Communications Ironi the Hubreciil Laboratory 



I The Laboratory 



In the year 1958 (March 15th — September 15th) the third international 

 team work on embryology will be held at the Hubrecht Laboratory under the 

 joint direction of Prof. Dr Chr. P. Raven of the University of Utrecht, and 

 of Dr P. D. Nieuwkoop, Director of the Laboratory. 



The topic for the third team will be: "A morphological and physiological 

 analysis of regulative and non-regulative processes in the development of 

 "mosaic" eggs of several terrestrial and freshwater invertebrates" . 



As far as is known at the present moment, the following scientists will parti- 

 cipate in this team (alphnhctical order): 

 Miss A. Andrew, M.Sc. Johannesburg, South Africa 

 Dr J. C. George. Baroda. India 

 Dr C. Jura, Krakow, Poland 

 Dr J. B. Morrill, Tallahassee. Flor.. U.S.A. 

 Dr I. Nakamura, Tokyo, Japan 

 Mr E. Suminsky, M.V.Sc, Warszawa, Poland 

 Dr G. Szekely, Pecs, Hungary 

 Dr S. Seo, Fukuoka, Japan 



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

 A Extension of reprint collection 



Recently a programme of collaboration has been established with the Ex- 

 cerpta Medica Foundation. Amsterdam, which will enable us to have regular 

 access to the most recent literature received by this Foundation. This means, 

 firstly, that the reprint collection will be more complete, and secondly, that in 

 many cases it will be possible to acquire reprints at a much earlier date than 

 has been the case until now. 



B Services rendered by the C.E.L.; conditions for borrowing 



1 . Every erabryologist can ask for information about literature of 

 certain authors, for surveys of literature on certain subjects (according 

 to the classification-system of the G.E.I.S.), for surveys of newly 

 published literature, etc. 



2. Every embryologist can borrow reprints which are not available 

 in his own country. Books and Normal tables are usually not lent out, 

 volumes of periodicals are only lent out to investigators in the Nether- 

 lands. 



Conditions: 



a. Reprints may be borrowed for 3 months at the utmost (for the 

 Netherlands 1 month), time for shipment not included. 



b. The receipt added to the consignment must be returned by return 

 of post, after having been controlled and signed. 



c. In case of high forwarding charges these have to be partly carried 

 by the applicant. 



3. Every embryologist can personally consult the C.E.L. at all 

 times. 



4. The C.E.L. will be at the disposal of every embryologist working at the 

 Hubrecht Laboratory.
