Arseniuretted Hydrogen.—This body, liquefied by Dumas and Soubeiran, did not solidify at the lowest temperature to which I could submit it, i. e. not at 166° below 0° Fahr. In the following Table of the elasticity of its vapour the marked results are experimental, and the others interpolated:—

The following bodies would not freeze at the very low temperature of the carbonic acid bath in vacuo (-166° Fahr.): —Chlorine, ether, alcohol, sulphuret of carbon, caoutchoucine, camphine or rectified oil of turpentine. The alcohol, caoutchoucine and camphine lost fluidity and thickened somewhat at -106°, and still more at the lower temperature of -166°. The alcohol then poured from side to side like an oil.

Dry yellow fluid nitrous acid when cooled below 0° loses the greater part of its colour, and then fuses into a white, crystalline, brittle and but slightly translucent substance, which fuses a little above 0° Fahr. The green and probably hydrated acid required a much lower temperature for its solidification, and then became a pale bluish solid. There were then
