11. M. gluteus maximus, 0-23 oz. 



Arises from the line marked (Fig. 32, gl. mx.) at the acetabular promi- 

 nence of the ilium. 



1 2. If. glutceus medius, 



2- 05 oz. 

 Its origin and insertion 



are marked in Figs. 32 

 and 33, gl. md. 



13. If. glutceus minimus, 



0-25 oz. 



14. M. glutceus quartus 

 (iliocapsularis), 



0-23 oz. 

 The origin and inser- 

 tion of these muscles are 

 marked in Figs. 32 and 

 33, gl. mn. and il. cp. 



15. M. biceps femoris, 



3- 80 oz. 

 The origin of this mus- 

 cle on the postacetabular 

 surface of the ilium is 

 marked in Fig. 32 ; and 

 it is inserted by the usual 

 pulley at the back of the 

 outer head of the gas- 

 trocnemius into the tu- 

 bercle of the fibula. 



16. M. semimembranosus, 



2-30 oz. 



Arises from the posterior 

 portions of the ilium and ischium (Fig. 32, s. m.) ; and is inserted partly 

 by a tendon into the top of the linea aspera, and partly by a tendon, which 

 is aided (as in the Emu) by an accessory muscle, and which itself has a 

 double insertion by means of two flat tendons into the head of the inner 

 gastrocnemius, and into the middle point of the broad insertion of the se- 

 mitendinosus into the tibia. 



N". B. — This muscle, as already noticed, is connected with the ad- 

 ductor magnus by a tendinous slip. 



17. M. semimembranoso accessorius, 0*50 oz. 



This muscle is shown in Fig. 34, and its general arrangement and 

 connexion with the semimembranosus are similar to those already de- 

 scribed in the case of the Emu.
