256 International Organization 



1950) the following presidents were appointed, for the Academy, Dr. J. A. Voll- 

 GRAFF of Leiden, for the Union, George Sarton of Cambridge, Mass. 



The Perpetual Secretary is Prof. Pierre Sergescu. The offices of the Academy 

 and of the Union are located 12 Colbert, Paris 2 (near the Bibhotheque Nationale). 



There may be other international organizations devoted to the history of sci- 

 ence in general, or the history of particular sciences. The line between a national 

 organization and an international one is not always easy to draw as we exemplified in 

 the case of the History of Science Society. In the first place, national societies may 

 recruit members in other nations, and if their publications are made in one of the 

 international languages (EFGILS) and are sufficiently useful, the number of for- 

 eign members may exceed that of the domestic ones. On the other hand, every 

 international organization is of necessity established and domiciliated in a definite 

 country and cannot help being more or less nationalized, because its contacts with 

 that country are more frequent and more intense than with any other.^"'^ 



1921: Societe Internationale d'Histoire de la Medecine. — Founded in Paris on 

 8 October 1921 by Joseph Tricot-Royer of Antwerp, and others, at the meeting 

 of the permanent committee of the International Congress of the history of medicine. 

 Its official organ was first the Bulletin de la Societe frangaise d'histoire de la medecine 

 (see 1921, 15: 312-13). When Aesculape resumed its publication in 1923 with 

 vol. 13 it became the organ of the society and remained so until 1940 when it 

 ceased to appear. The Societe also published Archives (?), no. 4 of which is said 

 to have appeared in 1938. Not seen. 



The permanent committee of the Societe meets at the Faculty of Medicine of 

 Paris. President, Prof. Laignel-Lavastine, general secretary, Jules Guiart (Ar- 

 chives intern, d'hist. des sciences 28, 733-35; 29, 154-56; etc.). 



1948: International Plant Science Relations and Phytohistorical Commission of 

 the International Union of Biological Sciences. — Founded by, and under the 

 chairmanship of, Frans Verdoorn, Chronica Botanica House, Waltham, Mass. 

 Chiefly concerned with the preparation of ( i ) the World List of Plant Science In- 

 stitutions and Societies (ed. 21, 1952), (2) Biologia, an international year-book 

 (vol. 3, in press, includes the Verdoorns' eleventh report on International Coopera- 

 tion in the Pure and Applied Plant and Animal Sciences and emphasizes work on 

 the borderland between the natural sciences and the humanities), (3) the Index 

 BoTANicoRUM, a biographical dictionary of plant scientists of all times. The Com- 

 mission also maintains a card index of current research projects concerned with 

 the history of any branch of the pure and applied plant sciences.

Further information on the Index Botanicorum will be found in Chronica 

 Botanica 8, 425-448, 1944. A four-page progress report, with a list of collaborators, 

 was issued in 1948. The commission is at present preparing a three-volume Concise 

 Dictionary of Botanical Biography (a prodromus to the Index Botanicorum.). 



los This would be the case even if the small territory occupied by the international organization 

 was internationalized. The Popes of Avignon were influenced by the French environment even 

 as the Popes of Rome by an Italian one.
