Most of the papers in this symposium report are short to medium-length and 

 are best characterised as progress reports. The specialists will by now have 

 read the definitive publications anyhow, but the book seems well suited to 

 recommend to postgraduate students as collateral reading. The symposium was 

 held in Helsinki, Finland in August 1976 and brought together a representa- 

 tive group of workers in areas that are in the forefront of the developmental 

 and cell biology of today. 



The 24 main papers are arranged in five sections as follows: Early deter- 

 minative events in embryogenesis (4 papers) ; Positional information and 

 morphogenetic signals (4) ; Morphogenetic tissue interactions (7) ; Molecular 

 mechanisms of cell contact interactions (5) ; and Cell recognition (4) . Each 

 section is opened by a concise chairman's introduction clearly setting out 

 the main problems (these are by McLaren, Wolpert, Saxen, Weiss and Moscona) . 



The volume is adequately produced and illuscrated. (Personal remark by the 

 reviewer: in view of the discoveries by Nieuwkoop and co-workers and others 

 on mesoderm induction in the amphibian blastula, I feel it is about time to 

 drop the term "primary induction" and only to use "neural induction".)
