Natrod:tvyne (1910 ; 6th List) , it is pointed out that in all analyses of davyne there is an excess of sodium over po tass ium- if, therefore,

' na t rodavyne ' 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 dist inguish between

earb~Maeyne and acc trbodavyne.
