Preface to the Eighth Edition 



IN the preparation of the eighth edition of the Practical Anatomy 

 of the Rabbit use has been made of extensive notes recorded in the 

 laboratory during successive years of employment of the previous 

 edition. All relevant questions raised by students or other in- 

 structors for which an adequate answer was found not to be readily 

 available in the text have been noted and an attempt has been 

 made to provide answers for them in the revisions. Criticisms 

 received have been carefully considered and the whole text has been 

 searchingly surveyed, with the result that many small changes 

 have been made, parts (e.g. the description of the larynx) have 

 been expanded, and a few have been entirely rewritten. New 

 sections have been added, for example, one on the foetal circulation. 

 A considerable number of new^ illustrations have been included, 

 some replacing ones which were felt to be unsatisfactory, but the 

 total number in the book being further increased from 114 to 124. 

 Functional aspects as well as developmental ones have been 

 consistently emphasized. 



Since some classes study briefly the microscopic structure along 

 with the gross anatomy, the early chapter on "General Anatomy" 

 has been somew^hat expanded. For suggestions regarding this and 

 for provision of some of the photomicrographs the writer is in- 

 debted to the co-operation of Dr. V. E. Engelbert. For the new 

 figure 58 he is indebted to the kindness of Dr. C. C. Macklin. 

 To these and to other colleagues from whom helpful comments 

 have been received he wishes to express his gratitude.
