The porous cup acts mechanically as a diaphragmto prevent the deposit of zinc on the platinum, which, inthis arrangement, is kept clean and bright, and thereforein the best condition to conduct the current (Fig. 22). Inthe combination known as the Bunsen, the arrangement ofthe elements is the same as in the Grove, except that thenegative plate is carbon instead of platinum. The price ofsuch a combination is much less than that of the Grove, butthe carbon does not long retain its properties, and must be FORMS OF GALVANIC COMBINATIONS. 51 frequently well washed and baked When the carbonsare fresh, the action of this battery is very powerful, some-what more powerful than the Grove, but it is not as con-stant as the latter. Owing to the fumes given off by them,and the expe
