A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which it may be made to move. ↗

Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase - that is, as the wavelength decreases. ↗

By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms. ↗

By recognizing that the chemical atom is composed of single separable electric quanta, humanity has taken a great step forward in the investigation of the natural world. ↗

It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we do our solar system. ↗

Many scientists will have to contribute to the solution of the great problem; they will have to follow up and measure all those phenomena in which the atomic structure is directly expressed. ↗

The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself made up of several units into a selfcontained whole. ↗

The emitters of the spectral series are without exception single atoms, not compounds of atoms. ↗

The movement of the emitters of the spectral lines may be deduced on the basis of the Doppler principle. ↗

The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks. ↗
