The means which have proved most efficacious in decomposing these bases are the action of oxidizing and reducing agents, of bromine, of organic iodides, of concentrated acids and alkalies, and of heat.
He then passed on to other substances; to oxides and chlorides, and iodides, and salts, and sulphurets, and found them all insulators when solid, and conductors when fused. In all cases, moreover, except one and this exception he thought might be apparent only he found the passage of the current across the fused compound to be accompanied by its decomposition.
This tube must connect with the bottle containing the iodine, and the yellowish-green gas disengaged will readily combine with the iodine, forming a deep red liquid, and the operation is complete. The use of chloride of iodine will be referred to in connection with the Accelerators. Iodides.
It is found that 100 parts of iodine yield 135 parts of very white, but slightly alkaline, iodide of potassium. * I shall present the preparation of only a few iodides, and such as are more intimately connected with the Daguerreotype. Experiment.
Are we not justified in relieving their minds of needless fear and in showing them the way to prevent the dreadful sufferings of the secondary and tertiary stages brought on by suppressive drug treatment by means of mercury, the iodides, "606," etc.? These poisonous drugs suppress the initial lesion and diffuse the disease poison through the system.
The slow destruction of the affected tissue by suppuration, the absence of pain, tenderness, and redness, simulate tuberculosis, but the absence of glandular involvement helps to distinguish it. Syphilitic lesions are liable to be mistaken for actinomycosis, all the more that in both diseases improvement follows the administration of iodides.
The iodides in solution are decomposed by chlorine, iodine being precipitated, the smallest quantity of which in solution is instantly detected by its imparting to starch an intensely blue color.
Success has attended the use of a vaccine prepared from cultures of the organism; and the X-rays and radium, combined with the administration of iodides in large doses, or with intra-muscular injections of a 10
Purgatives are always more or less useful, and often required to be renewed with all the regularity of habit. Then too, the iodides, especially iodide of sodium or potassium, as recommended by M. Germain See, frequently prove of excellent service by aiding elimination and facilitating the mutations.
If the disease is localised, it may be removed by the knife or sharp spoon, and the part afterwards cauterised. As a rule, amputation well above the disease is the best line of treatment. Unlike actinomycosis, this disease does not appear to be benefited by iodides. [Illustration: FIG.
