Oss. Our knowledge of the fructification of the plants as- 
sembled under the genus Fucus, is not yet sufficient to enable us 
to improve the Essential Character, though confessedly imper- 
fect. The genus at present consists of a collection of marine 
plants, some of which approach in their habit and jointed struc- 
ture to the Confervas, still more of them resemble the membra- 
naceous or gelatinous Ulvas, whilst the strong and leather-like 
sorts are sufficiently distinct from either, From what I have 
seen myself, and from the discoveries of Major Velley and Mr. 
Stackhouse, I begin to believe that the leather-like Fuci will 
form two distinct Genera, and that the others must be divided

_™® There can be little doubt of the Fuci being the food of various 
kinds of fishes. They are indiscriminately used as manure by the farmers 
on the seacoast. The stalk of the F. escudentus may be eaten, as may 
also the F. saccharinus when boiled ; but the more crisp and tender leaves 
oie Fucus lanceclatus, holosetaceus, and pinnatifidus, are used as a sallad. — 
Fucus vesiculosus and serratus are collected on many of our northe 
shores, and burnt to make Kelp. : ae
