An invitation circular has been widely circulated to all members of Eugenic and Heredity Societies in Europe and America, and to many other persons likely to be interested in the approaching Congress. Through that circular the objects and general plan of the Congress have been made widely known. Copies may still be had on application to the Secretary. The following arrangements have now been definitely made. =Place of Meeting.= The Meetings of the Congress will be held in the Great Hall of the University of London, Imperial Institute Road, South Kensington, London, S.W., which is easily reached from South Kensington Station on the Underground Railway, and by omnibus from all parts of London. (In wet weather those travelling by rail can avail themselves of the subway). =Headquarters of the Congress.= Until Tuesday, July 23rd, the headquarters and offices of the Congress will remain at 6, York Buildings, Adelphi, W.C. (close to Charing Cross Station), where all information will be supplied and tickets issued. Office hours 10-30 a.m. to 5 p.m. On and after Wednesday, July 24th, the headquarters will be transferred to the University of London, South Kensington. If arrangements for hotels or for lodgings have not been made previously, members arriving on and after July 24th are recommended to leave their luggage in the "Cloak Room" at the railway station and come to the office of the Congress, at London University, South Kensington, for information. =Correspondence.= From July 24th to 30th, Members and Associates of the Congress may have their letters addressed to them at the First International Eugenics Congress, c/o The University of London, South Kensington, S.W., where special postal facilities will be provided. All invitations to Receptions, etc., will be distributed in this way. =Languages.= It has been decided that in the Meetings and Discussions the English, French, German, and Italian languages shall be on an equal footing. At the same time it is right to point out that in all Congresses the number of Members speaking and understanding only the language of the country in which they are held has been far in excess of those conversant with several languages; therefore those who speak in English on the present occasion will be most widely understood. The abstract of every paper which is received in time by the Secretary will be translated into English, French, and German. Pamphlets containing the abstracts in these languages will be available on July 24th at the University Buildings. Members wishing for advance copies should notify the fact to the Secretaries, and state clearly in what language they are required, and to what address they should be sent. =Stewards.= A number of Stewards acting as interpreters will be in attendance; the languages spoken being indicated by rosettes of the following colours:--Red, French; Blue, German; Green, Italian.
