 (von Recklinghausen). In the cornea and serous mem- 

 branes these spaces 

 possess the shape 

 of branched lacu-

 being the home 

 of the body of 

 the cell, while the 

 branches or cana-

 processes. These

 with one another 

 (Fig. 26). The cell 

 and its processes do 

 not fill up the la- 

 cuna and its canali- 

 culi. In loose connective tissue the lacuna may be of 

 considerable size, and may contain several connective 



cells, which make as it 

 were a lining for it. 

 These in some places are 

 very little branched, and 

 almost form a continuous 

 endotheloid membrane of 

 flattened cells. Such is

Several fine tendons are shown here. The dark 

 branched corpuscles correspond t<> albuminous 

 cement substance stained with gold chloride: 

 they are the channels between the bundles of 

 fibrous tissue, constituting the tendon, and seen 

 here as the clear spaces in cross section. In each 

 of these channels is a row of tendon cells not 

 discernible here, the long axis of these rows 

 being parallel with the long axis of the tendon.
