e ordinary form of bridgethe interchange is more difficult, for the coils to be comparedhave generally to be kept in water, and the two pairs ofbinding-screws of the bridge are a considerable distance apart,and thus the shifting of the coils to change their connexionsis a somewhat inconvenient matter. At the meeting of the Physical Society on Feb. 2o, Prof.S. P. Thompson made some suggestions as to the manner inwhich the ordinary slide-wire bridge might be adapted sothat Carey Fosters method could be conveniently applied. We have, during the past three years, at the CavendishLaboratory frequently had occasion to make use of the ordi-nary bridge for comparing coils and determining temperature-coefficients ; and have accordingly found it necessary to devisecome simple arrangement by which the easy and rapid inter-change of the resistances under comparison could be providedfor. • Communicated bv the Physical Society.
