To the watchful care of Professor Hilgard for the interest of the public service and his intimate relations with leading scientific men at home and abroad is mainly due the present standing of the office. As a member of the International Committee on Weights and Measures, to which body he has been accredited by the President of the United States, Mr. Hilgard, as vice-president of the commission, will take passage for Europe before the close of the present month to attend a meeting of the body at Paris.
