He had written an article in Le Temps, and drawn public interest to his theory that iodine could be made from benzine.
From sulphur he turned to iodine as a subject of original experimentation, and then, oblivious of Aristotle's injunctions, to the goldmaker's art.
The colour which iodized collodion assumes on keeping, I consider to be entirely due to the gradual separation of iodine from the iodide of potassium or ammonium originally introduced.
The monovalent iodine, for instance, is transformed by heating into an allotropic form, corresponding to the formula I, whereas ordinary iodine answers to I2.
CH2I, the atoms of iodine being removed from two molecules of propyl iodide, with the resulting fusion of the two systems of three carbon atoms into a chain of six carbon atoms.
Iodine 12 grains, lard or spermaceti ointment half an ounce, makes a capital ointment for bunions.
Free applications of arnica or iodine will have an excellent effect.
A far-sighted person would have foreseen other results from the mixture beside the chemical action of the iodine on the starch.
There was iodine in the house and there was starch.
The fifth in iodine is slightly rearranged to form the fourth in descent in gold, and the remaining two are the same.
The central globe follows boron, save that it has a septet for its centre; this was figured in iodine (p.
Four of the first ring in the iodine funnel are replaced by the triangular body, which becomes a four-sided pyramid with an occupied base.
The twelve septets of c assume the form of prisms as iniodine (see p.
Illustration] Iodine has nothing new to give us, except five similar ovoid bodies at the top of each funnel, and two quartets instead of two pairs in the central globe.
The g groups are identical with those in gold, but difference of pressure makes the containing body spherical instead of ovoid; similar groups are seen in the top ring of the iodine funnel, where also the "hole" is ovoid in form.
The second ring of three ovoids in iodine becomes four in gold, but the internal arrangement of each ovoid is the same.
It will be seen that, complex as gold is, it is composed of constituents already familiar, and hasiodine and occultum as its nearest allies.
The next two spheres in the iodine funnel coalesce into one sphere, with similar contents, in the gold funnel.
Nitric acid reacts energetically with it, but without incandescence, and a certain amount of iodine is liberated.
When heated to low redness it decomposes into free iodine and phosphide of boron, BP.
Crystals of iodine dissolve instantly in contact with it, with evolution of a gas and considerable rise of temperature.
Compounds of boron, phosphorus, andiodine recently prepared by M.
While he was putting iodine in the cut I felt in Westy's pocket like Doc told me to do, but there wasn't any knife there.
Give me the iodine and some bandage, one of you fellows.
An aqueous solution of iodine and potassium iodide shaken with chloroform gives similar results, and the difference in color between the two layers is an advantage for a lecture experiment.
A iodide having more than one atom of iodine in the molecule.
An iodide containing a higher proportion of iodine than any other iodide of the same substance or series.
When the spores are fully developed, the sporophores wither, and if a solution of iodine be applied, which changes the spores to a rich brown, they will be seen still adhering by their spicules to the faded sporophores.
When the sporidia are very delicate and hyaline, the septa cannot readily be seen if present; to aid in the examination, a drop of tincture of iodine will be of considerable advantage.
The iodide of silver in like manner is changed into a sub-iodide; but with water hydriodic acid is formed unless an iodine absorbent be present--then into hypoiodic acid.
Under these circumstances the iodine and carbonate of soda give a precipitate of iodoform exactly similar to that obtained by treating natural waters.
The latter is now removed, and to its liquid contents, there is added a small quantity of iodine and carbonate of soda.
The formation of iodoform by precipitation under the action of iodine and carbonate of soda is a very sensitive test for alcohol.
This is the case in the methods for staining the tubercle bacillus and also in Gram's method, the essential point in which latter is the treatment with a solution of iodine before decolorizing.
In some cases the spore-forming protoplasm gives a blue reaction withiodine solutions.
In other forms a substance (probably glycogen or amylo-dextrin) which turns brown with iodine has been observed.
The occurrence of a starch-like substance which stains deep blue with iodine has been clearly shown in some forms even where the bacterium is growing on a medium containing no starch, as shown by Ward and others.
