Lots to say: In due course I will add notes on the following subjects

• An improved description of the pressure dependence of the melting temperature of water substance.
• The possibility of an equivalent to the critical temperature/pressure for solid/liquid transitions. I don't think so, but I am not sure. It would definitedly be at extremely high pressure.
• A note on the importance of sublimation and the relative vapour pressures of water and ice in the growth of rain drops
• The metrological significance of the triple point temperature pressure and volume for water, and how to achieve a triple point cell
