 niagnus muscles, and the capsular ligament of the thigh bone. 



2. One between the tendon of the pectinalis muscle and the 

 thigh bone. 



3. Between the gluteus medius and trochanter major, and 

 before the insertion of the tendon of the pyriformis. 



4. Between the tendon of the gluteus minimis and trochanter 

 major. 



5. Between the gluteus maximus and vastus externus. 



6. Between the gluteus medius and pyriformis. 



7. Between the obturator internus and os ischium. 



8. An oblong bursa continued a considerable way between the 

 obturator internus, gemini, and capsular ligament of the thigh 

 bone. 



9. A small bursa at the head of the semimembranosus and 

 biceps flexor cruris. 



10. Between the origin of the semitendinosus and that of the 

 two former muscles. 



11. A large bursa between the tendon of the gluteus maximus 

 and root of the trochanter major. 



12. Two small bursas between the tendon of the gluteus 

 maximus and thigh bone. 



About the Joint of the Knee are, 



1. A large bursa behind the tendon of the extensors of the 

 leg, frequently found to communicate with the cavity of the 

 knee joint. 



2. Behind the ligament which joins the patella to the tibia, 

 in the upper part of the cavity of which a fatty substance 

 projects. 



3. Between the tendons of the sartorius, gracilis, semitendi- 

 nosus, and tibia. 



4. Between the tendons of the semimembranosus and gemel-
