The molecular latent heat at the boiling-point has been 

 measured directly by Kurbatoif (Zeit. Physik. Chem. xliii. 

 n. 104, 1903), who found the value 13600 cals. This value 

 is no doubt less accurate than that obtained as above. 

 Konowaloff {Zeit. Phys. Chem. xxxix. 1887) also quotes 

 Regnault, who obtained the value 15500 ; Traube {Zeit. 

 Chem. xxxiv. p. 423, 1903) assumes the mean value 

 14540 cals. at 360° G.
