In the fusion curves D and E the different temperatures 

 below 20°C. were maintained by dropping ice-cold water into 

 the bath at different rates of rapidity. 



These five curves reproduced on the left side of Plate I 

 coincide almost exactly. But at lower temperatures the deviation 

 between the curves D and E exceeds the limits of experimental 

 error. The curves are nearly straight lines being only very 

 slightly convex towards the axis of temperature. Of some of 

 these curves only short sections have been observed owing to the
