B. Anti-Grocodiliaii Sera. 

 Testfi with A ntl- Alligator Serum. 



This antiserum was made by Dr Nnttall with the serum of the 

 Chinese Alligatoi- (Alligator sivensis). 



This was a moderately powerful antiserum. It showed maximum 

 reactions with the Crocodilia and Chelonia. One out of the four Birds' 

 egg-albumins tested gave a slight reaction. The tests on the Lacertilia, 

 Ophidia, Amphibia, Pisces, and Arthropoda were carried out on tlie best 

 material obtainable, but all with nesfative i*esults.
