Abstract

Description is made of a capillary electrometer designed for physiological studies. The use of this instrument with a thermionic amplifier makes possible the recording of small changes in potential without requiring the construction of an extremely sensitive capillary.

The advantages of the instrument described are the use of a closed acid chamber, an upright position of the capillary, and of even greater importance, the relatively vibration-free meniscus which is obtained by placing the capillary midway between two balancing columns of mercury.
