Abstract
The method described depends on the fact that in adult leaves inspiration is stomatal rather than cuticular, so that, other things eing equal, the yield of watery vapour depends on the degree to Inch the stomata are open, and may be used as an index of their condition. In principle, it is the same as the methods of Merget and tahl. These observers used hygroscopic papers impregnated with eagents which change colour according as they are dry or damp, and tahl, who employed paper soaked in cobalt chloride, has obtained excellent results.
