 There are other elements in the blood in addition to 

 the foregoing, but these are not of sufficient interest 

 to anyone, excepting those engaged in professional 

 work, to enumerate herein. 



(c) Absorbent Vessels and Glands [Lymphatic 

 System). — Throughout the body there is a system of 

 vessels (and glands) which convey a fluid known as 

 lymph, or chyle, which is taken up by these vessels as 

 a balance remaining unused by the blood. Two main 

 trunks carry the lymph into a large vein at the base 

 of the neck. The thoracic duct is the main lymphatic 

 vessel, and the smaller ones communicate with it. 

 It begins under the loins and ends at the base of 

 the neck in a large vein as previously stated. The 

 lymphatic glands are very numerous throughout the 

 body, some being situated internally, others quite 

 superficially. 



These glands are largely concerned with the 

 formation of the colourless blood globules, and 

 readily arrest disease-producing germs, hence the 

 reason why these structures are nearly always 

 early affected in such maladies as tuberculosis, dis- 

 temper, etc. 



The lymph is aided in its circulation by the 

 muscular movements of the body.
