FUCUS VESICULOSUS, Linn.— BLADDER WRACK, SEA-OAK.

Synonimes :— Varec vesiculeux, Fr.; Mee-reiche, Germ. ; Strandklefver, Dan. ;Zee elk, Dut. ; Harter, Swed.

One of the Algse ( Quercns marina) abound-ing in the European seas. (Fig. Lynch.Hydroph. Dan. tab. 1.)

It is of a greenish-brown colour, abouttwo feet long, coriaceous, presenting vesi-cles disposed on the side of the median

nerve of its fronde, which is frequently di-chotomous and very entire at the borders.

Rüssel has recommended the mucuscontained in the vesicles as resolvent, ap-plied externally to goitre and scrofuloustumours.

If this plant really possesses any efficacy,it owes it without doubt to the small quan-tity of iodine which it contains.
