Apparatus for obtaining laugiiing-gas. which yield ammonia, which is a colourless gas of strongodour and taste now obtained from gas-works. To obtain AMMONIA heat equal parts of chloride ofammonia (sal ammoniac) and quick-lime powdered (seepage 87). The gas must be collected over mercury, be-cause it is very soluble in water. Ammonia is useful torestore tipsy people and fainting ladies. A solution ofammonia is used for cauteries. Ammoniacal gas is re-markable for its solubility in water. To prepare thesolution the gas is forced thmugh a series of flasks. Thetubes carrying the gas should be continued to the bottomsof the flasks, else Ae solution, being lighter than water LAUGHING GAS. 87 the upper portion alone would be saturated. The tubescarrying away the solution are raised a little, so that the
