nective-tissue cells. From the primary villi small secondary non- 

 vascular villi are frequently given off. 



The larger blood-vessels of the joint capsule lie in llic outer layer 

 of the stratum sync)\iale whence smaller \-essels and caj)illaries pass 

 to the inner layer and to some of the villi. The inner layer is richly, 

 the outer layer more poorly supplied with lymph capillaries. Non- 

 medullated nerve fibres are found in the connective tissue, some of 

 them ending in end-bulbs or Pacinian corpuscles (p. 439). 



TECHNIC 



(i) Joint Capsule and Articular Cartilage. — Remove one of the small joints 

 — human or animal — cutting the bones through about one-half inch back from 

 the joint. Treat as in technic i, p. 202, making longitudinal sections through the 

 entire joint. 



(2) Synovial \'illi. — Remove a piece of the capsular ligament from near the 

 border of the patella and cut out a bit of the velvety tissue which lines its inner 

 surface. Examine fresh in a drop of normal salt solution. Fix a second piece 

 of the ligament in formahn-Miiller's fluid (technic 6, p. 7), make sections per- 

 pendicular to the surface, stain with haematoxylin-eosin (technic i, p. 20), and 

 mount in balsam.
