"Sulphate of iron or copper, or both together, may be dissolved in water and then neutralized with common crude potash, or its carbonate or bicarbonate known commonly as pearl ash and saleratus.
A rather amusing thing happened once when the two were together in London picking out furnishings for the house he had bought for her at Bournemouth. One afternoon they dropped in at a hotel for tea. It had been ordered by the doctors that he should have bicarbonate of soda in his tea, which it seems he did not like if he saw it put in, but if he did not see it never knew the difference.
It may be well, if sodium salicylate is being used, to give also sodium bicarbonate, the sodium bicarbonate often preventing irritation of the stomach from the sodium salicylate, the dose being equal parts of the sodium salicylate and the sodium bicarbonate administered in plenty of water.
Nourishing diet, and if there is itching, moisten the skin with five per cent. solution of aconite or solution of starch and water. BILIOUS ATTACKS. Drop doses of muriatic acid in a wine glass of water every four hours, or the following prescription: Bicarbonate of soda, one drachm; Aromatic spirits of ammonia, two drachms; Peppermint water, four ounces. Dose: Take a teaspoonful every four hours.
Serious damage may be done to the dyer by either of these classes of impurities, and I may tell you that the dissolved calcareous and magnesian impurities are the most frequent in occurrence and the most injurious. I told you that on boiling, the excess of carbonic acid holding chalk or carbonate of lime in solution as bicarbonate, is decomposed and carbonate of lime precipitated.
Feathertop led a weary life of it; for the young fry were as healthy and enterprising a brood of young ducks as ever carried saucepans on the end of their noses, and they most utterly set themselves against the doctor's prescriptions, murmured at the muriate of fleas and the bicarbonate of frogs' toes, and took every opportunity to waddle their little ways down to the mud and water which was in their near vicinity.
I did not escape it, and I am glad to tell my story about it, because it excuses some of my involuntary social shortcomings, and enables me to thank collectively all those kind members of the profession who trained all the artillery of the pharmacopoeia upon my troublesome enemy, from bicarbonate of soda and Vichy water to arsenic and dynamite. One costly contrivance, sent me by the Reverend Mr.
The administration of minimum doses of these drugs, and repeating the dose after a short interval, is preferable to large doses. Alkaline tonics are also indicated. The following mixture may be given: bicarbonate of soda, sulfate of soda and common salt, eight ounces of each, and powdered gentian and sulfate of iron, four ounces of each.
Insert the bulb of a thermometer reading to 350°C. in the bicarbonate, supporting it with a clamp so that the bulb does not rest on the bottom of the crucible. Heat the outside crucible, using a rather small flame, and raise the temperature of the bicarbonate fairly rapidly to 270°C. Then regulate the heat in such a way that the temperature rises !slowly! to 300°C. in the course of a half-hour.
This reacts with the oxalic acid, setting free carbonic acid, which, in turn, forms sodium bicarbonate with the remaining carbonate: H CO + Na CO > 2HNaCO . If, however, the solution is heated to boiling, the bicarbonate loses carbon dioxide and water, and reverts to sodium carbonate, which causes the indicator to become again pink: 2HNaCO > H O + CO + Na CO .
