...29th of this year there occurred a solar eclipse in Europe and pictures were taken of certain stars then seen to be near the sun. It was found by measurement that these stars were represented as being farther apart than they normally should be. That is, the rays of light had been bent while passing the sun. Einstein had predicted that this bend would be one and seven tenths seconds and this is precisely what was found to be true...
...theory Einstein also stated that in a spectrum the solar lines would be shifted toward the red, but as no such shift has yet been found many scientists are inclined to doubt the truth of the whole theory. The inaccuracy of all instruments, however, may well be the cause of this failure and the first two proofs considered sufficient evidence of the correctness of the theory...
...unexpected announcement of Professor Edward C. Pickering's death," said Professor Bailey, "brought instant response. Campbell, Director of the Lick Observatory, telegraphed, 'A great, unselfish man has gone. Our flag is at half-mast,' Hale, Director of the Solar Observatory, Mt. Wilson, 'Am greatly shocked and grieved, and hasten to send sincere sympathy.' Klotz, Director of the Dominion Observatory, Ottawa.

Plaskett, Director of the new Canadian Observatory, at Victoria, 'The news came to Mrs. Plaskett and me as a great shock and deep personal loss...
...establishment of the Henry Draper Memorial Fund has made possible the study of the spectrum of the stars. The Observatory has been eminently successful in this work and a classification was drawn up which was accepted last summer by the International Solar Union at Bonne to be the authentic system. In this work, a large number of new stars, variables and other peculiar objects have been discovered. A catalogue classification of 200,000 stars is now being prepared at the Observatory by Miss Cannon at the rate of 5,000 a month. This will fill eight volumes of the annals...
