and elsewhere the parents of at least 4000 others, in no case have we the cross 
W. X W. This is undoubtedly an important cross and we endeavoured to obtain 
data on this point by seeking out the pedigrees of all the white dogs whose names 
were known to us. The paucity of material is due to the fact that very rarely 
one of a litter is pure white, and we have no evidence of any attempt tu breed 
persistently from W. x W. * Upwards of 50 pedigrees of ' white ' dogs going back 
to their 16 great-great-grandparents, and in some cases their great-great-great- 
grandparents were drawn up with the colours added in all cases where we could 
ascertain them. But not very definite information could be extracted from these 
pedigrees. There were six cases only of a W. dog with one parent W., three 
white dams and three white sires. Of these six cases of W. from parent W. we 
had no case of the parents of the W. parent being recorded as white. Indeed, no 
case of a W". grandparent at all. One or other of the grandparents was usually 
particoloured white. There were 16 cases in which a white dog was recorded 
from parents hotli of whom were white particolour. In all these cases there 
was white particolour in the grandparents in one or more cases, but quite 
frequently neither parent of a particoloured parent had any white ; for example, 
R. X Bd. frequently gave white particolour. In only one recorded case was there 
a W. grandparent in this series. Where the grandparents of the W. dog through 
a particoloured white parent were R. x Bd. we found the white particolour 
reappeared in the parents of one or other or both of the R. and Bd. grandparents. 
There were 16 cases of one particolour white parent to the W. dog. In all 
these cases except one, there was more or less particolour white in the grand- 
parents. In this one case we have ; 
R. X R. Bk. X Bk. 
R. X Bk.' W. 
[ J 
W. 
But at least three of the great-grandparents, partly on the red and partly on the 
black side, were white particolour. There were 19 cases of white dogs with no 
white recorded at all in their parents, but here again the particoloured white 
appeared almost always in the grandparents. Of the two exceptions the pedigrees 
are ; 
Bk. xBk. Bk. xBk. Bk.xBd. Bd.xF. 
Bk. X Bd. F. X R.'f. 
W. W. 
But in both cases the particolour white occurs in the great-grandparents. 
Of the 18 W. dogs with no recorded white in the parentage, four were from 
Bk. X R. crosses, one from a Bk. x Bk. cross, and six from Bd. x Bk. crosses. 
* Mr W. F. Lamonby informs us that no breeder has made a speciality of a pure wliite strain ; and 
considers that the attempt to create it would fail as the colours of former generations would crop up. 
This shows at any rate that leading breeders' opinion does not believe in white breeding true.
