shaped, serrated, and about six inches long. These be- 
ing first washed clean, and sufficiently ed to resist 
putrefaction, are steeped in fresh water for about a 
week, changing it every day. After this, being boiled 
for a few hours in a little water, they form a clear trans- 
parent jelly ; which being mixed with sugar, and the 
Juice of a lemon or orange, affords a pleasant and refresh- 
ing dish. 
“Aneuadiuncte Dr Olaus Swartz, F. spinosus, (muri- 
catus of Gmelin) is eaten by the inhabitants of Suma- 
tra. This species occurs at the Cape, but is there 
lected. 
‘eons of the gigantic species, particularly F. potato. 
rum of Labillardiere, furnish various instruments ‘and 
household vessels, as well as food, to the native inhabi- 
tants of New Holland. 
A few of the smaller and more delicate kinds: seem 
capable of affording colouring matter or paint. Ginan- 
ni describes one under the name of Fucotintorio. This 
Mr Turner considers.as probably F, purpureus, which 
is very common in the Mediterranean, and gives outa 
beautiful chocolate dye in fresh water. 
It may be mentioned, that inthe North of Scotland, 
a kind of sauce for fish or fowl, somewhat resembling 
ketchup, is made from sea-weeds ; frequently from the 
eup-like frond or base of F. loreus. 
he mucus from the vesicles of F. vesiculosus and 
similar. ies, has been recommended in diseases of 
the glands, by Dr Russell; and F. helminthocortos, (Turn. 
t.. 233.) a small Mediterranean species, : ‘little 
known in Britain, has long been employed by medical 
menon the continent as a vermifuge, under the name 
of Moss or Coralline of Corsica. 
‘Some of the small red species are very ornamental 
when displayed in pictures ; and are used not only to 
embellish the eabinet of the naturalist, but apartments 
in . The foreign species chiefly employed for 
. this purpose, is F. cartzlagineus, which abounds at the 
, and is remarkable for the regularity andelegance 
of its form, and the richness of ‘its tints. 
The native species most generally used for formin: 
mimic’ trees or! landscapes, is F. coccineus. ‘The frond 
is con in carota ‘between ee 
and cartilaginous, much and irregularly branched; the 
ramuli subulate, disposed in alternate Semele three or 
four each. As formerly observed, two kinds of fructi- 
fication.are to be found on different ‘individuals of this 
cies ; both spherical sessile: capsules, and lanceolate 
silique. It is beautifully figured by Turner (THist. 
Fuc. t. 59.) and. also khouse, in a frontis< 
iece to one of the fasciculi of his Nereis Britannica, (p. 
106.) It is singular that this species, though very 
common, escaped the notice of Linnaus. When it is 
dexterously ded on very smooth white paper, or 
on the g interior of flat shells, the effect is 
very beautiful. It is generally of a bright red colour, 
but sometimes tinged white or yellow. It grows about 
three or four inches long. 
tion, it-is excelled only by F. asparagoides, (Turn. t. 
101.) a-species of much less frequent oceurrence. 
F. plumosus is likewise very ornamental... The frond 
is compressed, cartilaginous, much and i ly 
branched ; the branches are repeatedly pinnated, pro- 
ducing the feather-like from which the 
name has been —. It is of a purple colour, often 
inclining to: y ish brown. It is generally from 
three to five inches long; but-in the north of Scotland 
it reaches six-or seven inches, ~Still farther to the north

stems of fucus digitatus. 
F. alatus is the most abundant of all the small orna- F, alatus. 
mental sea-weeds, being very common on stalks of F. 
digitatus. The frond is. membranaceous, very tender, 
mid-ribbed, linear, subdichotomous ; the segments al-

of a fine purplish red colour.

uire to be soaked for some time in fresh water, and 
are the better for being repeatedly rinsed in re- 
newed basons of water, to cleanse away and extract as 
much as possible the sea-salt which adheres to them, or 
with which they are impregnated. The larger sort need 
no otherpreparation ;. but are to be dried between folds 
of bloating paper, and pressed in the manner of herba- 
ceous plants. The finer leaved fuci must be treated 
ina different way. After being washed, as above di- 
rected, in repeated waters, till no impurities of any 
kind. remain, they are to be separately floated out in 
a large shallow dish containing water, so that their 
most minute and delicate branches may be fully ex- 
panded. For disentangling the nice ramifications, a 
common pin, or a sharp-pointed peu, may be employed. 
A piece of stiff, but fine and smooth writing paper, is 
then to be gently introduced under the specimen, and 
the minute branchlets being again spread out where 
they may have been disordered, the paper is to be cau< 
tiously and slowly inclined, and at last drawn out, so as 
to contain on its surface the plant in its fully expanded 
state. After this, most of the delicate species, if care- 
fully dried and pressed, adhere to the paper by their 
own gluten, and require no farther care. Mr Turner 
mentions that he fixes the non-adhesive kinds by means 
of a cement made from F. ciliatus and crispus of our 
shores, These are boiled in water over a quick fire, 
and soon become melted : on: cooling, they form a glu- 
ten, not to be relied on as a'strong cement, but which 
is well adapted for a herbarium, as it neither imparts a 
stain like glue, nor a glare like gum. Ifthe paper be 
age, and a delicate 
membranaceous plant afterwards placed on it, it will 
become sufficiently fixed, merely by moderate pressure. 
Some collectors, finding that any kind of paper is apt 
to curl up, expand the delicate species over a -plate of 
ae and, after allowing the water to drip off, trans~ 
er the specimen carefully to the paper. 
To inland collectors, who occasionally make an excur- 
sion to the shore, it may be useful to know, that all the 
preparation that is necessary at the sea side is to dry 
the: specimens moderately in the free air, and tie them 
loosely up in strong brown paper. In this way they 
may beicarried to a great distance, and: kept for some 
days. -On being immersed in fresh water, they in gene-
