Terminology 15 



Predpitin is used to include the antibodies contained in lactosera, called 

 "coagulins" by some authors. The term "serotoxin" (corresponding to cytotoxin) 

 su posted by Nedriagailoff (11. vm. 1901) will scarcely receive acceptance. Sera 

 containing precipitins for blood are referred to frequently as haetuatosera. 



Complement is used synonymously with addiment (Ehrlich), alexine, cytase (of 

 French authors). 



Immune-body is used synonymously with Amboceptor, Immunkorper, Prii- 

 parator, Copula, Desmon, Hilfskorper, Zwiscbenkorpcr (of German authors), 

 Fixateur, substance sensibilisatrice or preventive specifique (of French authors), 

 Fixer, and Go-between (of English authors). 



Intermediary-body is confined in its use to the corresponding substance to the 

 foregoing, which is found in normal sera, and corresponds to Ehrlich's " Zwischen- 

 korper."
