THE Eleventh International Congress of Zoologists, which met in Padua on Sept. 3–11, under the presidency of Prof. Paolo Enriques, attracted more than six hundred members, representing thirty countries. The British delegates were Dr. F. A. Bather and Dr. G. C. Robson (representing H.M. Government), Dr. K. Jordan, Dr. H. W. Parker, Lieut.—Col. J. Stephenson (Indian Government), and Prof. A. Willey. In the Aula Magna of the University, surrounded by memorials of Galileo, Morgagni, Vesalius, Falloppio, Casseri, and Vallisnieri (nor should we here forget Linacre and Harvey), the Congress was formally opened by H. E. Alfredo Rocco, Minister of Grace, Justice, and Culture, as representative of the Government and as president of the Italian Committee for International Intellectual Co-operation. He expressed the deep practical interest felt by the Italian Government in zoological studies, alluded to the contributions of Italians from Leonardo da Vinci to the present day, and mentioned the Zoological Station of Naples and the Biological Institute of Messina as schools open to the students of the whole world.
