186 PHYTOTOXINS AND ZOOTOXINS 



in securing an active antitoxin which neutralized the strongly 

 hemolytic action of eel serum in vitro, and also prevented fatal 

 effects in animals. Camus and Gley l have studied the physio- 

 logical action of eel serum and found it strongly hemolytic, and 

 also apparently neurotoxic. The toxicity is destroyed by heat- 

 ing to 58 for fifteen minutes. By immunization an antitoxic 

 serum can be obtained which neutralizes the eel toxin com- 

 pletely. Tchistovitch 2 secured antitoxic serum, which acted 

 also as a precipitin for eel serum. De Lisle 3 found that eel 

 serum does not act like an amboceptor, since after heating it 

 cannot be reactivated with fresh serum, and it seems, therefore, 

 to be different from snake serum in its structure.
