Sea Girdles, or Sea Tangles. A species of Sea-weed. Hab. The coasts of Europe.

Med. Prop. and Action. From the property the stem possesses of becoming greatly reduced in bulk when dried, and again expanding when exposed to moisture, it has been used to form tents for dilating the os uteri. Professor Wilson, ¶ of Glasgow, recommends the use of tangle tents in preference to those of sponge, on the ground that they are much more easily introduced.
