19. Semitendinosus (Fig. 36), 64-0 



Origin ; from the tuberosity of the ischium. 



Insertion ; by a tendon, one inch broad, into the point of bisection 

 of the tibia. 



20. Gracilis, 45*0 



Origin; from the arch of the pubis and two inches of posterior por- 

 tion of its symphysis. 



Insertion ; into the head of the tibia, by a tendon, three inches in 



length.

22. Vastus externus (Fig. 36), 54*5 



A strong ligament joins the greater and posterior trochanters, under

23. Vastus inter mus, 41*5 



24. Crurceus, 21*5 



25. Poplitaiics, 5'5

Insertion ; into the upper half of the back of the tibia. 



26. Gastrocnemido-solceus, 29 0 



Insertion ; into the os calcis. 



27. Plantaris (flexor per for atus), 3*5 



Origin ; from the back of the outer condyle, covered by gastrocnemius. 

 Insertion ; into the plantar fascia covering the os calcis, from which 



it passes on to the common junction of flexor tendons in the sole of the 

 foot, and ultimately expends its force on the three perforate tendons of 

 the toes. 



N". B. — This seems to be the plantaris and flexor digitorum brew's 

 (perforatus) combined.
