The liquid was distilled several times, then shai<en with mercury and 

 again subjected to fractional distillation in an atmosphere of nitrogen after 

 being completely dried. It boils at 46 .8 C. constantly; it solidifies (Timmer- 

 mans) at — 111°. 6 C. At the boiling-point y. has the value: 27 3 Erg. The 

 specific gravity at C. was: 1.2921 ; at 20 ' C. : 1.261; at 46^ C. : 1226. In 

 general at f C. : d4o = 1.2921 -0.00147/. 



The temperature-coefficient of y is constant; its value is 1.75 Erg per degree.
