: Body of the pubis : The use of this term by English anatomists is a variable one. Macalister, whose 

 terminology here, as usual, is in conformity with that of Continental anatomists, writes : " The pubis consists 

 of a body which forms a little less than one-fifth of the acetabulum . . . "; Quain, on the other hand, 

 writes: " The flat portion between the rami [of the pubis] is the body"; and Young, in his "Synopsis of 

 Human Anatomy " (U.S.), follows Quain's usage. The Continental application of the term has, however, 

 the advantage in the point of consistency, the body being then, in the case of each of the three elements of 

 the hip-bone, the thickened portion taking part in the formation of the acetabulum, of which the body of Ik; 

 tubis constitutes about one-fifth, the body of the iliinn nearly two-fifths, and the body of the ischnim t'n.~ 

 remainder. TR. 



FIG. 313. THE RIGHT HIP-BONE, OUTER SIDE. SEEN FROM THE RiGrtr. 



For this illustration the hip-bone has been so placed that a direct view of the interior of the acetabulum 

 is obtained ; this consists of two portions, the rough, nearly circular fossa of the acetabulum, and the 

 horse-shoe shaped articular surface (facies lunata covered in the recent state with cartilage) ; 

 opposite the fossa of the acetabulum, the rim bounding the depression is interrupted by the cotyloid 

 notch (incisura acetabuli). The three bones which, separate at first, subsequently unite to form the 

 hip-bone, all take part in the formation of the acetabulum (see note l above).
