Abstract
THE micro-electrode described by R. A. Weale1 necessitates the use of an electronic device, just for breaking the circuit, when the chain of silver crystals has reached the tip of the capillary tube. Furthermore, the micro-electrode proper has three disadvantages : (1) contact is easily disrupted in the capillary part; (2) resistance is comparatively high ; (3) the electrolyte remains between the crystals. These disadvantages are a consequence of the ‘feathery’ or ‘larchlike’ character of the chain of silver crystals, which do not adhere sufficiently to one another.
