Physiological Potency of Dilute Traces


THE attention of readers must have been arrested by the brief reports contributed to NATURE1 at various times by Mr. Hugh Ramage, an eminent spectroscopic chemist, on the concentration of certain metals in special tissues of plants and animals, up to amounts spectroscopically measurable. The explanation would be that the ultra-infinitesimal amounts of these metallic substances that are present in the food that passes through the organism must be arrested in the organs concerned until the accumulation becomes sensible. An opening seems here to arise into the chemistry of minute traces, which is the aspect of that science that promises most for mathematical development.
