In this case, as well as in that of nitric peroxide, it is inadmissible to use the expression “ tempera¬ 
ture of volatilization,” which by definition applies only to solids. (Phil. Trans., 1884, I.) Nor is 
“ boiling-point” a correct term, for ebullition does not take place. With liquids which are known not 
to dissociate, the expression “ vapour-pressure ” may of course be used.
