PREFACE TO THIRD EDITION. 



THE first edition of this work was written by the late 

 Dr. Le Roy Lewis upon the request of many of those 

 whom he had instructed in anatomy and physiology. 

 He endeavored to make the text as simple and com- 

 prehensive as possible, so that students might be able 

 to grasp the primary principles, after which he felt that 

 they would be sufficiently equipped to apply themselves 

 to future studies. 



The works of Gray, Wilson, Deaver, Brubaker, Kim- 

 ber, and others were freely consulted, and in some in- 

 stances their language was employed or paraphrased. 

 The publishers furnished many illustrations, which eluci- 

 date the text and aid the student in grasping the details 

 of the subject. 



Owing to the gratifying reception accorded the pre- 

 vious editions of this work, the present editor has not 

 deemed it wise to depart materially from the general 

 plan and manner of presenting the subject. Some por- 

 tions have been rewritten, considerable new matter has 

 been incorporated, and the entire book has been thor- 

 oughly revised. It is hoped that this new edition will 

 be found to be particularly adapted to the needs of 

 students and practitioners of nursing.
