| Description | His paper on 'The conductivity of salt vapours' has been carefully considered and the Chairman of the Sectional Committee and a Secretary of the Royal Society are prepared to recommend it for publication in the 'Proceedings [of the Royal Society]'. Some criticism has been made on a remark on the bottom of page 13 of the paper to the effect that 'Garrett observed that the current varied with the temperature according to Richardson's law, and it therefore appears probably that in these conditions the thermionic effect of the salt plays the chief role'.
This appears to imply that the law of temperature variation for conductivity in vapours given later by hum, which is slightly different to the on referred to, can be used to distinguish between conduction in vapours and emission from surfaces. As a matter of fact it is suggested that the two formulae are identical within the limits of experimental error.
The paper should also be improved by some verbal revision, and if he desires to have the manuscript returned Harrison can send it. |
