Pyramid Heat Measure. 

 While for heat, the Pyramid scale makes water freezing = 0, 



boiling =250; 

 The standard Pyramid temperature being = 50 of that scale, and the heat at 

 which iron begins to give out light = 1000 of the same, according to the Fahren- 

 heit statement of the Diffusion of Useful Knowledge Society's Natural Philosophy, 

 under head of Thermometer and Pyrometer.
