„C'est pourquoi les descendants des chien-loups restent des chien- 
loups, c'est aussi pourquoi tous les Malamutes, qui conséquemment ne 
sont que des chien-loups ont le caractère bon, à exception très rare, et 
non le caractère méchant du loup.” 
„A exception très rare”; this gave me my opportunity, so I asked 
Fr whether he knew of any other exceptions. 
With the greatest frankness this champion of the constancy he 
thesis of wolf-dog hybrids told me that reversions were common, that 
he had even seen in a single litter : dogs resembling a New Foundlander, 
a St. Bernard, a Shepherd, a „Grand Danois”’, an Aïrdale and a Samo- 
jede. He also had seen descendants quite close to „le loup gris”, „le loup 
noir’ and „le loup brun’’, so that there is very little doubt that dog- 
wolf hybrids segregate. 
The fact which struck me at once, after but a cursory glance at these 
dogs, was the occurrence of eyes of different color in the same indivi- 
dual among them. Such animals had a brown and a grey eye, a condi- 
tion seen COTE but very rarely, among men, horses and dogs. 
The „grey” eye evidently lacks the yellow or brown pigment of the 
wolfs-eye or that of ,normal’’ dogs, but is not entirely without pig- 
ment, as the eyes are grey and not red. 
Among some 30 Malamute dogs present, I saw, on cursory examina- 
tion only: 
1 animal with both eyes grey 
4. ,, with one eye grey and the other brown 
2, with one eye brown, and the other exactly 
half brown, half grey 
2 ,, with both eyes brown, but one of them 
with a grey sector 

These wolf-dog hybrids would evidently furnish admirable material 
for the study of this peculiar anomaly ; it is to call the attention of Cali- 
fornian geneticists to this opportunity, that this short note is published.
