But we have permanganate and a syringe both, and we know what to do with them." "Good. But be careful where you step. What do you wear on your feet?" He examined the boys' shoes and canvas leggings. "They're all right. I don't believe any snake will bite through them. But high leather boots would be safer. Bear it in mind when you buy new shoes. Now I must go."
Long-drawn exclamations of "Eigh! Eigh!" greeted this magic, performed by means of permanganate crystals held between the fingers. "With this bathe the wounds of your steer. Then sprinkle the remainder over your cattle.
His wife disinfected plates, forks, spoons, and even the fruit, in a weak solution of permanganate of potassium. Of course there must be no alcoholic excesses. In the tropics it is also essential, for several reasons, always to boil the drinking water. The Dutch use an effective cholera essence, and if the remedy is applied immediately the chances for recovery from the attack are favourable.
Hands usually clenched; feet arched and inverted. Congestion of brain, spinal cord, and lungs. Treatment. Emetics or stomach-pump if the patient is deeply anæsthetized. Tannic acid and permanganate of potassium. Bromide of potassium 1/2 ounce with chloral 30 grains, repeated if necessary. Quarter of a grain. Ten minutes; usually two to four hours. Method of Extraction from the Stomach.
Weigh out about 0.2 gram in excess of this quantity of !pure! oxalic acid into the corresponding beakers, weighing the acid accurately and recording the weight in the notebook. If a residue remains which is sufficiently colored to obscure the end-reaction of the permanganate, it must be removed by filtration.
!Method B! !Oxalate Standards! PROCEDURE. Weigh out two portions of pure sodium oxalate of 0.25-0.3 gram each into beakers of about 600 cc. capacity. Make a blank test with 20 cc. of manganous sulphate solution and a volume of distilled water equal to that of the titrated solution to determine the volume of the permanganate solution required to produce a very slight pink.
Two figures met him, the dark-eyed Miss Drake, all in white, and behind her a shuffling, grinning native woman, who carried a basin, in which permanganate of potash swam gleaming like diluted blood. "Good-morning."
But the poison had not all been sucked from the wounds or counteracted in the veins by the permanganate. Before the girl could again twist tight the tourniquet he sank down for the second time, unconscious.
It is also possible to replace the hydrochloric acid by evaporating the solutions with an excess of sulphuric acid until the latter fumes. This procedure is somewhat more time-consuming, but the end-point of the permanganate titration is more permanent. Both procedures are described below.
The solution has so deep a color that the lower line of the meniscus cannot be detected; readings must therefore be made from the upper edge. Run out into a beaker about 40 cc. of the ferrous solution, dilute to about 100 cc., add 10 cc. of dilute sulphuric acid, and run in the permanganate solution to a slight permanent pink.
