DESCRIPTION OF PLATES. 315 



i, A lymphatic vessel formed from the gland H, which passed 

 on to communicate with other lymphatic vessels, not expressed 

 in this plate. 



G, A lymphatic vessel. 



FIG. 3, Exhibits the manner in which a single Lymphatic Vessel 

 enters and passes through a Lymphatic Gland. 



a, The trunk of a vessel filled with mercury. 



b, The division of the trunk into four branches before it 

 enters the gland. 



c, The gland, with the lymphatic vessels passing through it. 



d, The lymphatic vessels having passed through the gland, 

 form four vessels on the opposite side, to which they had 

 entered the gland. These vessels unite to form the trunk e. 



<?, The lymphatic vessel, having passed through the gland, 

 is become larger than before it entered the gland. 



FIG. 4, Exhibits a Lymphatic Gland with the Lymphatic Vessels 

 injected with Mercury, in which the Subdivision of the 

 larger Vessels into smaller Branches, running in a ser- 

 pentine Direction through the Gland, is apparent to the 

 naked Eye. 



FIG. 5, Exhibits Lymphatic Vessels and Glands, taken from 

 the Axilla in which the Subdivision of the Trunks into 

 Branches, and their frequent communication with each 

 other, may be traced distinctly. 



a, a, a, The trunks of five lymphatic vessels that come from 

 the arm into the axilla, and as they ascend, divide into many 

 branches, which make frequent anastomoses, and then form 

 the plexus A. 



A, A plexus of lymphatic vessels dividing into two parts b, c.
