TO DETECT ALKALIES IN NITRATE OF SILVER Stolba recommends the salt to be dissolved in the smallest quantity of water, and to add to the filtered solution hydrofluosilicic acid, drop by drop. Should a turbidity appear an alkaline salt is present.
The plant receives, by means of this water, at the time of its first development, the alkalies, alkaline earths, and phosphates, necessary to its organization. If these elements, which are necessary previous to its assimilation of atmospheric nourishment, be absent, its growth is retarded.
If by our various inductions we have been able to proceed no further than to such propositions as these, a a mark of b, or a and b marks of one another, c a mark of d, or c and d marks of one another, without any thing to connect a or b with c or d; we have a science of detached and mutually independent generalizations, such as these, that acids redden vegetable blues, and that alkalies color them green; from neither of which propositions could we, directly or indirectly, infer the other: and a science, so far as it is composed of such propositions, is purely experimental.
"I see what you mean," said Professor Gazen; "and, now I think of it, all the spectra we have seen belong to the group called 'metals of the alkalies and alkaline earths, which, of course, have distinctive properties." "At first, I should think the Martians would only try to attract our notice by striking spectra." "Lithium is the lightest metal known to us."
The lime, in combining with the elements of the clay, liquifies it; and, what is more remarkable, liberates the greater part of its alkalies.
They consist in great part of feldspars, which vary in composition from anorthite to andesine, or from those kinds in which there is less than one per cent of potash and soda to those in which there is more than seven per cent of these alkalies, the soda preponderating greatly.
From a careful analysis of the daily appearance of the Sun, it has been satisfactorily settled that it is completely enveloped in gas. By the application of the literary spectrum, it is also shown that this gaseous vaporization is the result of brass in a high state of incandescence, while the indications of alkalies, and, in fact, all kinds of lies, are no less distinct. Forethought.
They are then allowed to drip, and the ozokerite is ignited by the objects being held over a fire. After the ozokerite has burned away, the flame is extinguished, and the iron acquires a firmly adhering black coating, which resists atmospheric influences, as well as acids and alkalies. If the black iron vessels are to contain alkaline liquids, the above operation is repeated.
Therefore in a disease like rheumatism, which seems to be made worse by anything which increases the acidity, alkalies are obviously indicated, and it is probable that an increased alkalinity of the blood tends to prevent endocardial irritation, and may soothe an inflammation already present.
Shortness of breath, headache, drowsiness. Later, skin irritation, gastritis, jaundice, blood degeneration. Treatment. Remove from work, rest in bed, diuretics, purgatives, alkalies. Alcohol, ether, and chloroform, induce general anæsthesia, often preceded by delirious excitement, and followed by nausea and vomiting.
