✦ Synopsis

Versuche mit Margarinen zeiglen, dai3 die Kristallisation durch den hohen Salzgehalt nach etwa -5OO C verschoben wurde. Nur bei hohem Gehalt an Milch in der Wasserphase wurdenwahrscheinlich infolge der Anwesenheit von festen Milchbestandteilen in den Wassertropfen -Temperaturen in der Nahe von -20° C gefunden. Die beschriebene spontane Kristallisation von Wasser in fein verteilter Form wurde auch bei Nebeln festgestellt. C. Lafargue'O fand in diesem Fall eine spontane Kristallisation von Wassertropfen (1 bis 20 p) in Luft bei -41OC. Er erklart diese Erscheinung mit der Annahme, dai3 die kleinsten Kristallisationskeime im Wasser einen Radius von 4.53 A aufweisen miissen, und berechnet hiermit, dai3 der Kristallisationspunkt von Wasser bei -41O C liegen mu& Compt. Rend. 230, 2022 [1950].
