go, and to my knowledge for at least 8 previous generations and 

 probably many more. 



The 2 pure self-coloured Belgians were mated witb 2 albino 

 Angoras, and each albino gave a different result. 



No. 2 albino buck mated wilt No. 1 self-coloured doe pro- 

 duced 26 self-coloured young with no trace of white markings 

 on the extremities. 



No. 3 albino doe mated with No. 4 self-coloured buck pro- 

 duced 16 young, of which one only was self-coloured, all the 

 others being more or less marked with white on the fore-feet,, 

 shoulders, breast, nose, and forehead. 



These white markings, though variable in extent, increased in 

 a definite direction. The slightest markings were either on the 

 tip of a fore-paw or at the end of the nose ; as the markings 

 increased they invaded the whole fore-feet, legs, shoulders, and 

 breast, while the nose-markings extended towards the forehead; 

 in other words, the whole tendency of the markings was towards 

 the Dutch markings, so well known to fanciers. No. 7 was 

 self-coloured, while No. 10 had white fore-feet, legs, righb 

 shoulder, and breast, being the most marked of all ; the others 

 might be said to consist of a series between Nos. 7 and 10. 



As different results were obtained from the 2 albinos, it is 

 necessary to consider the offspring of the 2 lines of descent 

 separately, viz. : — The self-coloured line raised from the No. 2 

 albino, and the marked' line raised from the No. 3 albino. 



(a) The Self-coloured Lme. 



In the first generation all the offspring were self-coloured. 

 In the second generation 3 of the selfs of the first generation 

 bred together and with a pure self produced 37 young, of which 

 35 were selfs and 2 were slightly marked with white, having a 

 few white hairs on the tip of the right paw. The matings were 

 as follows : —
