which is composed of larger vessels (of 0*01 — 0005 ' ) with 

 wide, and of capillaries (of - 003 — 0-005"') with narrow meshes ; 

 and secondly, of very 

 many separate loops 

 of the finest vessels 

 (0-003— 000 i'") which 

 are given off to the pa- 

 pilla. With certain ex- 

 ceptions (i?.§ 37) every 

 papilla possesses its 

 own capillary loop (fig. 

 53), (the branched 

 papilla have many), 

 which runs, either in 

 the axis of the papilla or near the surface, almost as far as its apex. 

 The larger trunks of the lymphatic vessels are very easilv 

 recognisable in the subcutaneous cellular tissue, and are verv 

 numerous. In the corium itself different anatomists, Haase, 

 Lauth, Fohmann, &c, have demonstrated the lymphatics by
