Another objection to the use of litmus is that the degree of acidity is not accurately indicated, and therefore the farmer is sometimes at a loss to know just how much lime should be applied to make soil conditions favorable for growing crops. A More Accurate Method. Within the last few years improved methods for determining the presence of acidity in soil have been developed.
In the building and maintaining of the body, mineral salts serve three purposes to give rigidity and permanence to the skeleton, to form an essential element of active tissue, and to provide the required alkalinity or acidity for the digestive juices and other secretions. The origin and distribution of these mineral substances are of interest.
Mrs Pipchin's scale of charges being high, however, to all who could afford to pay, and Mrs Pipchin very seldom sweetening the equable acidity of her nature in favour of anybody, she was held to be an old 'lady of remarkable firmness, who was quite scientific in her knowledge of the childish character. On this reputation, and on the broken heart of Mr Pipchin, she had contrived, taking one year with another, to eke out a tolerable sufficient living since her husband's demise.
I had to listen to him, and he had to pay me for listening. I've no doubt his general yearly expenditure has been increased for the same reason eh, Maitre Fille? He has done it with others yes?" M. Fille waved a hand in deprecation, and his voice had a little acidity as he replied: "Ah, monsieur, what can we poor provincials do any of us in dealing with men like you, philosophy or no philosophy?
Biles rigged the sucker in the pump, toned up a few cans of milk, corrected the acidity, and went into the house to receipt the judge's bill. Mr. Biles' theory interested the judge, but the argument did not convince him. And so the judge resolved to buy a cow and obtain pure milk, without regard for the alleged views of Professor Huxley.
Now it complained simply because it was badly fed, and it made Pelle quite furious to see the nasty trash that was thrown to it a young pig must eat well, that is half the battle. They ought not to go running out every few minute to throw something or other to the pig; when once the heat really set in it would get acidity of the stomach. But there was no sense in these town folk.
I have seen an analysis reporting half a per cent. of calcium oxid, which would make five tons of quick lime in the plowed soil of an acre; whereas the soil not only contained no lime whatever, but was so acid that it needed five tons of ground limestone per acre to correct the acidity.
"Not in the sense of containing injurious alkali, like sodium carbonate, the compound which is found in the 'black alkali' lands of the arid regions of the far West; but chemically considered limestone is truly an alkali; and, as such, it has power to neutralze this soil acidity." "Is the acidity harmful to the crops?"
His urbanity was unimpaired, but he permitted himself a slight acidity of tone as he retorted with gentle malice "Well, you can't help the colour of your hair. So I'll keep my nerve." "I didn't expect to be insulted!" cried Rachel, flushing far redder than that rich hair of hers, and paced pompously out of the room, her face working violently. The door was ajar. She passed Mrs.
Sometimes, when the bitter element is refined away, the black part assumes an acidity which takes the place of the bitterness; at other times the bitterness being tinged with blood has a redder colour; and this, when mixed with black, takes the hue of grass; and again, an auburn colour mingles with the bitter matter when new flesh is decomposed by the fire which surrounds the internal flame; to all which symptoms some physician perhaps, or rather some philosopher, who had the power of seeing in many dissimilar things one nature deserving of a name, has assigned the common name of bile.
