Embryopathies may be defined as more or less extensive lesions of the 

 embryo as a result of virus infections of the mother during the first three 

 months of pregnancy. Embryopathies should be distinguished from other 

 pathological phenomena in the prenatal period. 



In the present book an exhaustive treatment is presented of all that has 

 become known about embryopathies since their first discovery, about 20 

 years ago. It is natural that the stress should lie on the best investigated case, 

 embryopathia rubeolica, but the effect of several other virus diseases are also 

 discussed. Much of the material is original and published here for the first 

 time. Moreover, the book contains a section on general aspects of prenatal 

 pathology, and a chapter discussing the experimental data concerning the 

 action of viruses on embryos of various laboratory animals. 



The book is illustrated with numerous photomicrographs. The bibliography 

 is entirely up-to-date.

In this monograph the comparative embryology of thirty species of Odonata 

 is studied. They represent all the different famihes of the three suborders of 

 Odonata known in Japan (Zygoptera, Anisozygoptera, Anisoptera). The dis- 

 cussion is based on an extensive description of the embryonic development of 

 Epiophlebia superstes (Anisozygoptera). After a historical rewiew of the 

 embryology of Odonata the reader finds chapters on materials and methods, 

 oogenesis, organization of the egg, maturation and fertilization, cleavage, yolk 

 cells, blastoderm, pole cells, development and movement of the germ-band and 

 embryonic diapause. By far the largest chapter is concerned with organo- 

 genesis (98 pages). Finally the embryological relationships between the three 

 suborders mentioned are discussed, as well as those between the Odonata 

 and other Insects. The bibliography covers 12 pages. The author has tried to 

 include all papers published after the appearance of the work of Johannsen 

 and Butt on the embryology of Insects and Myriapods (1941). In an adden- 

 dum newer papers up to 1961 are discussed. The book is illustrated with very 

 clear line drawings and a few photographs.
