Lapides, _Stones_; all kinds are desiccative like earth; but the Hæmatites, or _Blood-stone_, is astringent and desiccative in a considerable degree, so that it agrees with trachoma of the eyelids, and if they are free from inflammation it is to be used with water; but if inflamed, with an egg. It is drunk also with advantage for spitting of blood; and it restrains the fungous flesh of ulcers. The _Schistos_ or _Scissilis_ has similar properties, but is weaker: and after it the Galactites, or _Milk-stone_. The Melititis, or _Honey-stone_, has also a certain degree of heat. The Moroxus (called also Leucographis), being so much softer than the others, and possessing no active quality, is much more mild, and occasions less pain; it is, therefore, used as an application to the soft parts of the body with cerate for the cicatrization of ulcers. The greenish _Jasper_, being possessed of stronger powers, attenuates cicatrices and pterygia. The Green Jasper is useful in stomach complaints, when appended as an amulet, and when worn in a ring. That called the _Judaic-stone_ breaks renal calculi, and hence the moderns have called it Tecolithos. The _Pyrites_ acts as a powerful discutient of tumours and coagula; and when it is not at hand, the _Molaris_ may be used instead. The _Phrygian_, in addition to being powerfully desiccative, has also some astringency and pungency; hence it is repellent and discutient, and is therefore mixed up with ophthalmic remedies. The _Ageratus_, being possessed of astringent and discutient powers, is of use in inflammations of the uvula. The flower of the _Asian-stone_ is composed of so subtile parts that it corrodes flabby flesh without pungency. The _Gagate-stone_, being considerably desiccative, agrees principally with chronic cases of emphysema. The _Magnet_ (called also the Heraclean-stone) has similar powers to the Hæmatites. The _Arabian-stone_ is like ivory, desiccative and detergent. Some give those affected with stomach complaints a draught composed of burnt _Alabaster_. The Smeris, _Emery_, having detergent powers, cleanses the teeth. The stones found in _Sponges_ break down renal calculi; and those formed on the Argæan mountain of Cappadocia are possessed of similar powers, and in like manner the stone called _Ophites_, which is appended as an amulet with advantage to those bitten by the viper. The _Ostracites_ and _Geodes_ are said to be considerably desiccative so as to cure inflammatory swellings. The Retrimentum Naxiæ cotis, _filings of the Naxian Whetstone_, is said to be refrigerant, so as to repress the breasts of virgins, and the testicles of children. The filings of the _Cos oleraria_, being detergent, suit with alopecia. It is said that the _Hieracites_ and _Indian-stone_, when appended as amulets, stop the discharge of blood from hemorrhoids, and that the _Sapphire_, when drunk, relieves persons bitten by the scorpion, and the _Aphroselinum_, epileptics.
