 General questions and announcements 



I The Hubrccht Laboratory 



The year 1954 has been an important year in the development of the 

 Hubrecht Laboratory. The first international team-work in the field of embryo- 

 logy was held from February 1st till July 31st and has been very successful. 

 The following scientists (in alphabetical order), participated in the team: 



I ) Miss R. de Fremery (M.Sc). (now Mrs Verhoef-de Fremery). 



Utrecht. Holland 



2) Mr T. W. Glenister (M.B.. B.S.). London. England 



3) Mr K. Hara (M.Sc). Nagoya. Japan 



4) Miss D. Harari (M. Sc), Jerusalem. Israel 



5) Mr O. Hassa (Vet.D.). Ankara. Turkey 



6) Mr R. Hori (M.Sc). Toyama. Japan 



7) Miss A. G. Johnen (Ph.D.). Cologne, Germany 



8) Mr D. J. McCallion (Ph.D.). Wolfville. Canada 



9) Miss V. M. McMurray (Ph.D.), Iowa, U.S.A. 

 10) Mr M. Sala S.J. (Phil.D.), Padova, Italy 



This team represented 9 different countries of three continents. The general 

 topic of the team-work was: ,, Origin and establishment of organisation patterns 

 in embryonic fields during early development in Amphibians and Birds, in 

 particular in the nervous system and its substrate." 



After a technical and theoretical introduction into the general topic, seperate 

 investigations have been carried out by the various participants under the per- 

 .sonal direction of Dr P. D. Nieuwkoop. A joint preliminary publication has 

 been written on the results already obtained, which will be published in due 

 course. 



As a direct effect of this team-work experimental embryological work is 

 being newly established at the Veterinary School in Ankara (Turkey), the 

 University of Jerusalem (Israel) and the Charing Cross Hospital in London 

 (England), while new stimuli have been given to the work of several other 

 participants already engaged in experimental biology. 



The next team-work will be held at the Hubrecht Laboratory in the year 

 1956. We have the intention to prolong the duration of the team-work with 

 one month in order to secure a better acquaintance of the participants with the 

 language chosen as medium. The team-work will therefore be held from 

 January 15th till August 15th. The general topic, leadership and further details 

 will be announced by circular, to be distributed in the beginning of next year, 

 so that applications can be sent in before September 1st of 1955. 



II The Central Embryological Library (C.E.L.) 



A Bibliographical information; Normal Tables 



For bibliographical information supplied to embryologists on request (cf. 

 II B) we make use in the first place of the reprint-collection, with its card- 

 index composed according to the classification-system used in the G.E.I.S.. 

 and in the second place of the periodicals present in the C.E.L. Among these 

 the abstracting-journals form an important source for informations. Those 

 present in the C.E.L. are: ..Berichte iiber die Wissenschaftliche Biologie". 

 ..Biological Abstracts" Sections A and B. and ..Excerpta Medica" Section I.
