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. 27.—AHTHRACITIS.3093

There is also a fossil stone found in Thesprotia, known as “anthracitis,”3094 and resembling a burning coal 3095 in appearance. Those who have stated that it is a native also of Liguria, are mistaken, in my opinion, unless perhaps it was to be found there in their time. Some of these stones, they say, are surrounded with a vein of white. Like those which we have mentioned above, they have a fiery colour, but there is this peculiarity in them, that when thrown into the fire they have all the appearance of becoming quenched and deadened; while, on the other hand, if they are drenched with water, they become doubly glowing.3096
