others, because the extrapolation from the triple point is a very short 

 one and does not admit of much question, and the transitions above 

 the triple point, on which the extrapolation is based, do not show the 

 lag effects so prominently as at atmospheric pressure. There seem 

 to be no values of AV at atmospheric pressure for comparison. Bellati 

 and Romanese ^° give for the latent heat of the transition 11.89 cal. 

 against 11.6 cal. found above. The agreement is closer than usual. 

 There seem to be no previous measurements of the effect of pressure 

 on the transition.
