PREFACE. 



THE plan of this work is designed to teach the Anatomy of the 

 Human Body by dissection in successive stages after the following 

 manner : 



In the dissection of a Part the attention of the Student is directed 

 first to the superficial prominences of bone and muscle, and to the 

 hollows that point out the situation of the subjacent vessels. Next 

 the cutaneous structures, and the different layers of muscles with 

 their appertaining vessels and nerves are examined in succession, so 

 that the several objects between the surface of the Body and the 

 bones may be observed in much the same order as they would be 

 met with in a Surgical operation. And, lastly, the joints and liga- 

 ments receive due notice. 



In the dissection also of the viscera and the organs of the senses 

 the manner in which the composition of each may be shown, is fully 

 indicated for the guidance of the Student. 



The Anatomical description of the Part under examination is 

 arranged in conformity with the dissection in regions, and each 

 muscle, bloodvessel, nerve, or other structure, is described only to 

 such an extent as it may be laid bare. 



Since the publication of the last edition great changes have been 

 made in textural Anatomy; and the chief of these, for which I am 

 indebted to Quain's Anatomy, I have introduced into my account of 

 the microscopic structure of the different organs. 



In this edition, as in the preceding ones, I have endeavored to 

 make the work more complete by the correction of inaccuracies, and 

 to render it more efficient as a guide to practical work.
