At Yale University I had the pleasure of representing the University of Paris at the inauguration of President Angell, fourteenth president of the University. I was also pleased to attend at Philadelphia a meeting of the American Philosophical Society and a meeting of the College of Physicians, and at Chicago a meeting of the American Chemical Society at which I delivered a lecture on the Discovery of Radium. The medals of John Scott, Benjamin Franklin, and Willard Gibbs have been presented to me by these societies. Several meetings organized in my honor by the American women's organizations have particularly interested the American public. I have already mentioned the meeting of the University Women at Carnegie Hall of New York; a similar meeting was held at Chicago, where I was also received by the Association of Polish Women. I was also greeted by women's organizations in the Carnegie Institute of Pittsburgh, and by a delegation of Canadian university women at Buffalo. In all these meetings it was impossible not to recognize the sincerity of the emotion in the women who gave me their best wishes, at the same time expressing their confidence in the future of feminine intelligence and activity. I did not feel any opposition between these feministic aspirations and the masculine opinion. As far as I could notice, the men in America approve of these aspirations and encourage them. This is a very favorable condition for the social activity of the American women which reveals itself in a strong interest in work for education, for hygiene, and for the improvement of conditions of labor. But any other unselfish purpose may rely on their support, as is proved by the success of Mrs. Meloney's plan, and by the sympathy this plan encountered in women of all social conditions. I could not, to my deep regret, give time enough to the visit to laboratories and scientific institutes. These too brief visits were of great interest to me. I found everywhere the greatest care for developing scientific activity and for improving the facilities. New laboratories are in building, and in older laboratories very modern equipment may be found. The available room never gives that impression of insufficiency from which we suffer too often in France. The means are provided by private initiative expressed in gifts and foundations of various kinds. There exists also a National Council of Research established by private funds for stimulating and improving scientific work, and for assuring its connection with industry. I have visited with special interest the Bureau of Standards, a very important national institution at Washington for scientific measurements and for study connected with them. The tubes of radium presented to me were at the Bureau, whose officials had kindly offered to make the measurements, and to take care of the packing and delivery to the ship.
