THE Muséum d'Histoire Naturelle in Paris has set up a Centre for Studies and Documentation in Palæontology to provide, in the form of microfilm, photocopy or letter, information and bibliographical or systematic references on the following subjects : (1) General information about the different sciences of the earth ; for example, details about the location of extensive collections of geological or stratigraphical terms, etc. (2) Bibliographical information on the different sciences (mineralogy, petrography, tectonics, geophysics, applied geology, regional geology, stratigraphy, general palæontology, biological questions of interest to the palaeontologist). (3) References and figured slips dealing with animal and plant systematics in general (bibliographies, lists of types, lists of genera and higher groups, systematic groupings). In addition to patæontological study, collections of the Centre can be consulted on the spot. Information on the above subjects is obtained by regular analysis of some 2,500 journals. Special studies can also be made, on request, for the period prior to 1940 or on any particular subject. The Centre also undertakes summaries of various articles, translations of articles published in Russian or Polish, and the preparation of figures of type-specimens in old collections. These documents are listed as they are completed in a small three-monthly bulletin. The use of the Centre is open to all, and in addition members (annual subscription of 300 fr.) receive the bulletin free of charge and can obtain reproductions at special rates. All inquiries should be addressed to : Prof. Roger, Centre d'Études et de Documentation Paléontologiques, 3 Place Valhubert, Paris 5. Payments should be made to Syndicat de Documentation Géologique et Paléontol-ogique, 61 Rue de Buffon, Paris 5.
