In the course of the investigation that has been conducted at Union College by Prof. Charles B. Hurd and his student assistants, it was soon found that something more accurate than the Wheatstone bridge would have to be used in measuring the electrical conductivity of gels. This becomes evident if we consider that in such studies we encounter the measurement of very small changes in the total resistance, changes of the order of one or two parts in twenty thousand. Accordingly, a modification of the Carey Foster bridge was developed for this work.
