348 Antisera for Birds Eggs 



In this as in the last table the results of quantitative and qualitative 

 experiments closely correspond. Egg-albumins from the Duck's to the 

 Moorhen's in the above list were shown by qualitative tests to produce 

 full reactions. By the latter method a medium clouding occurred with 

 Thrush egg-albumin, and small cloudings with the albumins of the 

 Emu and Hedge-sparrow. 



(3) Tests with Anti-Fowl' s-Egy Serum. 



Thrush, Emu, Greenfinch, and Hedge-sparrow egg-albumins were 

 tested and gave traces of precipita, as also did Tortoise and Turtle sera. 

 The egg-albumins of the Tortoise, Frog, Skate, and two species of Dog- 

 fish did not react. Alligator, Frog, Amphiuma and Dogfish sera also 

 yielded no results. 



As before the quantitative and qualitative methods closely agree. 

 By the former method full reactions were recorded with Fowl and Silver 

 Pheasant egg-albumins, marked reactions with Pheasant, Crane and 

 Blackbird, medium with Duck, Thrush and Greenfinch, and small with 

 Moorhen, Emu and Hedge-sparrow.
