The first chapter containing much new material is that on DNA replication 

 (ch.9). From ch.l4 onwards this becomes the rule. There are two new chapters: 

 The essence of being eucaryotic (42 pp.) and The control of cell prolifera- 

 tion (44 pp., but incorporating material from original earlier chapters). 

 The chapter on cancer has been completely reshuffled and greatly extended. 

 The advances in molecular embryology (ch,17) are well covered. Only the very 

 latest developments such as teratocarcinoma work and the H-Y antigens are 

 missing. 



The lay-out of the book has been modernised, there are 185 more figures 

 than in the previous edition, and all the figures have been re-styled.

The four contributions in this book are exhaustive reviews of recent bio- 

 chemical work centered on different, well-characterised insect gland sys- 

 tems: the silk gland of Bombyx (Suzuki, 45 pp.); the follicular epithelium 

 and its products (particularly the egg shell) in various insects (Kafatos 

 and many other authors, over 100 pp.); the salivary gland of Cht-ronomus 

 (Grossbach, 50 pp.); and the salivary gland of Aor-iootopus (Baudisch, 16 pp.) 



All chapters are well organised but their format and scope is quite dif- 

 ferent. The second is almost a monograph in itself and sketches in a lot of 

 background of a general nature. It also has sections on the comparative 

 morphology and chemistry of insect chorions, on the chemical morphogenesis 

 of the silkmoth chorion, and on chorion mutants in Bombyx. Apart from silk- 

 moths Dvosoph-ila is considered in a separate section of some ten pages. 



The first three chapters are up to date until 197 5/76, the last until 1974. 

 The book is very well illustrated.
