Take, for instance, that of the eclipse of 1900. It dhoom 1 720p be noticed in this photograph that the corona appears to consist of two portions one comprising the polar rays just spoken of, and the other consisting of the broader, longer, and less-defined masses of light extending out dhoom 1 720p the equatorial and middle-latitude zones. Yet even in this more diffuse part dhoom 1 720p the phenomenon one can detect the presence of submerged curves bearing more or less resemblance to those about the poles. Just what part electricity or electro-magnetism plays in the mechanism of the solar radiation it is impossible to say, but on the assumption that it is a very important part is based the hypothesis that there exists a direct solar influence not only upon the magnetism, but upon the weather of the earth. This hypothesis has been under discussion for half a century, and still we do not know dhoom 1 720p how much truth it represents. There have been occasions when the influence has manifested itself in the most startling ways, a great solar outburst being followed by a mysterious gripping of the cable and telegraph systems of the world, as if an invisible and irresistible hand had seized them.
