He looked approvingly at the exquisite workmanship of an instrument where a generator of the cathode ray and an intricate maze of tubing surmounted electro-magnets and a round lead bulb.
Some cells have this property but feebly developed; but in one instance the resistance offered to the current by the anode surface was 256 times as high as that offered by the cathode surface to the same current.
The beta particles emanating from radium were soon identified with the electrons of the cathode ray.
But Roland Clewe had come to believe in the existence of a photic force, somewhat similar to the cathode ray, but of infinitely greater significance and importance to the searcher after physical truth.
In the first decade of the century it had been generally supposed that the X ray, or cathode ray, had been developed and applied to the utmost extent of its capability.
At the cathode the Cu^{++} ions are discharged and plate out as metallic copper.
It should be noted that, in general, the changes occurring at the cathode are reductions, while those at the anode are oxidations.
The cathode approaches the anode from left to right; while in the creation of an English vocal sound the anode is to the left, the cathode to the right, and the latter approaches the former from right to left.
This performance is of an inverse order as between German and English, in so far as the anode for German vocal sounds is located to the right, the cathode to the left.
The cathode I have discovered belongs to our spiritual life, being a part of a living vocal sound.
The anode is quiescent until the cathode comes along, joins it, and infuses life into it.
What does the motion in which anode and cathodeapproach each other--which is not direct as it at first appears to the observer, but vastly circuitous--signify?
These are imparted to them by the fusion of the cathodeelement of vocal sounds with this, the anode; the spiritual with the material.

The beta rays are identical in type with the cathode rays and are negative electrons.
These rays are slightly deflected by a magnetic field and in an opposite direction from that taken by the cathode rays in their deflection.
These X rays are emitted by various substances under bombardment by the cathode rays (negative electrons) and have great intensity and very minute wave lengths.
When an electrical discharge is passed through a vacuum tube with a cathode having holes in it, luminous streams pass through the holes toward the side away from the anode and the general direction of the stream.
They originate from the anode of the tube owing to the fierce bombardment to which the cathode rays subject it.
Where the cathode rays, which travel in straight lines, first strike any material object, from that same object the X-rays originate.
The positive terminal of an induction coil or Wimshurst machine is connected to the anode and the negative to the cathode of the tube.
The cathode screen came to life suddenly with a picture of the young man sitting at his sending-set, his back turned, watching a screen at one side which showed a glimpse of a huge dark plain approaching.
A shabby radio sending set stood beside it without a case to conceal its parts, two cathode television tubes flickering nakedly on one side and the speaker humming on the other.
Cathode rays had finally proved the key to the riddle.
To the anode he attached one of the negatives, to the cathode a small piece of iron.
Waving away that orange gas, he reached for the cathode and held it up.
The cell box is built of concrete and is provided with a perforated wrought iron cathode box and graphite anode plates which are separated by an unsubmerged asbestos paper diaphragm.
Say it is found to correspond to 14 molecules of hydrochloric acid in the half of the solution on the side of the cathode and 10 molecules in the half on the side of the anode (see Fig.
The U-tube is surrounded by ice water during the passage of the current, and the cathode is placed in the solution on the colorless side.
The fusion is conveniently made in a platinum dish; the dish and a platinum cathode are connected with the lighting circuit and an electric lamp.
In the case of a solution of hydrochloric acid, the negative charge on the cathode would attract the hydrogen ions and repel the chloride ions, and the positive charge of the anode would attract the chloride ions and repel the hydrogen ions.
Then the anode half has lost 5 ions of hydrogen, which must have passed through the diaphragm toward the cathode and taken the place of five of the six hydrogen ions discharged at the cathode.
Since the solutions were of equal concentration to start with, the hydrogen ions have moved ‹five times as fast› toward the cathode as the chloride ions have moved toward the anode.
Research on Electrolysis of Water With a Hydrogen Diffusion Cathode To Be Used in a Rotating Cell.
Resting cells of Hydrogenomonas eutropha consumed hydrogen produced at the cathode of an electrolysis cell built into a specially constructed Warburg flask.
This is an electrolytic rectifier in which the cathode is a rod of aluminum alloy held centrally in a leaden vessel which forms the anode and contains the electrolyte, a concentrated solution of ammonium phosphate.
Only a short portion at the lower end of the cathode is utilized, the rest, which is rather smaller in diameter, being protected from action by an enclosing glass sleeve.
It consists of an exhausted glass vessel containing one anode or positive terminal in each of the two upper arms, two mercury starting anodes and a cathode or negative terminal of mercury at the bottom of the tube.
The cathode is a hollow cylinder of aluminum placed concentrically in a larger cylinder of lead, and the whole immersed in electrolyte of sodium phosphate in an ebonite containing vessel.

It is of the Nodon type employing a cathode of magnesium-aluminum alloy, and probably iron or lead as anode, with an electrolyte of ammonium borate.
I have in the above experiments demonstrated the normal effect of anode in inducing expansion and acceleration of rate of growth; the cathode was shown to induce contraction and retardation of growth.
On application of the cathode the rate was reduced to 0.
If the cathode induced a retardation, the anode might be expected to induce an acceleration of growth.
Before describing the effect of unilateral application of an electrical current in inducing tropic curvature, I shall give an account of the polar effect of anode and cathode on the pulvinated and growing organs.
Application of cathode at the pulvinule was found to exert a contractile reaction, exhibited either by the reduction of normal limit of diastolic expansion, or by an arrest of movement at systole.
Retardation of rate of growth under the action of cathode (Kysoor).
Unilateral application of anode and cathode thus induces appropriate curvatures in pulvinated and in growing organs.
The object of this investigation was to determine whether anode and cathodeexerted similar discriminative and opposite effects on growth.

Lenard, a young Hungarian, pupil of the illustrious Heinrich Hertz, was the first to inflict a serious blow on the hypothesis, by showing that the cathode rays could exist outside the tube in air at ordinary pressure.
Electrons, which constitute the cathode rays, were originally studied in Crookes vacuum tubes, though they are now found to pervade the universe.
These were the immediate pioneers of the discovery of the cathode rays and the other great radio discoveries of recent years.
The cathode, together with the cathode rays charged with negative electricity, emits canal rays charged with positive electricity.
We can, as for the cathode rays, measure the two deviations and thence deduce the velocity and the ratio [epsilon].
But we have the cathode rays, the X-rays, those of uranium and of radium.
It is true that Hertz believed he had demonstrated that the cathode rays do not carry electricity, and that they do not act on the magnetic needle.
Now these cathode rays are deviated by the magnet.
This is why I said above that the experiments on the cathode rays appeared to justify the doubts of Lorentz concerning Newton's principle.
Afterwards, and quite recently, the action of the cathode rays on the magnetic needle has been put in evidence.
If we had only thecathode rays properly so called, it could not be dreamed of; but happily we have the rays of radium which, as we have seen, are notably swifter.
What had only been proved for cathode corpuscles was extended to all bodies.
Thus all these phenomena regarded as currents of convection, sparks, electrolytic currents, cathode rays, act in the same manner on the galvanometer and in conformity with Rowland's law.
