About This Book

An encyclopedic survey that first catalogs marine animals, algae, and shellfish, describing habitats, curious behaviors, reported antipathies, and numerous folk remedies and practical uses attributed to specific species, organized by ailments and applications. The later portion treats metals and their ores—including gold, silver, mercury, copper, and brass—describing modes of occurrence, extraction, alloying, testing, gilding, and decorative and monetary uses, alongside technical observations and medicinal remedies derived from metallic substances, with systematic lists and practical instructions interwoven throughout.

CHAP. 56.—CHIAN EARTH; THREE REMEDIES. SELINUSIAN EARTH; THREE REMEDIES. PNIGITIS; NINE REMEDIES. AMPELITIS; FOUR REMEDIES.

Among the medicinal substances, there is the white earth of Chios also, the properties of which are the same as those of Samian earth. It is used more particularly as a cosmetic for the skin of females; the Selinusian2284 earth being also employed for a similar purpose. This last is of a milk-white colour, and melts very rapidly in water: dissolved in milk, it is employed for whitening the plaster coats on walls. Pnigitis2285 is very similar to Eretrian earth, only that it is found in larger masses, and is of a glutinous consistency. Its effects are similar to those produced by Cimolian2286 earth, but are not so energetic.

Ampelitis2287 is an earth which bears a strong resemblance to bitumen. The test of its goodness is its dissolving in oil, like wax, and preserving its black colour when submitted to the action of fire. Its properties are emollient and repercussive; for which reason, it is used in medicinal compositions, those known as “calliblephara,”2288 more particularly, and in preparations for dyeing the hair.
