Take 2 fl. ounces of muriatic acid, add zinc till bubbles cease to rise, add 1/2 a teaspoonful of sal-ammoniac and 2 ounces of water. Damp the part you wish to solder with this fluid, lay on a small piece of lead, and with a piece of hot iron or soldering iron solder the part. Take of pewter 4 parts, tin 1 part, bismuth 1 part; melt them together. Resin is used with this solder.
The moment it becomes so by the removal of the patients into another, the walls are whitewashed, and the air is purified by the fumigation with muriatic acid, according to the plan first proposed by GUYTON-MORVEAU. This operation is alternately performed in each ward in succession; that which has been the longest occupied being purified the first, and left empty till it is again wanted.
Then there is something made by the burning of the candle that changes the color of the lime-water. That is a gas, too, and you can collect it, and examine it. It is to be got from several things, and is a part of all chalk, marble, and the shells of eggs or of shell-fish. The easiest way to make it is by pouring muriatic or sulphuric acid on chalk or marble.
Daubeny of decomposition of trachytic rocks by sulphureted hydrogen and muriatic acid gases in the Solfatara, near Naples. In all these instances it is clear that the gaseous fluids must have made their way through vast thicknesses of porous or fissured rocks, and their modifying influence may spread through the crust for thousands of yards in thickness.
Aqua Regia is a compound menstruum invented by the alchemists for dissolving gold. These materials are not properly oxidized; it nearly causes their combination with chlorine, which is in the Muriatic acid. This acid forms a valuable addition to the chemicals employed by the practical Daguerreotypist.
I wish I had bought a hundred-weight, for they tell me it is worth three pound ten here." "May we inspect these specimens?" "Why not, sir? I'll trust it with you. I wouldn't with everybody, though." The partners retired with the gold, tested it with muriatic acid, weighed it, and after a short, excited interview one of them brought it back and asked with great nonchalance the price of the land.
Stir the liquor twice a day for a fortnight, or the shrub will be spoiled. SICK ROOMS. To purify sick rooms from noxious vapours, exhalations, and all kinds of infected air, put half an ounce of finely pulverized black oxide of manganese into a saucer, and pour upon it nearly an ounce of muriatic acid.
The specific gravity of it, according to Malte Brun, is 1.211, that of fresh water being 1.000. It is perfectly transparent. The applications of tests, or reagents, prove that it contains the muriatic and sulphuric acids. There is no alumina in it, nor does it appear that it is saturated with marine salt or muriate of soda.
Some hydrochloric, or, as it is generally called, muriatic acid, is poured upon it to the depth of about three quarters of an inch; the tube is then placed in some boiling water heated over a lamp in a tinned or other vessel, and allowed to boil for from ten to fifteen minutes; the tube is then removed and its contents allowed to cool, and then examined.
This will account for the long description of the cyanuret of potassium, while the preparation of the equally important and even more used acids, the sulphuric, muriatic, etc., commonly found in commerce, are altogether neglected.
