Communications from the Hubrecht Laboratory 



I The team work project 



In connection with the development of the building project (see below) the 

 next international team work will almost certainly not be held before 1964. 

 In the meantime, however, there will still be available a limited number of 

 places for individual foreign guest workers in the old building. 



II The building project 



Various factors have retarded this project. It is now hoped that the building 

 activities can be started early in 1962. The new building could then be ready 

 by the end of 1963. 



III The scientific staff 



In the beginning of 1961 the biochemist Dr. D. O. E. Gebhardt joined the 

 staff. He is carrying out preparatory work for the future histo- and cyto- 

 chemical unit. 



In the course of 1962 Dr. Kirstie Lawson (Cambridge) hopes to join the 

 staff, and to start the organisation of the tissue- and organ-culture research 

 unit. 



It is hoped that in the course of 1962 a biophysicist can be appointed, who 

 will be asked to make a start with the biophysical approach to developmental 

 problems, in connection with the establishment of a biophysical research unit. 



The three units mentioned will then already be well prepared before moving 

 into the new building. 



Dr. J. Faber is hoping to go abroad for specialization in the field of develop- 

 mental genetics in 1962/63. 



IV Guest workers 



Mr. Koki Hara (Nagoya), who has stayed at the Laboratory since 1958, 

 obtained his Ph.D. from the University of Utrecht in November 1961, on a 

 thesis entitled "Regional neural differentiation induced by prechordal and pre- 

 sumptive chordal mesoderm in the chick embryo". 



Two members of the fourth international team stayed on afterwards at the 

 Laboratory and concluded their studies in 1961: Dr. M. I. Michael (Alexan- 

 dria) carried out an experimental analysis of the development of the sensory 

 placodes, the cephalic ganglia and other derivatives of the head neural crest 

 in urodeles, while Mr. M. Corner (New York) studied the properties of 

 isolated neural plate regions during the neurula stages in amphibians by means 

 of the explant technique. 



Miss F. E. Ince (London) stayed at the Laboratory for three months to 

 study experimental techniques. 



Two new guest workers arrived in 1961: Dr. M. S. Falakali (Izmir, Turkey) 

 will carry out a quantitative analysis of the distribution of the neural crest 

 along the margin of the neural plate in amphibians, while Mr. J. D. Babb 

 (Gambier, Ohio) is planning an investigation concerning the propagation of 

 inductive influences through competent ectoderm in urodeles.
