 these are: The right hypochondriac, right lumbar, right 

 inguinal, epigastric, umbilical, hypogastric, left hypo- 

 chondriac, left lumbar, and left inguinal. The division, 

 as will be seen from the illustration, is made by draw-

 ing it into regions : 1, Right hypochondriac region ; 2, epigastric ; 5, left 

 hypochondriac ; 4, right lumbar; 5, umbilical ; 6, left lumbar; 7, right iliac ; 

 8, hypogastric ; 9, left iliac (Chapman). 



ing an imaginary line horizontally between the car- 

 tilages of the ninth ribs; another between the crest of 

 the ilia; and two vertical lines from the cartilages of 

 the eighth ribs to the center of Poupart's ligament.

 lobe of the liver, the gall-bladder, the duodenum, the
