situated in the capsule, into the cortical lymph sinuses, 

 from these into the medullary sinuses, and from these 

 into the efferent lymphatics. Owing to the presence 

 of the reticulum in the sinuses the current of the 

 lymph will proceed only very slowly and with diffi- 

 culty, as if it were passed through a spongy filter. 

 Hence a large number of formed corpuscles, pigment, 

 inflammatory or other elements, passing into the gland 

 by the afferent vessels are easily arrested and de- 

 posited in the sinuses, and there readily swallowed by 

 the amoeboid corpuscles lying in the meshes. 



Passing a stream of water through the gland, the 

 contents of the meshes of the reticulum of the sinuses 

 i.e., the lymph corpuscles are of course the first things 

 washed out (von Recklinghausen), and on continuing 

 the stream some of the lymph corpuscles of the 

 follicles and cylinders are also washed out. Hence it 

 is probable also that by the normal stream of lymph 

 passing through the gland, lymph corpuscles are 

 drained, as it were, from the follicles and cylinders 

 into the sinuses. The amoeboid movement of the lymph 

 corpuscles, especially of the large and ripe ones, will 

 greatly facilitate their passage from the follicles and 

 cylinders into the lymph sinuses.

NERVE-FIBRES. 



136. THE nerve-fibres conduct impulses to or from 

 the tissues and organs on the one hand, and the nerve- 

 centres on the other, and accordingly we have to con- 

 sider in each nerve-fibre the peripheral and central 

 termination and the conducting part. The latter, i.e..
