558 THE RELATION OF COLLOIDS AND LIPOIDS TO IMMUNITY 



Levy. 1 A similar curve is usually found in taboparesis. See table 20a 

 and Fig. 122. 



TABLE 20a-SHOWING THE FOUR COMMON TYPES OF COLLOIDAL 



REACTIONS 



No reaction; normal fluid. 

 Paretic Reaction Type. 

 (Fig. 122.) 



Luetic Reaction Type (Fig. 122). 

 Meningitis Reaction Type. 

 (Verschiebung nach oben.) 



3. The cerebrospinal fluid in tabes dorsalis usually produces the 

 "luetic zone" curve of a No. 4 intensity, as, for example, 4445542000; 

 precipitation being partial in the first two or three tubes, then becoming 

 complete, and gradually returning to normal through the balance of the 

 series. The changes, however, are not constant or characteristic. 



4. The fluids in cerebrospinal syphilis usually yield weak reactions 

 of the "luetic zone" type. In tertiary syphilis without symptoms 

 referable to the central nervous system similar reactions are frequently 

 observed. 



5. Fluids from cases of purulent or tuberculous meningitis may 

 give reactions which are usually maximal in the higher dilutions, the 

 "meningitic zone" type and so-called "Verschiebung nach oben." In 

 acute anterior poliomyelitis the cerebrospinal fluid frequently yields reac- 

 tions similar to the "luetic" and "meningitic" zone types of reactions.
