As an example of how the plan will work in the case of any one section, the Committee take the case of a neurologist desiring to profit by those discussions which relate to his branch of medicine. This falls under C of the four main divisions as related to the physical sciences. His interest on the first day will therefore be centred in Division C, where he may hear the general discussion of the physical sciences and the relations to the other sciences. On the second day he will hear four papers in Group 18 on the Subjects embraced in the general science of anthropology; one on its fundamental conceptions; one on its methods and two on the relation of anthropology to the sciences most closely connected with it. During the remaining four days he will meet with the representatives of medicine and its related subjects, who will divide into sections, and listen to four papers in each section. One paper will consider the progress of that section in the last one hundred years, one paper will be devoted to the problems of to-day, leaving room for such contributions and discussions as may seem appropriate during the remainder of the day. COÖPERATION OF LEARNED SOCIETIES INVOKED In presenting this general plan, your Committee wishes to point out the difficulty of deciding in advance what subjects should be included in every section. Therefore, the Committee deems it of the utmost importance to secure the advice and assistance of learned societies in this country in perfecting the details of the proposed plan, especially the selection of speakers and the programme of work in each section. It will facilitate the latter purpose if such societies be invited and encouraged to hold meetings at St. Louis during the week immediately preceding, or, preferably, the week following the General Congress. The selection of speakers should be made as soon as possible, and, in any case, before the end of the present academic year, in order that formal invitations may be issued and final arrangements made with the speakers a year in advance of the Congress. CONCLUDING SUGGESTIONS With the view of securing the coöperation of the governments and leading scholars of the principal countries of Western and Central Europe in the proposed Congress, it seems advisable to send two commissioners to these countries for this purpose. It seems unnecessary to extend the operations of this commission outside the European continent or to other than the leading countries. In other cases arrangements can be made by correspondence. It is the opinion of the Committee that an American of world-wide reputation as a scholar should be selected to preside over the Congress.
