In the evening dined with Merills and then Stales lecture on Observation of the Sun from Mt Wilson near Los Angeles a Pasadena California. The appearance of the Observatory is something marvelous. From the many photos of the sun shown one gets the idea of regular sphere orbits any very just protuberances. The sun spots under certain spectroscopic observations are seen to be like vortex-like holes in a mass of celestial gas out of which an shot or whirled by hydrogen gas. The latter can as far as made out also seen on the edge of the sun. An analysis of these hydrogen clouds in their movements over the sun disc's con- nects the with the sun spots. In other words parts of the sun spots move regularly while other parts move irregularly those the hydrogen emanations. All of this work is done by reflecting mirrors of large size. He showed a photo of Andromeda by the same apparatus. A far finer photo than the one of Lick Observatory. In talking on the matter with AT&T at the Grand Hotel Reception he said the Sun was to him a gaseous man with an external temperature of
