Cats. — If characteristics are for the most part inherited entire and 

 can be combined in various ways, like atoms in chemistry, it should 

 be possible to obtain any desired combination. At the beginning of 

 the 3'ear I set myself the task of producing a white, blue-eyed, deaf, 

 long-haired, tailless, poly dactjd cat. M}^ parental stock consists of : 

 No. I, black Manx male (tailless) ; No. 2, black, tailed, polydactyl 

 female ; No. 3, female Maltese polydactyl ; No. 4, white, blue-eyed, 

 deaf, polydactyl female ; No. 5, black and yellow polydact3'l female. 

 The Manx male was bred to these females. The results so far are 

 represented below in tabular form.
