 General questions anJ announcements 



I. The Hubrecht Laboratory. 



The Laboratory has undergone an internal remodehng. Six new laboratory 

 rooms have been added, and consequently the number of working-places has 

 increased from about 10 to about 20. Moreover a new and modern aquarium 

 room is now in use, and two constant-temperature rooms have been constructed, 

 one for 20°— 25° C. and the other one for 35°— 40° C. The latter room has 

 been designed for the work on avian eggs which is planned for the future. 



IL The Central E m b r y o 1 o g i c a 1 Library. (C.E.L.) 



A. Organisation, extension etc. 



The card-index of the collection of reprints is three-fold, viz. according to 

 1. years of appearance, 2. authors and 3. subjects. The classification-system 

 used for the subject-index is the same as that used in the G.E.LS. 



We want to tank those wo this year again sent us reprints. We hope that 

 all embryologists will realize the importance of sen- 

 ding their reprints (in two- fold) to the Central Embryo- 

 logical Library, where they will particularly be of great use both to 

 the guest-workers of the Hubrecht Laboratory and to the embryologists 

 working in those parts of the world where the supply of Hterature is restricted. 



Our plans for an annual survey of embryological literature have been 

 replaced by plans for an Abstracting Preview Service. For further data see 

 chapter g (page 156). 



May we remind you of our request to place in the C.E.L. those private 

 collections of books and reprints which are not in use any more and which may 

 otherwise get lost? 



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



1 . Every embryologist can ask for information about literature 

 of certain authors, for surveys of hterature on certain subjects (accord- 

 ing to the classification-system of the G.E.LS.), for surveys of newly 

 published literature, etc. 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 Holland. 



Conditions. 



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

 Holland 1 month), time for shipment not included. 



b. The receipt, added to the consignment, must be returned b y 

 return of post, after having been controlled and signed. 



c. In case of high forwarding-charges they 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 disposal of every embryologist who is carrying 

 out scientific work at the Hubrecht Laboratory. 



in. The Central Embryological Collection of slides 

 and material.
