PREFACE 



TO 



THE THIRD EDITION. 



IN the present Edition the author adheres to his 

 decision not to introduce Diagrams. Additional 

 experience more than ever convinces him that they 

 would frustrate his original object, which is to teach 

 Students the habit of making the eye and the hand 

 work together, and to educate the ' touch ' upon the 

 normal living body. 



Without such practical training, how can we 

 reasonably expect to form a correct diagnosis when 

 called upon to examine an injury or to detect a 

 disease ? In truth, the work is intended only for 

 those who are desirous of acquiring the habit recom- 

 mended. 



LONDON: May, 1881.
