NEXT YEAR'S ECLIPSE.

TEST OF EINSTEIN THEOBY. One of the tests *of the Einstein theory is the denccti*i of light coming from stars nearly in line with the sun, by the sun's gravitational field. This can only be observed during a total eclipse, and it will be remembered that the last occasion when observations were made the theory appeared to have received a brilliant vindication in that respect. The next opportunity will be on September 21, 1922, when the sun will be in eclipse as seon from certaiin parts of the Southern . HemisphereTho following extract from a report of the Astronomer-Royal, dated June 4, refers to the steps taken to make observations next year:—

"In conjunction with the Joint Permanent Eclipse Committee it has IJeen arranged that Mr.- Jones and Mr. Melotte shall make observations at Christmas Island of the reflection of light by the sun's" gravitational field. The Admiralty has given- permission for the astrographic telescope to be taken, and it will be fitted on a new stand, designed , for the latitude of Christmas Island. Permission has been by the Admiralty for the observers to stay in Christmas Island for a "period of six months in order to do preparatory work. " The directors of the Christmas Island Phosphate Company have given the observers all available information, and have kindly promised to give the expedition all the assistance in their power. The observers will leave England early in the year 1922."