In each of a number of experiments he found that the weight of the silver iodide did not differ by one twenty-thousandth of the whole from the sum of the weights of the silver and the iodine used.
His opponent would be disposed to say that the iodine and the mercury ceased to exist when the red powder was formed, that they were components but not constituents of it.
Stas, in his syntheses of silver iodide, weighed the silver and the iodine separately, and after converting them into the compound he weighed this also.
The atomist has an easy answer; he says that the new body is made up by the juxtaposition of the atoms of iodine and mercury, which still exist in the red powder.
The others suffered the sting of the iodine without a word, walking off when they were bandaged, or carried by our sanitars on the stretchers, still with that look of wonder and trust in their eyes.
These substances were mainly iodine and bromine, two chemical elements that are of greater value than the nitrates themselves.
From this port about fifty million dollars' worth of nitrates and three million dollars' worth of iodine are exported yearly.
Add a little more iodine from time to time, until the zinc is nearly all dissolved.
He had seven bites on one ankle and two on the other, and the resulting wounds were swollen and suppurating, but by the application of iodine followed by hot compress bandages, he was able to resume his work in three days.
In front of the aperture were placed a plate of transparent rock-salt, and a flat cell of thin glass containing a solution of iodine in carbon bisulphide.
Owing to the inflammable nature of carbon bisulphide, the plate of rock-salt was found to be hardly a sufficient protection, and Tyndall surrounded the iodine cell with an annular vessel through which cold water was made to flow.
Cobalt dioxide, CoO2, has not yet been isolated in the pure state; it is probably formed when iodine and caustic soda are added to a solution of a cobaltous salt.
Winkler, by the analysis of the chloride, and by the action of iodine on the metal, obtained the values 59.
The iodide, CoI2, is produced by heating cobalt and iodine together, and forms a greyish-green mass which dissolves readily in water forming a red solution.
In case the fluid is neutral, but more or less colored and odoriferous, and iodides or bromides are detected, we may justly suspect that the poisoning has been caused by the reception of iodine or bromine.
Lassaigne--to expose the paper to the action of iodine vapors.
For this purpose, a small portion is moistened with a little water, a few drops of iodine solution added, and the mixture placed on the side of the microscope: the bluish grains contained in the polyhedral and cellular envelope (Fig.
The addition ofiodine causes the potato starch granules to acquire a blue color, and renders their shape and volume more easily perceptible; thus allowing the two varieties of starch to be readily distinguished.
In case iodine is also contained in the fluid, and the detection of bromine is desired, it is necessary to acidulate the solution with hydrochloric acid, and then shake it with chloride of lime and bisulphide of carbon.
In case iodine has not been detected, chlorine water and ether are added to a second portion of the fluid, and the mixture well agitated.
A column of carbonate of soda is then introduced above the precipitate for the purpose of retaining the excess of iodine probably taken.
The isolation of the iodinehaving been effected, it remains to be ascertained that it imparts a blue color to starch paste, and a violet color to bisulphide of carbon.
There is no hot water, no sterilising, no cyanide gauze even, but iodine saves many lives, and we have plenty of it.
He did not even limp, so he was spared the ordeal of having the stinging iodine poured on the wounded leg.
If the skin is not penetrated, but scratched only, applyiodine and a sterile or wet dressing.
Iodine might have been recognised as an elementary body; but its relations to oxygen and hydrogen would probably have remained unknown, had not a knowledge of the true character of chlorine assisted the enquiry.
The vapour of iodine had a less distinct, but still a very sensible action.
In his memoir "On a solid compound ofIodine and Oxygen," he enumerates, amongst the agencies of that body, its singular property of forming crystalline combinations with all the fluid or solid acids.

During this winter he was engaged in an elaborate enquiry into the composition of ancient colours; and also in experiments upon certain compounds of iodine and of chlorine.
Having pointed out the channel through which Iodine first fell into the hands of Davy, let us pursue its history.
Clement, formed the same opinion, and maintained it, when I first stated to him my belief that it was a new and peculiar acid, and that Iodine was a substance analogous in its chemical relations to Chlorine.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "iodine" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: alcohol; antiseptic; iodine; silver
