It may be of interest to mention that the C.E.L. possesses the greater portion 

 of the Normal Tables included in the list added to the ..Concise Catalogue of 

 the Central Embryological Collection of the Hubrecht Laboratory" (1953). The 

 Tables are usually availabale for borrowing.

III The Central Embryological Collection of slides 

 and material 



A The Collection 



The collection has been extended with the important experimental material 

 of the late Prof. E. Rotmann (Cologne, Germany). 



A Concise Catalogue of the Central Embryological Collection of the 

 Hubrecht Laboratory has been published and distributed. Copies are still 

 available on request.

IV The Normal Table of Xenopus laevis 



The descriptive work will be ready by the end of 1954. Taking into account 

 the considerable amount of editorial work involved in making the joint manu- 

 script ready for the press, we expect that the Normal Table will appear in the 

 second half of 1955. 



Communications of tlie „Institut International J'Embo ologie" 

 (Embryological Section of the l.U.B.S.) 



The I. I.E. has to announce with regret the loss of two of its founders and 

 honorary members: Prof. Dr. J. P. Hill, who died in London in the beginning 

 of 1954, and Prof. Dr. F. Hochstetter, who died in Vienna on the 10th of 

 November, 1954. at the age of 93. 



Attention is drawn to the fact that, according to the new statutes of the 

 I. I.E.. all persons active in research in the field of morphogenesis may apply 

 for membership. Election to membership is by simple majority of the General 

 Assembly upon recommendation of two fellows and approval by the Board. 



As the next General Assembly will be held in the summer of 1955 in the 

 U.S.A. (date and place will be announced later), applications for membership 

 are awaited by the Secretary, Prof. Chr. P. Raven, Zoological Laboratory, 

 Janskerkhof 3, Utrecht. Candidate-m.embers -may tender their applications 

 personally to the above address; they are advised to secure the recommen- 

 dations of two fellows of the I.I.E. A list of fellows is to be found in the 1952 

 issue of the G.E.I. S. _ ,.^.., 



The Secretary, Chr. P. RAVEN
