development in the embryo and on feathers and their development. 

 The chapter on mammals contains sections on fetal epidermis and 

 on the three phases of the hair growth cycle. 



The booklet is superbly illustrated with electron micrographs 

 and half-tone drawings.

It is fitting that this volume should be dedicated to Ernst 

 Hadorn. The dedication is by D.Bodenstein and accompanies a de- 

 lightful portrait of the great Swiss biologist. All the contrib- 

 utors have at one time been associated with Hadorn. 



The six reviews making up the volume are comprehensive and 

 well organized, and as up-to-date as is possible in such a book. 

 There is some overlap between the chapters, but this is inevita- 

 ble and suitable cross references are provided. The subjects 

 treated successively are larval development (Nothiger), the sta- 

 bility of the determined state (Gehring), pattern formation 

 (Garcia-Bellido) , fine structure (Ursprung), biochemistry (Fris- 

 trom), and hormonal control (Oberlander ) . The chapter by Gehring 

 is a revised and updated version of an article that appeared in 

 vol.1 of this series. Several chapters contain unpublished work; 

 this holds particularly for Fristrom's chapter, which is the 

 first published review in this area and clearly brings out the 

 molecular-biological parallels between imaginal disc development 

 and embryogenesis in other species. 



The book is produced and illustrated in the usual excellent 

 manner, but as in the other volumes of the series the absence of 

 indexes is regrettable.

Volume I of this multi-author research monograph was reviewed 

 in Gen. Embryol. Inf. Serv. Suppl.l_4, 1972, p. 34. The present 

 volume is in three parts, the first dealing with embryo and organ 

 culture (3 chapters), the second with various applications of in- 

 vertebrate tissue culture (7 chs.), and the third being a cata- 

 logue of invertebrate cell lines compiled by Hink (with formulas 

 of 22 culture media). 



All three chapters in part one are of interest to developmental 

 biologists. Demal and Leloup deal with insect organ culture with 

 particular reference to morphogenesis (38 pp.); they pay special 

 attention to the brain and the eye-antennal imaginal discs, the 

 thoracic discs, the circulatory and digestive organs, and the 

 gonads. Gomot reviews organ culture in invertebrates other than 

 insects, arranged according to nine major phyla (95 PP«)j the 

 chapter has several sections on the culture of regeneration 

 blastemas. Finally Takami deals with insect embryo culture in a 

 review centered on Bombyx mori (27 pp.). 



In part two the following chapters may be mentioned: Barigozzi 

 on cell culture in genetic research (centered mainly on Drosophi- 

 la), and Berreur-Bonnenfant on organ culture in hormonal research
