ticked. With the exception of five kittens, the offspring 

 of the much-ticked male (21) are useless for determining 

 degree of ticking on account of the presence of yellow. 

 Three kittens (58.2, 54.3, and 54.4) are little-ticked like 

 their grandfather (18). Two kittens (54.1, 54.2) were 

 much-ticked like their father and grandmother. The 

 mothers of all of these kittens were non-ticked. The same 

 degrees of ticking, ^1'" and A, have been possessed by 

 three generations. 



Skins illustrating the three types of ticking A% A'", and 

 A are preserved for reference. 



The crosses summarized in the preceding paper and 

 above may now be considered from the point of view of 

 white-spotting. Solid-white acts as a complete dominant 

 to other colors as shown in the previous paper. White- 

 spotting as seen among cats in general grades all the way 

 from solid-white to self. In individual fraternities, how- 

 over, it may show wide and clean segregation as the 

 crosses below demonstrate. A ''self" cat may have a 

 winute white spot on breast of belly or a few sparsely 

 scattered white hairs. In this case it might be called 

 near-self. Restricted spotting denotes white on nose, 

 breast, belly, or feet. It segregates widely from near-self 

 in the crosses hero considorod, but grades into moderate 

 spotting, which (b^notos tlic further cxtciisioii of white to

A self male (18) crossed (19, 31) to two self females 

 (19, 14) sired eight self. One of these self offspring (21)
