call were also associated. Hybrid birds of Swinhoe type have the 

 Svvinhoe challenge and voice, hybrid birds of Silver type have the Silver 

 challenge and voice. 



A habit of visiting the pheasantry every morning at six o'clock has 

 rendered the task of recording the varying calls an easy one, and as 

 hybrids and pure races are, though separately penned, all in the same 

 field there is amjjle opportunity for comparison.

Summary. 



1. The more the data of these experiments in pheasant cross 

 breeding are examined the clearer and more certain becomes the 

 conviction that they jjroceed on definite lines, subject to some fixed law, 

 certain experiments repeated have shown that the male parent always 

 transmits the female characters of his species to his female offspring 

 and the female parent transmits to her male offspring many of the male 

 characters of her species. The female parent has likewise transmitted 

 the male characters of her species to her female offsjjring in one or two 

 areas, and in many areas in the case of male-assuming female oft'spring 

 (sterile hybrids).
