Abstract
Dr. HEDGES is to be congratulated on his book on “Liesegang Rings”, which gives for the first time a comprehensive survey of the subject together with a most extensive bibliography. It will be a valuable work. His description of my theory is adequate, except that he is incorrect in stating that it does not account completely for all the facts. The example quoted against it is a beautiful confirmation. The formation of zones of precipitated sodium chloride is due to the oppositely diffusing solutions of hydrochloric acid and sodium chloride being constrained by the capillary tube to pass near the deposited salt. This demonstrates the essential part played by the precipitate in removing the solute from the solution in its neighbourhood.
