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. 63.—GRÆCANIC PAVEMENTS.

We must not omit here one other kind of pavement, that known as the “Græcanic.” The ground is well rammed down, and a bed of rough work, or else broken pottery, is then laid upon it. Upon the top of this, a layer of charcoal is placed, well trodden down with a mixture of sand, lime, and ashes; care being taken, by line and rule, to give it a uniform thickness of half a foot. The surface then presents the ordinary appearance of the ground; but if it is well rubbed with the polishing-stone, it will have all the appearance of a black pavement.
