the brightness of the Sun’s disk at the central parts compared with that near its border, the observations of the Zodiacal Light & particularly those relating to its visibility East and West at the same season of the year, the force of the Sun’s radiation, the measure of the heat of the Moon’s radiation, the varying appearance of the lines of the spectrum with the angle of elevation, and the intensity of the Earth’s magnetism at different altitudes.
