Adiantum, _Maiden-hair_, is desiccative, attenuant, and moderately discutient; and with regard to heat and cold, it holds an intermediate place. It, therefore, cures alopecia, discusses swellings, proves lithontriptic when taken in a draught, dries up expectorations from the lungs, and stops defluxions of the belly. * * * * * COMMENTARY. Theophrastus says that it derives its name from its property of not being wet in rain. He adds, that it promotes the growth of the hair. (H. P. vii, 13.) Nicander says the same of it. (Ther. 846.) According to Apuleius, it is the same as the callitrichon, polytrichon, and asplenon. There can be no doubt that it is the _A. Capillus Veneris L._ Dioscorides describes another species by the name of τριχόμανες, which Sprengel and Schneider agree in referring it to the _Asplenium Trichomanes L._ Stackhouse agrees with them respecting both these species. The syrup of capillaire, which still holds its place in the shops as a favorite domestic medicine, is prepared from the _Adiantum_. Αΐζωον, Sempervivum, _Wall-pepper_ (or _House-leek_?), of which there are two varieties. It cools in the third degree, is moderately desiccative and astringent, and is applicable for erysipelas, herpes, and inflammations from a defluxion. * * * * * COMMENTARY. Our author, copying from Galen and Aëtius, describes two species which seem to be the _Sempervivum arboreum_ and _Sedum rupestre_. Dr. Lindley, however, refers the latter to _S. ochroleucum_. Dioscorides has a third species, which may be referred to the _Sedum stellatum_. The greater house-leek is praised by Dioscorides as an application for headache, for the bites of venomous spiders, diarrhœa, and dysentery; as an anthelminthic when drunk with wine; for stopping the fluor of women in a pessary, and as an application to the eyes in ophthalmy (iv, 88, 89.) Macer Floridus commends it in menorrhagia. He calls it _acidula_. Serapion, Avicenna, Rhases, and Haly Abbas merely copy from the Greeks. Even Ebn Baithar has nothing original under this head. These plants, although not retained in our Dispensatory, are still allowed to possess medicinal properties. See Lindley (Veg. Kingd. 345.) It is still retained in some of the foreign Dispensatories, and is held to be refrigerant and astringent. Ἀετώνυχον, Ætonychon will be treated of under the head of _Stones_. Ἀθηρά, Pulticula, _Pap_, is a kind of puls fit for being supped, which is prepared from ground spelt or from any corn, and agrees with children. It answers also for cataplasms. * * * * * COMMENTARY. Dioscorides gives the same account of it. It is the _Puls fritilla_ of Pliny. Matthiolus says it is called _bouillie_ in French, i. e. _pap_. Hesychius speaks of its being prepared from wheat, and Pliny from rice. Ἀιγίλωψ,
