THE MUSCLES OF THE LOWER EXTREMITY. 195 



composed of rather coarse carneous fibres. It arises 

 from a line on the lateral aspect of the pelvis, which 

 line constitutes the lower boundary of the ischia tic- 

 fossa that contains the obturator cxternus muscle. The 

 extent occupied on this line by the adductor longus 

 is equal to the length of it between the obturator 

 foramen and a point rather posterior to the ischiatic 

 foramen, in the vertical line. Here it is met by the 

 adductor magnus, the anterior point of its origin. By 

 an oversight in Fig. 24, the relative positions of the 

 orio-ins of the semitendinosus and the two adductors are 



o 



in each case a little too far forward to agree with what 

 we find in the majority of specimens. This has been 

 corrected, however, in the figures illustrating these 

 muscles, and in the several descriptions. 



generally, however, they have been considered as one muscle, and 

 Gadow records the following synonymy for them (loc. cit., p. 174) :
