a small quan-tity of the anhydrous salt was firstadded and the cr^stals were almostentirely melted. Recrystallizationwas then started by running coldwater over the tube. In this way aperfectly definite temperature was se-cured within five minutes after start-ing the experiment. It was foundlater… … -6CM- Fig. 4. 7. THE EFFECT OF EXTERNAL CONDITIONS. In one experiment the external temperature was kept at 33° foran hour and the temperature of the salt was observed at intervals. 658 Bulletin of tJie Bureatt of Standards. [V0L3.N0.4.
