The presumption is either that d 2 V/dh 2 near the ground is much larger numerically than Gerdien supposes, or else that the ordinary instruments for measuring ionization fail to catch some species of Ion Whose Charge Is Preponderatingly Negative.
The charge on an ion being 3.4 X 1010 Mache deduces for the ionic charge, I + or I_, per cubic metre 1800X3'4 X 10 -1 ° X Io 6, or o 6.
The " children of Ion " originated in north-eastern Peloponnese; and traces of them remained in Troezen and Cynuria.
Most Ionian states exhibit also traces of the fourfold tribal divisions named after the " children of Ion "; but additional tribes occur locally.
The minority, among whom were prominent Ca" "pals Rauscher and Schwarzenberg, Hefele, bishop of Rotterdam (the historian of the councils) Cardinal Mathieu, Mgr Dupanloup, Mgr Maret, &c., &c., did not pretend to deny the papal infallibility; they pleaded the inopportuneness of the definition and brought forward difficulties mainly of an historical order, in particular the famous condemn ion of Pope Honorius by the 6th ecumenical council of Const: ntinople in 680.
Plutarch (Pericles) gives many interesting details as to Pericles' personal bearing, home life, and patronage of art, literature and philosophy, derived in part from the old comic poets, Aristophanes, Cratinus, Eupolis, Hermippus, Plato and Teleclides; in part from the contemporary memoirs of Stesimbrotus and Ion of Chios.
The following passage is especially instructive: " Et tant s'en Taut que je veuille que ion croie toutes les choses que j'ecrirai, que meme je pretends en proposer ici quelques-unes que je crois absolument titre fausses; A savoir, je ne doute point que le monde n'ait etc cree au commencement avec autant de perfection qu'il en a; en sorte que le soleil, la terre, la lune, et les etoiles ont etc des lors; et que la terre n'a pas eu seulement en soi les semences des plantes, mais que les plantes meme en ont couvert une partie; et qu'Adam et Eve n'ont pas etc crees enfans mais en Age d'hommes parfaits.

The result of this is that the alkalinity of the sea-water increases and the hydrogen-ion concentration decreases.
Experiments made by Moore and Whitley at Port Erin in the Isle of Man show that the hydrogen-ion concentration falls from about 1084 in Dec. to about 108 ' 4 in April.
Evaporation of the water and anything that lowers the hydrogen-ion concentration have the same effect.
Denitrifying bacteria will raise the alkalinity (or reduce the H-ion concentration) by forming ammonia, which will combine with the carbonic acid in solution and so throw down normal carbonate of lime.
Taking the chemical equivalent weight of silver, as determined by chemical experiments, to be 107.92, the result described gives as the electrochemical equivalent of an ion of unit chemical equivalent the value 1 036 X 5.
Thus, as long as every ion of the solution is present in the layer of liquid next the electrode, the one which responds to the least electromotive force will alone be set free.
When the amount of this ion in the surface layer becomes too small to carry all the current across the junction, other ions must also be used, and either they or their secondary products will appear also at the electrode.
Here the ions are potassium and the group Ag(CN)2.1 Each potassium ion as it reaches the cathode precipitates silver by reacting with the solution in accordance with the chemical equation K--+KAg(CN) 2 =2KCN+Ag, while the anion Ag(CN) 2 dissolves an atom of silver from the anode, and re-forms the complex cyanide KAg(CN) 2 by combining with the 2KCN produced in the reaction described in the equation.
But if one ion, say the anion, travels faster through the liquid than the other, the end of the solution from which it comes will be more exhausted of salt than the end towards which it goes.
On the right, towards which the faster ion travels, five molecules of salt are left, being a loss of two from the original seven.
If either ion carried with it some of the unaltered salt or some of the solvent, concentration or dilution of the liquid would be produced where the ion was liberated.
Hence the absolute velocities of the two ions can be determined, and we can calculate the actual speed with which a certain ion moves through a given liquid under the action of a given potential gradient or electromotive force.
A series of equivalent solutions all containing the same coloured ion have absorption spectra which, when photographed, show identical absorption bands of equal intensity.
If an element be present in a compound otherwise than as an ion, it is not interchangeable, and cannot be recognized by the usual tests.
(See Arrhenius, loc. cit.) The simplest and most important case is that of two electrolytes having one ion in common, such as two acids.
The heat of formation of a substance from its ions is, of course, very different from that evolved when it is formed from its elements in the usual way, since the energy associated with an ion is different from that possessed by the atoms of the element in their normal state.
The ions will therefore diffuse independently, and the faster ion will travel quicker into pure water in contact with a solution.
The ions carry their charges with them, and, as a matter of fact, it is found that water in contact with a solution takes with respect to it a positive or negative potential, according as the positive or negative ion travels the faster.
In gases the electrons sometimes travel alone, but in liquids they are always attached to matter, and their motion involves the movement of chemical atoms or groups of atoms. An atom with an extra corpuscle is a univalent negative ion, an atom with one corpuscle detached is a univalent positive ion.
ION, of Chios, Greek poet, lived in the age of Pericles.
For simplicity of calculation, the clear length of each rod between the yokes is made 12.56 (=47r) centimetres, while the coil surrounding the standard bar contains 100 turns; hence the magnetizing force due to a current of n amperes will be ion C.G.S.
It is apparent that metallic salts of organic acids would, in aqueous solution, be ionized, the positive ion being the metal, and the negative ion the acid residue.
In the diagrammatic family tree of the Greek people, as it appears in the Hesiodic catalogue (6th century) and in Hellanicus (5th century), the " sons of Hellen " are Dorus, Xuthus (father of Ion and Achaeus) and Aeolus.
It is still surrounded by a double wall partly in ruins, and amongst the remains are a "patriarchal" church finished in Ion), two other churches, both of the 11th century, a fourth built in 1215, and a palace of large size.
The priest of Shiloh is a much greater person than Micah's priest Jonathan; at the great This appears even in the words used as synonyms for " priest" rnvn, p ion 'Dr, which exactly corresponds to sadin and hajib.

