. The elements of physiological physics: an outline of the elementary facts, principles, and methods of physics; and their applications in physiology. Biophysics. PHYSIOLOGICA L PH\ [Chap. Fig. 78.—Stohrer's Battery. For the constant current, types of batteries may be taken in the STOHRER and the Stohrer's battery is figured in Fig. 78. It consists of a case containing twenty to thirty cells of vulcanite containing a plate of carbon and a plate of zinc, the cell being half full of dilute sul- phuric acid with a little bisul- phate of mercury for keeping the zincs amalga- mated. In one form a small quantity of strong solution of chromic acid is added, and gives the fluid a claret colour. The plates are fixed at the upper part of the box on a wooden support. The cells can be raised by a handle projecting at each end, so that they can be raised up to meet the plates, which are so caused to dip into the solution, and the cells can also be lowered so that the plates are out of the solution. When the cells are raised they can be fixed by a half turn of the handle. The plate carrier carries a sledge, which on its under surface makes contact by means of two metal rails with the plates. The plate carrier has numbers marked on it which indicate the number of cells in circuit when the sledge is over that place. The sledge should be so placed as to cover three wires of the cells, the central wire of which tells the number in circuit. The metal rails are long enough to make o O contact with the next cell before they break contact with the one before. So that if a current is being passed through a patient's body it is not necessary to break the circuit in order to throw in more cells, but.
