Supergene (geology) and something called gossan cap
In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation (i.e. water derived from precipitation) with concomitant oxidation and chemical weathering. The descending meteoric waters oxidize the primary (hypogene) sulfide ore minerals and redistribute the metallic ore elements. Supergene enrichment occurs at the base of the oxidized portion of an ore deposit. Metals…

Arsenic and Old Leeches
In 1816 Dr. James Rawlins Johnson published his Treatise on the Medicinal Leech. Besides the aforementioned methods of leech use, he studied the leech itself with exacting care.
