpliciffimafrondi innata, undiquefparfa. 



In ftating thefe ideas of character we are thoroughly confeious of 

 our imbecility and ignorance. We profefs only to eftabliih certain 

 data from the appearance of what may be juftly deemed fructifica- 

 tion, and conltitute our differences accordingly. 



Before we difmifs this fubject it may be proper to obferve, that 

 in many Fuel two forts of fructification are to be feen — one warty 

 tubercles, and the other numerous fingle grains. The obfervation 

 of thefe has again led ftudents to imagine that they are the differ- 

 ences of lex. Undoubtedly both thefe appearances are of the 

 female flower, i. e. feminal — We have obferved them occafionally 

 in F. alatus t vermicu/aris, and hypoglojotj, fcattered along the rib or 

 nerve, or on the membrane on each fide of it. Some few of thefe
