 Communications from tlie Hubrecht Laboratory 



I The building project 



The construction of the new building was started at the beginning of this 

 year and has made very good progress. We expect that the building may be 

 completed by the end of 1963. 



II The team work project 



Since preparations for the organisation of an international team work 

 require at least one full year and since we like to be sure that the organisation 

 of the new building functions properly before receiving a larger number of 

 foreign guests, the next international team work will be held in the first half 

 of 1965. The announcement may be expected in the second half of 1963, so 

 that all applications may be sent in by the end of 1963. 



In the meantime there are still available a limited number of places for 

 individual foreign guest workers in the old building. 



III The scientific staff 



The scientific staff of the Hubrecht Laboratory comprises at present the 

 following members: 



Prof. Dr. P. D. Nieuwkoop, general and scientific director. 



Dr. J. Faber, who will be in charge of the scientific unit for developmental 

 genetics, is at present working in the institute of Prof. Dr. E. Hadorn in 

 Zurich for his further specialisation in that field. 



Miss E. C. Boterenbrood, who received her Ph. D. degree in July of this 

 year, will be in charge of the unit of descriptive and experimental morphology. 



Dr. D. O. E. Gebhardt (biochemist) will guide the scientific work in the 

 unit for developmental physiology. 



(Miss) Dr. K. Lawson joined our staff in September of this year and will 

 be in charge of the unit for tissue and organ culture. 



Dr. K. Hara has recently joined our staff and will guide the unit of photo- 

 and cinematography. 



Mr. J. A. Leussink, who is working for his thesis, directs at present the 

 reorganisation of the Central Embryological Library. 



It is hoped that soon a biophysicist will join our staff for the unit of deve- 

 lopmental biophysics as well as a histologist or biochemist for the unit of 

 histology and histo- and cyto-chemistry. 



In the near future the directorship of the institute will be split into a scien- 

 tific and an administrative position, so that the scientific director will have 

 more time available for the coordination and integration of the scientific work 

 in the various units. 



IV Guest workers 



Dr. M. S. Falakali (Izmir, Turkey) stayed from September 1961 till the 

 end of April of this year and studied various experimental embryological 

 techniques.
