TitleLetter from J [John] Brown, Helen's Bay, to [Joseph] Larmor
CreatorBrown; John (1850-1911); British manufacturer
Date29 September 1886
Description'The drop of water connection does not exactly neutralize the potentials of Cu & Zn'. Its extent depends upon the state of their surfaces. He describes the experiment, with a small diagram. He notes that if the metals of the quadrants were iron and copper, then joining them by a drop of potassium sulphide solution would increase the difference of potential near them. He thought of including an experiment of this kind in the paper, but afterwards thought it too simple and therre was something similar in his paper in the Philosophical Magazine. It might give interesting results to try long damp thread connections - but how long and how damp? Can Larmor's mathematics help? He did not place much value in Everett's opinions.
