Tests with Precipitins 



titative, in Section VIII. In my preliminary communication of 20, i. 

 1902, 1 reported that I had tested 250 bloods with the result that those 

 of Alligator mississippiensis and A. sinensis gave reactions, a clouding 

 occurring in the blood of Chelone midas. The tests with the alligator 

 and turtle sera were repeated several times with uniform results, these 

 being included in the tables.
