On a self-recovering coherer and the study of the cohering action of different metals

Abstract

In working with coherers, made of iron or steel, some special diffi­culties are encountered in the warm and damp climate of Bengal. The surface of the metals soon gets oxidised, and this is attended with variation of sensitiveness of coherer. The sensitiveness, it is true, does not altogether disappear, but it undergoes a considerable diminu­tion.
