170 PRACTICAL MICROSCOPY. 



that the follicular cords do not entirely fill the spaces between the- 

 trabeculae, and that the area between the two, i. e., outside the cords, 

 is the more open in texture, and contains the filtering lymph. 

 They are more distinct in the cortex.)

5. The histology of the capsule, (a) The closely united con- 

 nective tissue with the scattering elastic fibres of the external 

 layer, (b) The smooth muscle of the deeper portions, (c) Sec- 

 tions of arteries. (These may present of considerable size.) (d) 

 The lymph spaces. (The differentiation is by the flattened endo- 

 thelia of spaces which otherwise would be supposed mere rifts in the 

 tissue, inasmuch as no definite or special wall can be detected.)
