I have here a cylindrical glass jar in which I place some sal-ammoniac and quicklime. I will wet it and heat it a little. That produces the pungent gas of ammonia. "On one side of this third piece of paper I myself write with this mercurous nitrate solution. You see, I leave no mark on the paper as I write. I fold it up and drop it into the jar and in a few seconds withdraw it.
If you are treating the plate with nitrate of silver prepared as already mentioned, clean the plate with dilute nitric acid, rub the surface with the ball of amalgam, following with the swab and fairly rubbing in. It will be well to prepare the plate some days before requiring to use it, as a better adhesion of the silver and copper takes place than if mercury is applied at once.
They know what they are doing. They are appealing to the detestable old superstitious presumption in favor of whatever is nauseous and noxious as being good for the sick. Again, we all occasionally meet persons stained with nitrate of silver, given for epilepsy. Read what Dr.
The Lamarre compositions are all formed of a combustible substance, such as boiled oil, of a substance that burns, such as chlorate of potash, and of various coloring salts. The white composition used for charging fire balls and 1½ inch flambeaux is formed of 500 parts of powdered chlorate of potash, 1,500 of nitrate of baryta, 120 of light wood charcoal, and 250 of boiled oil.
When a corroding sore of this nature attacks the edges of the ear, and refuses to yield to the application of a few stimulating washes, such as sulphate of copper, alum, borax, nitrate of silver, &c., the diseased edges may be paired off, and the actual cautery applied to the parts. This will frequently arrest its further progress.
One pound of Glauber's salts in a drench is to be preferred. Rest in a darkened stall is indicated. An eye lotion containing three grains of silver nitrate in one ounce of distilled water should be applied to the eye three times daily. A water solution of atropine or eserine should be used for the purpose of relieving the symptoms of iritis or glaucoma. A very light diet should be fed.
Solutions of nitrate of silver are not carried about and decanted into baths and back again into bottles without tracking their path on persons and things. The photophobia of the "sensitized" plate, of course, requires a dark apartment of some kind: commonly a folding tent is made to answer the purpose in photographic excursions.
'Here's the medicine, mother, said Rose eagerly. She was flushed with running. 'It's chloric ether and nitrate of potash, a highly diffusible stimulant. And there's a chance that sooner or later it may put him into a perspiration. But it will be worse than useless if the hot applications aren't kept up, the doctor said. You must raise his head and give it him in a spoon in very small doses.
Development of other methods show that nitrates can probably be produced at less cost than by the use of hydroelectric power. Extensive investigation made by the Department of War indicates that the nitrate plants on this project are of little value for national defense and can probably be disposed of within two years. The oxidation part of the plants, however, should be retained indefinitely.
To those already mentioned, I should like to add the names of Hopkinson and Brinsmead in England; Bechstein and Bluthner in Germany; all well-known makers. By HENRY A. MOTT, JR., Ph.D., etc. This salt is an article of commerce, and is used technically and medicinally. Nitrate of silver possesses an acrid metallic taste and acts as a violent poison.
