Laws of Fusion. We may thus sum up our results with the following laws of fusion. (1) A substance begins to melt at a temperature, which is constant for the same substance, if the pressure be constant, and is called the melting-point.

Page 117 - On partially liquefying carbonic acid by pressure alone, and gradually raising the temperature at the same time to 88° Fahr., the surface of demarcation between the liquid and gas becomes fainter, loses its curvature, and at last disappears. The space is then occupied by a homogeneous fluid, which exhibits when the pressure is suddenly diminished or the temperature slightly lowered, a peculiar appearance of moving or flickering striae throughout its entire mass.
