TitleLetter from [Horace Tabberer Brown], 52 Nevern Square, Kensington, to [Joseph] Larmor
CreatorBrown; Horace Tabberer (1848-1925); British chemist
Date27 September 1899
DescriptionLarmor's letter of that morning has allowed Brown to 'see the light' after 18 months. He has attempted to picture the form which three layers of equal density would take and has been unsuccessful. He now sees the all-important function of the wide flat rim and that the rate of diffusion depends upon its relation to the width of the rim, not the size of the opening. Very important results must follow, which may be tested by experiment. A small circular depression in a large plate of glass filled with alkaline solution ought to take up carbon dioxide faster than a thin cylinder filled to the top. He proposes to try this by putting a wide collar around such a cylinder. The phenomenon of gaseous effusion ought to follow the same law, he thinks. He notes the work of [Thomas] Graham and suggests further experiments.
