Criticizing F. Zambonini's Natrod:tvyne (1910 ; 6th List), it is pointed out that in all analyses of davyne there is an excess of sodium over potassium- if, therefore, ' natrodavyne ' is to imply the absence of potassium, then A]calida~yne would be a more suitable name. Further, as carbon dioxide may be present or absent in davyne, it is necessary to distinguish between earb~Maeyne and acctrbodavyne. Akrochordite. G. Flink, 1922. Geol. F6r. FSrh.
