based on actual models made from serial sections with a special technique. 



The basic plan of the book is such that each time the coloured plate appears 

 on the right-hand page, the left-hand page showing an outline drawing with 

 legends indicating the various structures. 



The plates have been prepared and reproduced with the utmost artistic 

 and technical skill. 



Except for a preface and introduction in German and English there is no 

 text. The introduction explains, among other things, what is meant by the 

 term "kinetic anatomy" used in the subtitle of the work. The superbly printed 

 book is concluded by a list of references and an extensive index to anatomical 

 names. 



3. DIE ENTWICKLUNG DES HOHNCHENS IM EI

This booklet is in fact a reprint from "Zentralblatt fur Veterinarmedizin", 

 IX (4), (pp. 371 — 396), but it is separately obtainable from the publishers. 

 It is a photographical atlas presenting the entire development of the chicken 

 within the egg, shown at consistent intervals of one day (days calculated 

 from the beginning of incubation). All photographs are at the same magni- 

 fication, viz. 4/5 natural size. The eggs are shown after removal of the egg 

 shell and the various membranes in several steps, viz. a) part of the egg shell 

 and its membranes, b) chorio-allantois, or outer lamina of the allantois, 

 respectively, c) amnion and part of inner lamina of the allantois, d) the entire 

 egg shell. In all these steps the embryo is left untouched. Finally the isolated 

 embryo is shown from the third day onwards. In the first four days details 

 of the embryo and its circulation are elucidated by drawings at the same scale 

 as the photographs. 



It will be clear that with the use of one-day intervals, and of a unitary 

 scale of magnification, the series cannot provide an appropriate picture of 

 the early phases of development. This, however, has been done in the existing 

 avian normal tables, and the present series must be regarded as complem- 

 entary to these. The series may prove to be valuable particularly as regards 

 the later development of circulation, and the changing spatial relationships 

 inside the egg. 



The photographs are of good quality, although they have of course 

 sometimes lost important detail in the process of reproduction. In such 

 instances elucidation is provided by the text accompanying each stage. From 

 the 6th day onwards exact length measurements are provided for the embryos.
