PREFACE. 



As this manual is intended for dissecting-room use, the 

 body has been considered as divided into the five parts 

 usual in the dissecting-room, viz., head and neck, thorax, 

 upper extremity, abdomen and pelvis, and lower extremity. 

 Each of these parts has been subdivided as much as pos- 

 sible, with regard to the avoidance of excessive repetitions, 

 and described completely. The spinal cord has been de- 

 scribed under the heading of the cranial cavity, because it 

 seemed best to include it with the brain. A special sub- 

 division has been made of the scalp, because of the necessity 

 of early removal of the skull cap in order to preserve the 

 brain. In the text the name of each muscle has been begun 

 with a capital, e.g., Pectoralis major. Because of the great 

 irregularity in origin and course of the smaller arteries, only 

 their distribution has been fully described, as a rule. Cunning- 

 ham's Anatomy has been followed strictly throughout, and the 

 bracketed numerals at the end of each paragraph refer to the 

 corresponding page in the last edition of that Anatomy, e.g., 

 [104]. The bracketed numerals in the body of any par- 

 agraph refer to pages in this manual, e.g., (page 47).
