Discussion on group I papers (heating, heat measurements, rating by heat) New York, February 26, 1913. (see proceedings for February, 1913)

Comfort A. Adams: There is one question I would like to ask of Mr. Dushman, concerning Mr. Langmuir´s paper. When Mr. Langmuir first published his work on Convection, I happened to be interested in the subject, and put the material into such shape that I could use it easily, but as the theory was only checked by tests on very small wires, I am in doubt as to the validity of the method when applied to large wires or to plane surfaces. I should like to know how far it is safe to go in this direction.
