GUNPOWDER. Reduce to powder separately, five drams of nitrate of potass, one dram of sulphur, and one of new-burnt charcoal. Mix them together in a mortar with a little water, so as to make the compound into a dough, which roll out into round pieces of the thickness of a pin, upon a slab. This must be done by moving a board backwards and forwards until the dough is of a proper size.
Take of linseed oil 2-1/2 galls., spirits of turpentine 2-1/2 galls., western petroleum 1 gall., liquor potass 8 oz., sap green 1 oz., mix all together, and it is ready for use. Take of aloes, 3 oz.; anise seed, 3 oz.; pulverise and mix with castile soap. This makes one ball for a horse.
"With this we must save you and your daughter from the half-breeds," said the trapper, a little impatient at this ill-timed manifestation of pedantry. "Get ready for action immediately." "I have no oxygen gas." "Make it at once," said Edwards. He picked up some papers marked "chlor. potass." and "black oxide." "Here is your material," he said. "Do you understand chemistry?" asked Lindsley.
10 grams of nitrate of silver are dissolved in 50 grams of distilled water; then 25 grams of cyanide of potassium in 50 grams of distilled water; the two liquids are mixed in a decanter, and stirred for 10 minutes; it is then filtered. Finally, 100 grams of sifted whiting are mixed with 10 grams of pulverised supertartrate of potass and one gram of mercury.
It would have been strange, after all, he thought, if he had not been able to hoodwink poor old Durrance; and he returned to the smoking-room and refreshed himself with a whiskey and potass. Durrance, however, had not been hoodwinked. The last perplexing question had been answered for him that afternoon.
Bromide of Potassium Is prepared by mixing bromine and a solution of pure potass together, and evaporating to dryness; it crystallizes in small cubes, and dissolves readily in water. This agent is extensively employed in the paper and glass processes. Bromide of Lime. This the principal accelerator used in the American practice, and is the best of all dry combinations at present employed.
Tolbridge, and at your doorstep I have shaken the dust from my skirts and my feet." And with a quick step and a high head, she marched out of the room. The doctor took a little book out of his pocket, and on a blank leaf wrote the following: Rx. Potass. Bromid. 3iij Tr. Dig. Natis. m. xxx Tr. Lavand. Comp. ad 3iij M.S. teaspoonful every three hours.
Our ashes produced a potass of fine colour, and we did not doubt of succeeding, when we should have sent a sample of it to France. We made about four barrels, and my father sent a box of it to a friend of his at Paris to analyze. Whilst waiting the reply of the chemist, he hired three negroes to begin the cultivation of his island of Safal.
Some days after this jaunt, my father endeavoured to find whether the plants with which the island was covered would be useful in making potass. He arranged with a person in Senegal to hire for him some negroes, and a canoe to gather the ashes of the plants after they were burned.
It is, however, always wise to call in medical advice in order to settle this important question, and the more so, since there is one remedy, the chlorate of potass, which, in appropriate doses, acts upon the condition almost as a charm.
