The\nwartime suspension of IAU meetings\nproduced a gap of IO years since the pre-\nvious meeting, which was at Stockholm,\nSweden, in August, 1938.\nThe American section of the IAU\nhas decided to confer delegate status\nupon all American professional astron-\nomers who may wish to attend the\nZürich sessions. It is desirable that as\nmany as possible of the American chair-\nmen of commissions and subcommissions\nattend the meeting. All astronomers\nwho intend to go to Zürich should in-\nform Dr. Otto Struve, Yerkes Observa-\ntory, Williams Bay, Wis., so that a\ncomplete list of American delegates may\nbe submitted to the general secretary of\nthe IAU as soon as possible. Dr. Struve\nwill be glad to furnish information con-\ncerning steamship and plane transporta-\ntion and accommodations in Europe."
