Pincussbattery is a combination of zinc and silver with chlorideof silver; it is more constant than those previously de-scribed, and is very portable, but is easily put out oforder. Constant batteries usually comprise a porous vessel of 28 ELECTRO-THERAPEUTICS. earthenware, containing one metal, bathed in one fluid ;this vessel is set into a larger jar, containing the othermetal and fluid. The standard element of this class isthat of Daniell, composed of zinc (in a weak dilution ofsulphuric acid) and copper (in a strong solution of sul-phate of copper). This excellent battery requires fre-quent cl
