DEVELOPMENT OF THE CHICK HEART

This atlas is based on a study conducted at the Laboratory of 

 Embryology of the Instituto Nacional de Cardiologia de Mexico. 

 It contains 19 composite full-page plates printed on high-quality 

 paper, each accompanied by a concise text. The developmental pe- 

 riod covered is from 26 hrs. till hatching, comprising 18 stages 

 of the Hamburger/Hamilton series selected to show the most con- 

 spicuous changes (the first stage being st.8 and the last st.44). 

 Separate plates are devoted to the heart and great vessels in 

 the newly hatched chick, and to the formation of the interatrial 

 septum. Until st.32 most plates include good diagrams illustra- 

 ting the embryonic human heart at comparable stages, mostly 

 taken from classical sources. Up to and including st.22 the 

 chick embryos were stained and photographed as whole mounts, 

 thereafter the fixed hearts were photographed in toto or after 

 partial microdissection, as seen from various sides. 



The text, based on personal observations only, is clearly 

 written and contains references to those developmental disorders 

 which give rise to the most common congenital heart defects. 



The illustrations are of outstanding quality and are clearly 

 labelled. The book is concluded by a brief selective bibliogra- 

 phy. The production is luxurious but the format somewhat un- 

 wieldy; the price is surprisingly low thanks to a Mexican grant.
