Table 14. — Showing the results of the mating indicated above. 



From the data presented in Table 14 it is clear that one-half of the 

 progeny from this cross were black and one-half were barred; and 

 that the black and the barred birds were about equall}^ divided 

 between the sexes. Similar results were obtained from mating the 

 cross-bred d^, 325 B, ^\ith Black Hamburg 99. One of the cTcf, 

 477 V, resulting from the Black Java cross, was mated in 1913 with a 

 pen of barred 99. This mating is considered in Case 5, p. 203. 



Case 4. — White Leghorn d^ X BJacJ: Java 9 . Nature of mating: 

 CCBBffll X CChbFfii. (For discussion, see p. 186). 



In other series of crosses bred in 1911, 1912 and 1913, the W. L. d^, 



193 A, used in the previous experiments, was mated with several 



B.J. 99. 



Black Java 9, 187 A: Weight 7| lbs., good form but 

 shghtly lacking in breast; beak black shading into yellow at 

 base; eyes hazel; ear-lobes are three-fourths white; wattles 

 red; small amount of purple barring on feathers of neck, wing 

 coverts and tail coverts; primaries, secondaries and main tail 

 feathers are dull black; under-color dark slate; shanks and 

 feet yellow. The other Black .lava 9 9, 188 A, 230 A and 

 231 A, resembled the bird described above in all important 

 points. 



The result of this series of matings shows that as in earlier cases the 

 white of the W. L. was dominant over the black of the Java; fur-
