General remarks. 



We bring to your attention that the chapter "Short notes and 

 references to new technical methods" has been omitted 

 because of lack of sufficient interest. 



This year there are no recently appeared text-books to be 

 reviewed, but we are still very eager to receive copies, or suggestions as 

 to titles, of newly appeared books which you might think suited for reviewing 

 (vid. chapter ...). Our suggestions concerning an annual survey of 

 the embryological literature may this year be found in the 

 section concerning the Central Embryological Library (vid. chapter ...). 



We can announce with pleasure that the number of subscribers as well as 

 that of collaborators, is still rising steadily, i) There is, however, still a small 

 number of institutes which, though regularly sending data, have not yet 

 subscribed. We hope that we may get subscription-orders of most of them 

 in the course of this year, the year in which we may say that the G.E.I.S. 

 has firmly established itself as an indispensable help and guide to all 

 embryologists.

(for Dr P. D. Nieuwkoop) 



1) This year an important number of data from newly cooperating institutes has come in 

 from Japan. We regret not to have received any data from S. -America and India this year. 

 In future we hope again to be able to give data from Indonesia.
