It comes to this: All compounds which you can explain on your views of atomicity are atomic, and all that you cannot thus explain are molecular. Similarly with phosphates, arsenates, etc. In all these compounds it is impossible to lay one's finger on any distinction as regards chemical behavior between the compounds called atomic and those usually called molecular.
Since the war, American agriculture has suffered for want of potash and German agriculture has suffered for want of phosphates, possibly of nitrates also; because I doubt whether sufficient nitrogen is extracted from the air in Germany to provide for more than the needs of the explosive industry.
The contrast between Leonora and the rough creatures in the archway, between the flower and the phosphates which nourished it, was sharp and decisive: and Leonora, in the September sunshine, was well aware of the contrast. She felt that the loud-voiced girls were at one extremity of the scale and she at the other; and this arrangement seemed natural, necessary, inevitable.
No less than forty species of lamellibranchiate molluscs, with double valves, have been collected by Mr. Bell from the various localities of the Red Crag. At and near the base of the Red Crag is a loose bed of brown nodules, first noticed by Professor Henslow as containing a large percentage of earthy phosphates.
Just at this point my thoughts brought up hard again at the cake. No; I couldn't swallow that any better this morning than yesterday afternoon! Allow the gentleman to pay for the feast! Better to have omitted all feast; nothing simpler, and it would have been at least dignified, even if arid. What did she mean by that? And she had looked quite queer when she spoke about the phosphates.
The deposit is termed guano, and has, from time immemorial, been used by the Peruvians and Chilians as manure for the land; it is very powerful, as it contains most of the essential salts, such as ammonia, phosphates, etcetera, which are required for agriculture.
The salts are sulfates, phosphates and chlorides of sodium, potassium, calcium and magnesium. The organic and inorganic matter varies with the ration. The quantity of urine secreted within a given time varies in the different species and at different times in the same individual.
Here are gargantuan sheds, capable of holding thirty thousand tons of mineral apiece; furnaces, miniature volcanoes, for drying them artificially in winter-time, when the sun's heat is insufficient; all around you a gehenna of mad industrial life, smoke and steam, a throbbing agglomeration of wheels and belts and pistons; there are chains of buckets, filled with phosphates, wandering overhead in endless progression or disappearing sullenly into the bowels of the earth; passionate electric motors; mountains of coal and iron contrivances; railway engines snorting and whistling, or bearing a load of minerals down from the hills to where an army of Arabs will tear them out of the cars to dry, amid clouds of tawny dust.
We cannot doubt that the same result would follow if the price of the guano admitted the application of a quantity to the surface of the fields, containing as much of the phosphates as have been withdrawn from them in the same period.
If all the waste animal products could be returned to the land, Professor Van Hise says, three-fourths of the phosphorus would be replaced. All animal products are rich in phosphates. The packing houses manufacture large quantities from the bones and blood of animals. The garbage of cities, when reduced to powder, yields large returns in phosphorus.
