In the composition of vital tissues we constantly find these basal elements: Carbon, oxygen, hydrogen, nitrogen, sulphur, phosphorus, chlorine, potassium, sodium, magnesium, calcium, iron, manganese, fluorine, silicon, and iodine. The function of these elements will be ...

... his report to the Association of Official Agricultural Chemists for the year 1913, stated that the method giving the most uniform results was that of ashing the beer with an excess of standard calcium acetate, and that while the moist combustion method in the hands of those familiar with it gave satisfactory results, the various collaborators working with the method did not get as uniform results as with the method of ashing with calcium ...

... Edward B. Acheson, a graduate of the Edison laboratories. Acheson, in 1891, was trying to make artificial diamonds and produced instead the more useful carborundum, as well as the Acheson graphite, which at once found its place in industry. Another valuable product of the electric furnace was the calcium carbide first produced in 1892 by Thomas L. Wilson of Spray, North Carolina. This calcium carbide is the basis of acetylene gas, a powerful illuminant, and it is widely used in metallurgy, for welding ...

... agents recommended to substitute the sulphydrates have proved available. Of these the author mentions ferrous chloride (6), ferrous chloride in alcohol (7), formaldehyde (8), sulphocarbonates. The different sulphydrates (9) have very different effects. The calcium compound tends to harden and weaken the thread. The ammonia compound requires great care and is costly. The magnesium compound works rapidly and gives the strongest thread. Investigations have established the following point. In practice it is not ...

Broadly speaking, the plant cell behaves in a similar way. The manifestation of each form, which is inherent as a potentiality in the specific structure, is ultimately to be referred to ...

So locally intense indeed was the heat within a certain zone, that all the oxygen contained in the mixture was expelled and alloys of iron, aluminum, and calcium combined with more or less silicon, and phosphorus were produced. Some of these were of an ...

You have seen when the shell bursts how the chalky soil of the Marne effervesces like the inkwells at school, when we used to throw a piece of calcium carbonate into them. Well, it was almost like that, but in the midst of the desert, in the midst of obscurity. The white waters rushed into the depths of the black hole, and rose and rose towards the pedestal on which we stood. And there was the uninterrupted noise of thunder, ...

It is proposed, in case of attack, to illuminate the Erie Palace by means of Colonel FISK'S big diamond, which, it is estimated, would prove more powerful than a dozen calcium lights. If this should not be dazzling enough, it is suggested that a glimpse of the Colonel's $5,000 uniform might have the desired effect. Amongst the novel instruments of warfare which the contest has given birth to, is a new ball projected by the Prince of Erie. It will be given at Long Branch, ...

... to the maintenance of a higher organic life, is found in the deposits of lime. My readers will excuse me, if I introduce here a very elementary chemical fact to explain this statement. Limestone is carbonate of calcium. Calcium is a metal, fusible as such, and, forming a part of the melted masses within the earth, it was thrown out with the eruptions of Plutonic rocks. Brought to the air, it would appropriate a certain amount of oxygen, and ...

... are familiar with glass making may receive some help at this point by remembering that the various glasses are silicates, for they are made by melting sand (which is nearly pure oxide of silicon) with various metallic oxides. With lime (calcium oxide) and soda (which yields sodium oxide) we get soda-lime glass (common window glass). Lead oxide being added to the mixture a dense, very brilliant, but soft glass (flint glass) results. Cut glass dishes and "paste" gems are made of this flint glass. Now the glasses, ...

... very remarkable that the fossil ivory of the mammoth, and specimens of the historic period of Pompeii or Egypt, contain sometimes as much as 10 per cent. more of fluoride of calcium than the ivory of the present day. We apprehend, however, that this property—first investigated by Dr George Wilson—may be derived from long-continued contact with earth, since fluoride of calcium is the chief ingredient in the enamel or exterior portion of the tooth.

Inventors had to wait till science had given us in abundance a metal less than a quarter the weight of iron, but as strong and durable, and this was not until some fifty years ago when a process was discovered for producing cheaply the beautiful metal calcium. But calcium would have been little use alone. Aluminium, which is now so plentiful, had to be alloyed with it, and aluminium was not used to any great extent till the beginning of this century, when an electric process ...

The increasing fame of Hawthorne has been like a calcium-light, illuminating for the past fifty years everything to which that name attaches, and leaving the Manning family in a shadow so much the deeper. All we can learn of them now is, that they were descended from Richard Manning, of Dartmouth in Devonshire, England, ...
