The former is a salt which appears under the form of white crystals; when heated to a temperature of 400 deg. it is transformed into chlorine of potassium, and the oxygen which it contains is given off freely. Now 18 lbs. of chlorate of potash give 7 lbs of oxygen—that is to say, the quantity necessary to the travellers ...

How the plant uses these substances is yet poorly understood, but we are fairly certain that each one has some particular function in the life of the plant. ...

The world knows nothing of this Samuel Hopkins, but the potash industry, which was evidently on his mind, was quite important in his day. Potash, that is, crude potassium carbonate, useful in making soap and in the manufacture of glass, was made by leaching wood ashes and boiling down the lye. To produce a ton of potash, the trees on an acre of ground would be cut down and burned, the ashes leached, and the lye evaporated in great iron ...

... antiseptics are disinfectants even when used in strong doses. Disinfectants have no place in dairy work, except to destroy disease bacteria, or preserve milk for analytical purposes. Corrosive sublimate or potassium bichromate are most frequently used for these purposes. The so-called chemical preservatives used to "keep" milk depend for their effect on the inhibition of bacterial growth. With a substance so violently toxic as formaldehyde (known as formalin, freezene) ...

... phosphorus will not answer—and pour a little liquid air on it, stirring it gently, as you see. Now, if I should let that dry it would explode at the slightest touch; but we do not want that, and we wish to increase its power, so we add a little chloride of potassium; now watch it dry—see the color change to a light red-brown. There, if you should strike that or put fire to it, it would wreck this building as completely as if you had exploded fifty pounds of dynamite ...

Collodion made exactly as described by DR. DIAMOND in "N. & Q.," entirely answers our expectations, and we prefer it, for our own use, to any we have ever been ...

... will perhaps provoke smiles upon the countenances of those who perchance read them. In this pioneer contribution on gunpowder analysis the charcoal of the powder is often called "oxid of carbon." In referring to the separation of potassium and sodium it is recommended to precipitate out the first in the form of tartrate. Naturally, nitre itself comes in for serious thought and the explosibility of the mixture of charcoal, nitre and sulphur arrests the author's attention, ...

... poison. When, however, his evidence was sifted, it was discovered that he had only obtained traces of the poison by the distillation of the stomach with sulphuric acid. As saliva contains ferrocyanide of potassium, out of which sulphuric acid generates prussic acid, the latter substance will always be obtained by the process adopted by Professor Aiken from any stomach which has in it the least particle of saliva. If, then, the professor did really ...

Pittsburg Joe, who was Second Hall-man, used to join Rover Jack in his jags; and it was a saying of the pair that the Erie County Pen was the only place where a man could get "slopped" and not be arrested. I never knew, but I was told that bromide of potassium, gained in devious ways from the dispensary, was the dope they used. But I do know, whatever their dope was, that they got good and drunk ...

... insanity are cured now which a few years ago would have remained uncured. Indeed, in relation to the associated bodily state, it may be said that specific treatment has been adopted. Remedies, like iodide of potassium, in large doses, are employed in cases in which, from the increased attention directed in recent years to the somatic aetiology of insanity, a causal relation between the physical and mental condition has been recognized, and the mental symptoms have disappeared in the most marked manner; and ...

... its preparation is not very different from that employed even at the present time. He also suggests in his volume how alcohol may be obtained in high strengths. He distilled the spirit obtained from wine over carbonate of potassium, and thus succeeded in depriving it of a great proportion of its water. We have said that he was deeply interested in the philosopher's stone. Naturally this turned his attention to the study of metals, and so it is not surprising to find that he succeeded in formulating ...

... look on the back of the spoon, you will perhaps see "Rogers Bros. 1846." These men were the first silvermakers in this country to plate tableware by electricity. To make a spoon, they formed one out of iron or copper and made sure that it was perfectly clean. Then across a bath of silver cyanide, potassium cyanide, and water they laid two metal rods, and from these they hung a spoon at one end and a plate of silver at the other. These rods were connected with the two poles of a battery. The electrical current ...

The earthy substances in cotton are also of importance. These are potassium carbonate, chloride, and sulphate, with similar sodium salts, and these vary in different samples of cotton, and possibly influence its properties to some extent. Then there are oily matters in the young fiber which, upon its ripening, become ...
