Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1878 edition. Excerpt: ...this and the glow at the negative. As the tension fell, the negative glow became globular, then elongated, and lastly reached the central luminosity; suddenly the central luminosity disappeared, and left a dark interval in its place. This last phase is shown in fig. 60. Tube 66, length between the terminals 28 inches, diameter 2 inches. Hydrogen. 198.--The arrangement the same as for 197. With the full potential a splendid phenomenon of 18 steady strata was produced; as the potential fell more strata gradually crowded in from the positive until they reached 43 in number, after which they became confused. With 6,150,000 ohms resistance in circuit there was a rapid flow in which alternating greenish and reddish cross markings were seen; the rotating mirror resolved these into strata alternately pink and greenish. The resistance of the tube was found to be Gassiot (Proc. Roy. Soc, vol. xii., 1862-3, p. 336) describes a similar phase: "Depressing the wire very gradually (lessening the resistance) the positive became sharply defined, the negative retaining much of its irregular termination, but each separated by a dark interval of about one inch in length." Mr. Spotttswoode informs us that at an early stage of his experiments he noticed the formation of large cylindrical blocks of light or luminosities, terminated by flat ends, and separated by dark intervals often as long as themselves. These were most frequently found in tubes from 2 to 3 inches in diameter, containing coal-gas residua, at G"5 to 0-75 m.m. pressure; they were from 2 to 3 or even 4 inches in length, and sometimes shot out from the positive terminal, then travelled along the tube, and finally disappeared in the dark space towards the negative terminal.
