Abstract
In previous discussions of the above named work (ibid., vol 14, pp 663, 1926) the observations on Madras (Fort) Radio were found to be too brief for a good comparison with terrestrial and cosmic elements. The present discussor's observations taken in the Far East on Rugby's transmissions cover rather longer periods than those given by K. Sreenivasan (ibid., vol 15, pp 155, 1927) and may perhaps be useful to other investigators. A curve (see Fig. 1) is given for moving weekly averages of observations of Rugby's midnight (GMT) transmission on 18,750 metres. It is noted that the curve for October and November shows intensity changes similar to K. Sreenivasan's observations of Madras. The various curves given in a second figure were taken during three voyages from Liverpool to Japan and back (via Suez) and cover a period of fifteen months, the time and wavelength of the transmission being the same as in Fig. 1. Many of the sudden and rapid changes in the curves were obviously due to screening by nearby land.
