by rising with rising pressure, exactly as do some of the curves for 

 water. The abnormality is doubtless due to an entirely different 

 cause, however. In this case the effect is to be explained by the 

 delayed freezing of the kerosene. Kerosene is not a simple pure 

 substance, but is a mixture of several components with different 

 melting points. Freezing under these conditions is not .sharp, but is 

 spread out over a considerable interval of temperature or pressure as 

 the case may be. Neither is there any necessity that the freezing
