These 11 listings are so strange that each appears in only one of the 7 encyclopedias we compared. They include such classics as Inventory, Inverness, Inversion.

Inventory

Inversion

the chemical change which takes place when starch, dextrin, or sugar is boiled with a dilute acid. Inversion may also take place in the presence of ferments, or by prolonged iling with water. In geology, the overturning or folding over of strata by igneous agency, so that the order of their succession seems reversed. In mathematics, the operation of changing the order of the terms, so that the antecedent shall take the place of the consequent and the reverse, in both couplets. Thus, from the proportion a : b :: c: d, we have, by inversion, b: a ::d:c. In music, the transposition of certain phrases, having a common root. (1) The inversion of a chord is effected by making one of the inner notes act as a bass note, and by this means as many inversions can be made as there are actual notes in the chord, not counting the root. In such inversions the harmony remains the same, though the order of component parts is changed. (2) Intervals are inverted by making that which was the upper note the lower, and the reverse. The inversion of an interval within the octave may readily be found in the difference between the figure 9 and the interval known; then an interval of a second becomes a seventh by inversion, etc. (3) The inversion of a subject is produced by inverting the intervals of which it consists.

Involucre

or INVOLUCRUM, in botany, verticillate bracts surrounding the flowers of Umbelliferæ and Compositæ. Those surrounding the general umbel in the former order are called the universal involucre, and those around the umbrellules the partial involucre.

Involute

The curve traced by the end of a string wound upon a roller or unwound from it. This was a favorite shape for wheel teeth at one time, but was abandoned because it was found that the pressure on the pivot was increased by it, and it is now entirely superceded by the epicycloidal.

Iodic Acid

HIOs, white, crystalline solid, formed when iodine is boiled with strong nitric acid, or when sulphuric acid is added to a solution of barium iodate. Specific gravity 4. 4.629, m.p. 110° C. Soluble in water, and easily decomposed by reducing agents, forming hydriodic acid and free iodine. Used in medicine as a caustic for external application.

Iodine

i o-din, a chemical element akin to chlorine and bromine. It was obtained originally, 1811, from the ashes of a seaweed called kelp, but is now produced more cheaply from an earth abounding in the mountains of northern Chile. A ton of ashes of kelp yields about eight pounds of iodine. The name is Greek signifying "like a violet." The solid is a soft, grayish substance, but its vapor is of a beautiful deep blue. Starch is used to detect the presence of iodine, and iodine is used in many experiments and botanical examinations to detect the presence of starch. A pinch of starch dropped into a glass of water containing a millionth part of iodine turns blue at once. Tincture of iodine--iodine dissolved in alcohol--is a valuable medicine. It is an irritating poison if taken in too large a quantity. Iodine kills the microbes of certain diseases. It is peculiarly valuable as an ointment for rheumatism. It is also used in photography in the preparation of sensitive plates, and in the preparation of coal tar colors. Iodine is a nonconductor of electricity.

Iodine

in chemistry, a haloid monatomic element; symbol I; at. w. 127. Obtained from the ash of sea-weeds called kelp. In pharmacy, iodine is used externally in chronic skin diseases and over enlarged and indurated parts and diseased joints to alter action or cause absorption, or to kill parasites. It may be applied in the form of a liniment, a solution, a or an ointment. The vapor tincture iodi (vapor of iodine) may be used as an inhalation in some forms of chronic bronchitis and phthisis. A solution of iodine is useful for rendering very transparent objects more distinct.

Iodism

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. In addition, this page presents medical treatment from an era before modern medicine. The remedies described are ineffective against the conditions named, and some of the ingredients or doses are harmful. Do not use them to treat any illness; consult a qualified medical professional. This information has been left in for historical purposes but should not be acted upon. the term within which is included a variety of painful and inconvenient results following, under rare circumstances, the administration of iodine and its salts, but more especially the iodide of potash; mental depression; irritation of mucous membranes, as sneezing, watering at the eyes, etc.; a papular and postular eruption of the skin; nausea, loss of ap appetite, and a bitter taste in the mouth.
