Description:

'albinism tends to be less & less perfect, and, I believe, it will be possible ultimately to obtain almost any grade of albinism. I have at present  a bitch with one normal and one albinotic eye, and a brown skewbald coat, Choo Ko, or ‘Wan eye’. Mated with her own father, however, she has not yet perpetuated her hetero-chromia, but given me three skewbald puppies, one of whom Ming Wang, I show you tonight. He has imperfectly pigmented mucous membrane – the liver colour. Choo Ko is like our Dondos a piebald Pekingese directly descended from Ah Cum & Goodwood Meh on one side.' (f. 16)
