Important: Safety Warning This page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes. This information has been left in for historical purposes but should not be acted upon. Compounds of great importance are formed by a combination of chlorine with metals and other substances. Most of the chlorides are soluble in water, and metals enter into as many combinations with chlorine as they do with oxygen. Chlorides melt at ordinary temperatures, and are more easily dissolved and fused than are their corresponding acids. Chlorides usually decompose when heated in a current of hydrogen, the result being hydrochloric acid and the pure metal. Simple ignition will decompose chlorides of noble metals, leaving the uncombined metal. If chlorides are heated with black oxide of manganese and sulphuric acid, the chlorine is eliminated. Chlorine abounds in the mineral world, chiefly in the metal sodium, in salt, etc., and is prepared by heating black oxide of manganese with hydrochloric acid--which forms a yellowish transparent gas 2 1/2 times heavier than air. Under a pressure of four atmospheres it is condensed into a liquid slightly heavier than water and which remains unfrozen at 220 deg. This gas unites with oxygen to form five compounds: with hydrogen it forms hydrochloric acid; with nitrogen, an explosive of great power, called per-chloride of nitrogen; and it forms several chlorides with carbon.

one of the most formidable diseases to which plants are liable, and often admitting of no remedy. It consists of a pallid condition of the plant, in which the tissues are weak and unable to contend against severe changes, and the cells are more or less destitute of chlorophyll. It is distinct from blanching, because it may exist in plants exposed to direct light on a south border, but is often produced or aggravated by cold, ungenial weather and bad drainage. The most promising remedy is watering them with a very weak solution of sulphate of iron. Many forms of the disease exist, of which those of clover, onions, cucumbers, and melons are best known. In medical practice, an affection in which the skin of the body, and especially that of the face, assumes a peculiar greenish cast, and hence is popularly known as green-sickness. The condition is closely allied to anæmia, and often associated with menstrual disturbances of variable nature. Chlorosis occurs chiefly among young and delicate women who lead sedentary lives under unwholesome conditions.

kwir, a body of singers organized to render music in church services. Not infrequently the term is applied to those who lead congregational singing. A choir consists of at least four voices--soprano, alto, tenor, bass. In cathedral services the choir is divided usually into two sets of voices for responsive singing, one sitting on the north, the other on the south of the chancel. For a discussion of the term used in an archtectural sense, the reader is referred to the article on CATHEDRAL.

an ancient French family which has furnished many distinguished individuals. One of the best known is Etienne François, duke of Choiseul-Amboise, born in 1719, died 1785. He entered the army in early life, and, after distinguishing himself on various occasions in the Austrian War of Succession, returned to Paris, where his intimacy with Madame de Pompadour furnished the means of gratifying his ambition. After having been ambassador at Rome, and at Vienna, where he concluded with Maria Theresa the treaty of alliance against Prussia, he became in reality prime minister of France, and was very popular through a series of able diplomatic measures. He negotiated the famous Family Compact which reunited the various members of the Bourbon family, and restored Corsica to France. His fall was brought about in 1770 by a court intrigue, supported by Madame du Barry, the new favorite of the king. He was banished to his estate, but his advice in political matters was frequently taken by Louis XVI.
