 HUBRECHT LABORATORY 



I The scientific staff 



In June 1969 an eleventh member joined the staff: Mr. S. W. de Laat, M.Sc. 

 He will be in charge of the new research unit of developmental biophysics. With 

 his arrival the scientific staff is complete, and the space available for research 

 units in the Laboratory is fully occupied. 



Mr. J. A. Leussink, M.Sc, who served the Laboratory as its Administrator 

 through a long series of years, left the Laboratory on October 1st. The vacancy 

 will be filled in 1 970. 



II Annual Scientific Report 



It has been decided henceforth to publish an annual scientific report in 

 English. The report will be printed by the Royal Netherlands Academy of 

 Sciences and Letters, and will be distributed on a large scale in the form of a 

 reprint. The report for 1968 is fortcoming. 



III The international team project 



The seventh international team in embryology will most probably meet in the 

 first half of 1972, The subject has not yet been fixed. A circular pertaining to 

 the team will be distributed at least 1 h^ year in advance. 



IV Foreign guests 



Most of the guests who worked at the Laboratory in 1969 were already there

Dr. W. P. Luckett (Madison, Wis.) stayed at the Laboratory from May till 

 July to work in the Central Embryological Collection (early mammalian placen- 

 tation). Dr. M. Klima (Brno, Czechoslov.) worked in the Collection for two 

 weeks during November (development of the sternum in monotremes and 

 marsupials). Dr. K.-I. Sirakami (Yamanashi Univ., Kofu) visited the Labora- 

 tory for three weeks during August and September, mainly to use the Central 

 Embryological Library. 



V Facilities for international use 



These facilities comprise the Central Embryological Collection, and the 

 Central Embryological Library, with its extensive reprint collection and its 

 bibliographical and copying services. Details pertinent to these facilities may 

 be found in the information booklet distributed on a large scale in 1966. This
