CONCENTRATION OF ANTIBODIES 157 



aqueous humor. Protein precipitins are found in the serum, thoracic 

 lymph, and neck lymph, the concentration being lower in the last than 

 in the first two. 



The immunity is specific in the other body fluids as in the serum. 



The introduction of an immune blood into a normal animal 

 increases the concentration of the bacterial agglutinins in both the 

 lymphs above the normal. The introduction of an immune blood 

 does not increase the concentration of hemopsonins in the neck lymph, 

 altho the concentration in the thoracic lymph is markedly increased. 

 The concentration of bacterial agglutinins and hemopsonins in the 

 cerebrospinal fluid is not modified by passive immunization. 



The passage of antibodies from blood to the lymph is a relatively A 

 rapid process.
