PREFACE TO FIFTH EDITION 



THE main object of this preface is to thank those who have 

 so kindly assisted me in the production of the book. At the 

 same time, it may be pointed out that the reasons for the 

 adoption of the Basle nomenclature were fully stated in vol. i., 

 and that the alterations which have been made in the plans 

 of dissection in vol. ii. are not less numerous than those made 

 in vol. i. The alterations include changes in the method of 

 dissecting the face, the posterior triangle, and the deeper 

 parts of the neck. Two plans of dissection to display the 

 middle ear and its surroundings are described. They can be 

 carried out on opposite sides of the head, and the steps of 

 the second method are those followed by the surgeon operat- 

 ing for the relief of mastoid and middle ear disease. The 

 dissection of the thorax has been very largely re-arranged 

 with the object of giving the dissector an opportunity of 

 studying the relative positions of the organs in the medi- 

 astinum whilst they are practically undisturbed. 



The various plans of dissection described were decided 

 upon, after many trials, as those best adapted to give the 

 student a clear idea of the relative positions of important 

 structures ; and I am greatly indebted to my first and second 

 assistants, Dr. E. B. Jamieson and Mr. T. B. Johnston, and 

 to Professor R. B. Thomson of Cape Town, for the trouble 

 they have taken and the help they have given in devising, 

 modifying, and testing new plans of work. 



I am indebted also to Dr. Jamieson for dissections of the 

 brain and heart ; to Mr. Johnston for the dissections of the 

 parotid gland ; to Mr. W. W. Carlow for a dissection of the 

 mediastinum ; and to M^SJ^S, JX^ J^useghian, R. C. Rogers,
