Was Caxton's contention possible? Was it true that, by the use of potassium, water could be set on fire, and that any one possessing this baneful secret could destroy the world? The plausibility with which the idea was presented, the bare directness of the style, added to its convincing power. It sounded too real to be invention, was told with too frank a simplicity to be all imagination.
The form now given by Hughes to the balance is one of so great compactness and convenience that it will probably prove a most acceptable addition to the resources of the physical laboratory. Nature. Cast iron may be hardened as follows: Heat the iron to a cherry red, then sprinkle on it cyanide of potassium and heat to a little above red, then dip.
Warm six ounces of pure rain water, and dissolve in it 2 ounces of cyanide of potassium, then add a 1/4 ounce oxide of gold; the solution will at first be yellowish, but will soon subside to white; then half fill a bottle with whiting, fill it up with this solution and shake it well; you may now take a piece of old cotton, wet it with the solution, rub it well over brass, copper, &c., and it is nicely washed with gold.
The unfertilized soil at the Rothamsted station contains, in 2,000,000 pounds corresponding to about 6-2/3 inches to the acre 1000 pounds of phosphorus and 35,000 of potassium, while an acre of plowed soil of the same weight at State College, Pennsylvania, contains 1100 pounds of phosphorus and 50,700 of potassium.
I was wearing a mask of my own invention, a thing that covered ears and head and everything, something like a diver's helmet I was dealing with gases a sniff of which meant death; only a few days before, unmasked, I had been doing some fool's trick with a couple of acids sulphuric and cyanide of potassium when, somehow, my hand slipped, and, before I knew it, minute portions of them combined.
The Salindres factory regulates the price to a certain extent, and its system of working is regarded as a guide in the various processes connected with this branch of industry. The manufacture of potassium and sodium will, it is expected, be more fully elucidated than hitherto, by means of researches made at Schering's Charlottenburg factory.
Iodine or Iodide of Potassium demands large draughts of wheat flour or starch in water, and then vinegar and water. The stomach should then be emptied by vomiting with as much tepid water as the stomach can hold. Prussic acid, a violent poison, is sometimes taken by children in eating the pits of stone fruits or bitter almonds which contain it.
Make up your mind, Lucia, to give yourself, trust yourself, to me, and I will promise to get you quite well, sooner than any doctor can. I suppose you have seen one?" "Yes." "Well, what does he do for you?" "Oh, I take hydrochloric acid, sulphuric acid, and strychnine through the day, and digitalis and potassium bromide at night." "Good heavens! Lucia! how can you be so foolish?" I exclaimed.
When cinchonine is treated with potassium hydrate, it is decomposed into quinoline and a solid body, which on further treatment yields a liquid base, C H N, which is probably lutidine. It has been found, moreover, that both tetrahydroquinoline and dihydroquinoline, hydrogen addition products of quinoline, are present.
E. a powder of bromide of potassium, amounting to 30 or even 40 grains at a time, and an average of about 100 grains per day. The value of this remedy has been a matter of much controversy some practitioners lauding it to the skies as one of the most powerful agents of control in all disorders of the nervous system, others pronouncing it entirely inert.
