Although this new edition of a well-known book has been revised and somewhat 

 extended, it has essentially remained the same book. While 20 years ago a synthesis of 

 comparative and experimental vertebrate embryology was still feasible, so much has 

 happened since in developmental biology (I do not even mention molecular embryology) 

 that it would now be impossible, at least at the level of detail aimed at here. 



Since no consistent attempt has been made to incorporate even the most important 

 advances, the book is now decidedly dated and conveys very little of the present-day state 

 of embryology. Much of the Uterature is by now very old and could have been sifted to 

 yield space for exciting new discoveries and approaches. The book undoubtedly has had 

 its uses in the past, and many sections will continue to be useful for further study of 

 specific topics. However, there are now more modern textbooks on the market, which are 

 inevitably more selective but also much more balanced in their treatment.

This photographic atlas is intended for the use of those active in poultry research. Its 

 usefulness for embryologists is limited. The stages, particularly those of early develop- 

 ment, are widely spaced. The second part, illustrating some genetic and environmentally 

 induced defects and diseases, is clearly meant for the practical chick breeder. The colour 

 photographs are of reasonable to good quality but some of the earlier stages (3-6 days) 

 are difficult to discriminate.
