Page 505 - When a double salt is formed by the union of two neutral salts, no disengagement of heat occurs. 5. When a neutral salt is converted into a basic salt, the combination is accompanied by the disengagement of heat. 6. When one and the same base displaces another from any of its neutral combinations, the heat evolved or absorbed is always the same whatever the acid element may be.
Page 480 - Some of the largest deviations from the general mean occurred when this movement was very slight. As to the direction of the elliptic revolution, it was, in the majority of instances, indirect, or contrary to that of the motion of the hands of a watch. In only four instances out of twenty-three, was a motion in the contrary direction observed. 28. ON THE PENDULUM EXPERIMENT. By Prof. JD DANA. [ Not received.] 29.

Page 117 - ... the same relation to each other as the potash salts. The relation of the salts of potash to those of soda, in times of equal diffusibility, appeared to be as the square root of 2 to the square root of'S; which gives the relation in density of their diffusion molecules, as 2 to 3.
