This was one of the most pow^erful of the antisera to egg-albumins. 

 Its maximum effects were produced on the Avian egg-albumins, but 

 well-marked reactions occurred with the egg-albumin of the grass snake, 

 and with the blood sera of three Chelonians (Tortoise (2), Turtle), one 

 crocodile, and one snake. Very feeble reactions occurred w'ith three 

 Chelonians, one lizard, one snake, and one Am})hibian (Toad).
