334 Quantitative Precipitin Tests 



6. Quantitative Tests with Anti- Avian Sera. 



Tests with Anti-Ostrich Serum (11. ui. '02). 



Antiseiuin i'vnux vahh\t treated with the serum of StriitJiio iiiolyhdo- 

 phanes. 



Blood of Date 



740 Struthio molybdophanes. Ostrich 20. xii. 01 



277 Casuarius bicurunculatus. Cassowary 14. xi. 01 



342 Ehea americana. Rhea 25. xi. 01 



511 Pelecanus onocrotalus. Pelican 18. ii. 02 



369 Sarcorhamphus gryphus. Condor 27. xii. 01 



Galhis domestiens. Fowl 25. ii. 02 



590 Anas boscas. Duck. 7. iii. 02 



281 Nyctea scandiaca. Owl. 14. xi. 01 



From the above it will be seen that a considerable reaction was 

 obtained with all the avian bloods tested, the percentage falling in the 

 order given. It must be noted that the bl(wd of Rhea (842) was putrid 

 when received, and that it contained a considerable amount of deposit 

 due possibly to the chloroform, this may account for the low percentage 

 obtained in this case. Although all avian bloods react apparently to 

 anti-avian sera (see qualitative tests) it is evident that there are quanti- 

 tative differences which will require further study. 



Tests with Anti -Fowl Serum (K v]. '02). 

 Antiserum from rabbit treated with the serum of GuJlus dometitiriis.
