RELATION OF LYMPHATICS TO COXXECTIYE TISSUE.

which they more or less completely fill. These cells and cell-spaces 

 form in many parts an intercommmiicatino- network of varying fineness 

 extending throughout the substance of the tissue (fig. 126, d, d), whilst

a, Lymphatic vessel ; i, artery ; c, capillaries ; d, branched cells of the tissue which 

 are seen to be connected both with the capillary -walls, and, as at e, with the lymphatic. 



in other parts the cells acquire a broad flattened form, and joining edge to 

 edge with other similar cells may in this way form an epithelioid patch 

 in the ground-substance. Not unfrequently the cells in such a patch 

 take on the wavy border described above as met with in the lymphatics 

 of origin (see fig. 124). Further, the flattened cells which form the 

 walls of the latter vessels are connected here and there both with the 

 more isolated cells of the tissue (fig. 126 e) and with those which form 

 the epithelioid patches, and in silvered preparations they appear to be 

 continuous with one another. The epithelioid patches look in fact 

 like a part of the lymphatic, and are commonly regarded as such : it 

 must be understood, however, that the spaces here spoken of, whether 

 containing single cells or groups, are not true vessels, but merely vacui-
