For they were closely paralleled by some earlier experiments of Wiedemann, in which the gaseous spectra of vacuum tubes were at once effaced on the introduction of metallic vapours. It seemed as if the metal had no sooner been rendered volatile by heat, than it usurped the entire office of carrying the discharge, the resulting light being thus exclusively of its production.
Wiedemann says, it is an unfortunate fact that all the texts which we possess are, in respect of the period of the origin of the Egyptian religion, comparatively late, and therefore in them we find these three elements mixed together, along with a number of foreign matters, in such a way as to make it impossible to discover which of them is the oldest.
Before returning to Florence, they spent a week in the city to see the churches and the pictures by Sodoma. Even little Wiedemann screamed for church-interiors and developed remarkable imitative pietisms of a theatrical kind. "It was as well," said Browning, "to have the eyeteeth and the Puseyistical crisis over together."
He was baptised, with the simple Lutheran rites, Robert Wiedemann Barrett the "Wiedemann" in remembrance of the maiden name of Browning's mother. From the first, Browning and his wife, to adopt a phrase from one of her letters, caught up their parental pleasures with a sort of passion.
So popular was it in England in 1824 that no less than nine theatres were presenting various versions of it at the same time. The original cast was as follows: AGATHA Frau CAROLINE SEIDLER. ANNCHEN Frl. JOHANNA EUNIKE. MAX Herr CARL STÜMER. CASPAR Herr HEINRICH BLUME. OTTAKAR Herr RUBINSTEIN. KUNO Herr WANER. HERMIT Herr GERN. KILIAN Herr WIEDEMANN.
Why principally the negative flame returns may be explained in two ways either the point of the flame loses much by radiation, or the base of the flame is a bad conductor. The former explanation would agree with the experiments made by Wiedemann and Ruhlmann, the latter with Erdman's theory of unipolar conductivity of flames.
During this winter in Paris, little Wiedemann, as his parents tried to call him his full name was Robert Wiedemann Barrett had developed a decided turn for blank verse. He would extemporize short poems, singing them to his mother, who wrote them down as he sang.
This, in brief, is the celebrated hypothesis of "radiant matter," which has been supported in the United Kingdom by champions such as Lord Kelvin, Sir Gabriel Stokes, and Professor Fitzgerald, but questioned abroad by Goldstem, Jaumann, Wiedemann, Ebert, and others.
For a long time it was noticed that the phenomena in a Geissler tube changed their aspect considerably, when the gas pressure became very weak, without, however, a complete vacuum being formed. These are the cathode rays, so named in 1883 by E. Wiedemann, and their name, which was unknown to a great number of physicists till barely twelve years ago, has become popular at the present day.
The suggestion of Italian characteristics in the Poet's face may serve, however, to introduce a curious fact, which can have no bearing on the main lines of his descent, but holds collateral possibilities concerning it. His mother's name Wiedemann or Wiedeman appears in a merely contracted form as that of one of the oldest families naturalized in Venice.
