immunobiology in the broadest sense. The contributors were North Americans 

 as well as some Australians. 



Of the 31 papers about one third are of interest to the general zoologist 

 and/or developmental immunologist; most of these are medium-length reviews. 

 In the book as a whole, some papers deal with invertebrates, several with 

 lower vertebrates, one with marsupials, and many with model systems such as 

 the chick, the mouse and the dog. 



The book is produced in photo-offset and is adequately illustrated.

Springer, Berlin, etc. Proceedings in Life Sciences. XIV, 310 pp., 147 figs., 



30 tabs., subject index. DM 58.00, $ ca. 29.00 



This book is based on a symposium held in Paris in 1977. Of the five ses- 

 sions held, only the last is of particular interest to our readers. It is 

 entitled Respiration of the Embryo: Eggshell, Embryonic Membranes, Circula- 

 tion, Blood. It consists of 1 1 short to medium-length research reports or 

 reviews of recent work by contributors from the U.S.A., Japan and various 

 West-European countries. 



Five papers and an abstract deal with various aspects of "egg respiration" 

 particularly gas conductance and egg shell properties. One paper each is de- 

 voted to eggshell formation, development of the avian respiratory and circu- 

 latory systems, gas transfer in the chorioallantois, embryonic hemoglobin, 

 and the effect of restricted gas exchange on embryonic heart rate. 



The volume is well produced and exceptionally well illustrated.

This symposium was held at Montpellier, France in May 1978. The report con- 

 tains 18 brief to medium-length research reports from various medical and 

 agricultural research institutes in France (one from Scotland) . Eleven of the 

 papers are in French but all have English summaries. The research reported 

 was done in man and various laboratory and domestic mammals (one paper on 

 the chick) .

O.HERTWIG. 1977. THE BIOLOGICAL PROBLEM OF TO-DAY, PREFORMATION OR EPIGENESIS? 



the basis of a theory of organic development, translated from the German by 



P.Chalmers Mitchell 



Dabor, Oceanside, N.Y. XXII, 148 pp., 4 figs., combined author/subject index 



and glossary. $ 15.00 



This is a reprinting of the English translation (1900) of Hertwig's influ- 

 ential book Praformation oder Epigenese (1894) . The major part of the book 

 is a critique of Weissmann's theory of germ plasm, and Hertwig reveals him- 

 self as a forerunner of current thought concerning the equipotentiality of 

 nuclei in the organism, coupled with differential activity of the genetic 

 material, as the basis of epigenetic development.
