COMMENTARY. The account given by our author of the medicinal properties of _Urine_ is abridged from Dioscorides and Galen. Galen rejects, with disgust, the internal use of it. Some, he says, have given the urine of a boy for the cure of orthopnœa; but he justly remarks that there is no want of other remedies for this affection, and that in fact the article in question has no peculiar virtue in the complaint. Most of the other authorities, however, sanction the use of it in this case, as for example, Dioscorides, Avicenna, and Rhases. They also recommend urine to be drunk for the cure of the bite of the viper, for deadly poisons, and incipient dropsies. Dioscorides recommends the sediment of urine as an application to erysipelas; upon which practice Galen remarks that when the affection is still hot such an application must be quite unsuitable; but that when cooled, it or any other discutient is indicated. Those who desire to know more fully the views of the ancients on this subject, are referred to Dioscorides (ii, 99); Galen (De Simpl. 10); Serapion (c. 448); Avicenna (ii, 2, 716); Rhases (Cont. l. ult. i, 749); Haly Abbas (Pract. ii, 517); Ebn Baithar (i, 191.) The last of these is particularly full under this head. Πανγράτιον, Pancratium, _Sea-daffodil_, in appearance and powers is like the squill, but is weaker. * * * * * COMMENTARY. There are two varieties of the _Scilla maritima_, or Squill, namely, the white and the red. The _pancration_ would appear to be the red variety. See Alston (Mat. Med.); Pereira (Mat. Med. 651); and Lindley (Veg. King. 203.) Dioscorides, like our author, states of it, that it has the same powers as the squill, but in a weaker degree; and that it is prepared in the same manner, and used in the same affections; for example, in diseases of the spleen and dropsies. (ii, 203.) Galen and Aëtius treat of it in nearly the same words as our author. We are in doubt whether the pancration be treated of by the Arabian authorities, with the exception of Ebn Baithar, who, it would appear, describes it under the name of _Kebal_. He, however, merely gives extracts from Dioscorides and Galen. (ii, 309.) Παλίουρος, Paliurus, _Christ’s-thorn_; the leaves and root of it are astringent, and hence they stop fluxes of the belly, and discuss phymata when they are not of a very hot nature. The fruit is of so incisive a nature as to break down stones, and relieve expectorations. * * * * *
