Atthis time of the year the ice splits up into spars or prisms, bounded byangles proper to substances crystallising in the hexagonal system. The temperatures at which water passes from one state to anotherare taken as fixed points on the thermometer scale ; namely, the zerocorresponds with the temperature of melting ice, and the temperatureof the steam disengaged from water boiling at the normal barometricpressure (that is 760 millimetres mea
