Duhamel showed that when plants growing on the sea shore, the ash of which is mainly soda, are grown inland, the soda is gradually replaced by potash, and this was confirmed by Louis Claude Cadet, who analysed the ashes of kali plants on Duhamel s estate at Denainvilliers. John Mitchell had completely confused the two kinds of alkali. Guyton de Morveau said that Marggraf and Duhamel had in a way exhausted the resources of chemistry without reaching success in attempts to find an economical process for making soda from common salt, which is much to be desired. Success was first achieved by Leblanc (see p. 563).
