THE EINSTEIN THEORY.

PREDICTIONS FULFILLED.

OBSERVATIONS AT WALLAL.

"PHENOMENAL AGREEMENT"

By Telesrr»t>li —Press Association Copyright. A. and N.Z. NEW YORK, April 12.

A message from Mount Hamilton Observatory, California, states that calculations made from the photographs taken by the Lick Observatory expedition during the total eclipse at Wallal, Western Australia, bear out the Einstein theory. Two photographs of stars surrounding the sun during the eclipse were taken, and these were compared with the photographs of the same stars taken at Tahiti three months earlier.

The director, Mr. . Campbell, and Dr. Trumpler, of the lack Observatory staff, announced that the agreement between Einstein's ; prediction as to the displacement of the stars' rays outward with reference to the centre of the sun, and the extremely exact measurements made by these two scientists of the photographic plates, is absolutely phenomenal.

Einstein predicted that the displacement of the stars' rays while passing through the sun's gravitational field would be one and three-quarter seconds of arc. The scientists, subjecting as many as 84 stars appearing on the plates to most rigorous mathematical treatment, found the displacement to average one and seventy-four hundredths of a second of arc.

Dr. Campbell stated that the agreement between the observed value with the predicted value is so satisfactory that the Lick Observatory does not plan to repeat the Einstein tests at the total solar eclipse which will be visible in California and Mexico on September 10.
