    scrofulous glands of the neck and abdomen, and is stated occasionally to cause the wasting of even healthy glands, as the breasts and testes; it has a powerful alterative action, exhibited in its influence over scrofulous affections and secondary syphilitic disease. When given in large medicinal doses, the mucous membrane of the nose, frontal sinus, eyes, pharynx, &c., often become much irritated, and catarrhal symptoms, coryza, &c., are induced; occasionally much depression ensues from its administration, accompanied by a low febrile state of system. Iodine or iodide of potassium is administered in very many diseases, as the different forms of scrofula, in bronchocele and other glandular enlargements, in hypertrophy and induration of organs or parts produced by inflammation, as in hyper- trophy of the spleen, liver or uterus, nodes, &c.; in chronic skin affections, syphilitic or not; for the relief of other secondary or tertiary symptoms, and also in chronic rheumatism; in drop- sies as a diuretic; in some forms of amenorrhoea, as an emmen- agogue; and in various obstinate mucous discharges, as leucorrhoea, as an alterative. Externally iodine is used in chronic skin diseases and over en- larged and indurated parts and diseased joints, to alter action or cause absorption ; for this purpose it may be applied in the form of the compound tincture or ointment. As a speedy vesicant, the strong tincture may be painted over the part two or three times ; one application, however, is often sufficient. A few drops of the tincture, put into half-a-pint of hot water, may be used as an inhalation in some forms of chronic bronchitis and phthisis. Dose.

Water is often present, also iodide of cyano- gen ; besides these, fixed impurities, as plumbago, black oxide of manganese, charcoal, iron, &c. The first two are volatile; water can be detected by finding whether bibulous paper is moistened by the iodine; iodide of cyanogen by distilling at a very low temperature, when this body sublimes, if present, in white crystalline needles before the iodine; the fixed impu- rities are left after sublimation. The London Pharmacopoeia gives the following quantitative test: “ 39 grains of iodine and 9 grains of lime, dissolved in 3 ounces of water by means of a gentle heat, should give a solution of a yellow or brownish colourif the iodine be adulterated the solution is colourless, as the 9 grains of lime have the power of converting almost
