me rheumatic affections. It is also used largely
in the making of glass.

Likewise for scrofula, seawater, being rich in chlorides and iodides,
has proved both curative and preventive. Dr. Sena, of Valencia,
gave bread made with sea-water in the Misericordia Hospital for
cases of scrofulous disease, and other states of defective nutrition,
with singular success.

Another Laminaria (_Saccharina_), with a single olive yellow
semi-transparent frond, yields an abundance of sweet "mannit" when
boiled and evaporated.

The Bladderwrack (_Fucus vesiculosus_), Kelpware, or Our Lady's
Wrack, is found on most of our sea coasts in heavy brown masses of
coarse-looking Sea Weed, which cover, and shelter many small
algae. Kelp is an impure carbonate of soda containing sulphate, and
chloride of sodium, with a little charcoal.

By its characteristic bladders, or vesicles studded about the blades
of the branched narrowish fronds, this Sea Weed may be easily
known.

These bladders are full of a glutinous substance, which makes the
weed valuable both as a remedy for the glandular troubles of
scrofula, and, when bottled in rum, as an embrocation, such as is
specially useful for strengthening the limbs of rickety, or
bandy-legged children. Against glandular swellings also the weed is
[504] taken internally as a medicine, when burnt to a black powder.
An analysis of the Bladderwrack has shown it to contain an
empyreumatic oil, sulphur, earthy salts, some iron, and iodine
freely. Thus it is very rich in anti-scrofulous elements.

The fluid extract of this Sea Weed has the long standing reputation
of safely diminishing an excess of personal fat. It is given for such
a purpose three times a day, shortly after meals, in doses of
from one to four teaspoonfuls. The remedy should be continued
perseveringly, whilst cutting down the supplies of fat, starchy foods,
sugar, and malt liquors. When thus taken (as likewise in the
concentrated form of a pill, if preferred) the Bladderwrack will
especially relieve rheumatic pains; and the sea pod liniment
dispensed by many druggists at our chief marine health resorts,
proves signally efficacious towards the same end. Furthermore, they
prepare a sea-pod essence for applying on a wet compress beneath
waterproof tissue to strumous tumours, goitre, and bronchocele; also
for old strains and bruises.

This Sea Weed should not be obtained when too fully matured, as it
quickly undergoes decomposition.
