PREFACE TO THE PEESENT EDITION. 



IN the present edition the work has been again care- 

 fully revised throughout ; certain sections have been 

 re-written, and much new matter has been added. 

 Every effort has been made to bring each chapter of 

 the book well up to date. Two new woodcuts have 

 been inserted in the place of old ones. These have 

 been derived from my " Manual of Operative 

 Surgery."
