Of the former class are several very popular and use-ful batteries, of which the positive metal is usually zinc,while the negative may be of platinum (Smees battery),or lead or silver coated with finely divided platinum(Frommholds), or carbon (Stbhrers). The fluid is di-luted sulphuric acid. Zinc and carbon plates in a mix- / Fig.