To King George and his ministry, Massachusetts was the hotbed of disloyalty, the head and front of opposi t ion to their colonial policy, and there coercion should p y?
It may indeed be said that the Constitut ion as it now stands is the result of a long process of development; and that process is still going on.
On the lines of Poynting's theory of solution, each ion in electrolytes must combine with one or more molecules of solvent.
Since some ions are more mobile than others, a separation will ensue when water is placed in contact with a solution, the faster moving ion penetrating quicker into the water under the driving force of the osmotic pressure gradient.
He seized the occasion to ~ make his peace with Liberal sentiment, and the bill ion, of indemnity for past ministerial breaches of the constitution was carried in the new Prussian diet with enthusiasm.

Whenever Ion freeholders request it, the county commissioners must submit to the voters of a proposed high school district the question of establishing a high school district, and each precinct giving a majority vote for it constitutes a part of such a district for establishing and maintaining a high school.
He was a pupil of Anaxagoras, and is said by Ion of Chios (ap. Diog.
Thomson, the successor of Maxwell and Lord Rayleigh in the Cavendish chair of physics in the university of Cambridge, began about the year 1899 a remarkable series of investigations on the cathode discharge, which finally enabled him to make a measurement of the ratio of the electric charge to the mass of the particles of matter projected from the cathode, and to show that this electric charge was identical with the atomic electric charge carried by a hydrogen ion in the act of electrolysis, but that the mass of the cathode particles, or " corpuscles " as he called them, was far less, viz.
The subject was pursued by Thomson and the Cambridge physicists with great mathematical and experimental ability, and finally the conclusion was reached that in a high vacuum tube the electric charge is carried by particles which have a mass only a fraction, as above mentioned, of that of the hydrogen atom, but which carry a charge equal to the unit electric charge of the hydrogen ion as found by electrochemical researches.
Plural adjectives are formed from the singular by i-affection or by adding the termination -ion or -on; thus hardd, " beautiful," pl.
Distrusting tradition, he took a few of the finest dialogues as his standard, and from internal evidence denounced as spurious not only those which are generally admitted to be so (Epinomis, Minos, Theages, Arastae, Clitophon, Hipparchus, Eryxias, Letters and Definitions), but also the Meno, Euthydemus, Charmides, Lysis, Laches, First and Second Alcibiades, Hippias Major and Minor, Ion, Euthyphro, Apology, Crito, and even (against Aristotle's explicit assertion) The Laws.
After the fire of 1 184 the monks asserted that they were in possession of the remains of St Dunstan, which had been abstracted from Canterbury after the Danish sack of ion and kept in concealment ever since.
