ni. b c are an enlarged view and a section of the elements. At the Exposition of 1867 were exhibited three batteries of this class: those of Farmer, American; Marcus, Austrain; and Ruhmkorff, French. The former consists of strips of copper and wedge-shaped blocks of an alloy arranged alternately in the form of a ring. The gas-burner. It was stated that thirty-six elements of this battery were equal to one of Grove's. Melloni's thermo-electric battery. In the battery of Professor Marcus, the positive and negative elements are both alloys: the former consisting of 10 copper, 6 zinc, and 6 nickel; and the latter of 12 antimony, 5 zinc, and 1 bsed for the negative element is not pure copper, but an alloy of 90 copper and 10 nickel (German silver). The elements are arranged in a manner resembling that of Marcus, their ends being immersed in water heated by means of a gas-burner. Eight or nine of these elements are considered by M. Becquerel to be equal to one of Daniell
