SUPPOSED REPRESENTATIVE OF THE BULL-DOG CATTLE 
This cow is believed to be a hybrid, although judging from descriptions it cannot be a full-

Charles Darwin.

Knowledge of the fata breed has 
been little increased since Darwin’s 
time and, so far as the writer is aware, 
no photographs of it have been pub- 
lished. The JOURNAL OF HEREDITY 
therefore undertook, nearly three years 
ago, to find what had become of this 
curious bovine race, and to secure 
illustrations of it. A fruitless corre- 
spondence was conducted with numer- 
ous South Americans, but finally a 
member of this association, B. Lorenzo 
Hill, of Montevideo, interested himself 
in the case, and for the past year has 
prosecuted a diligent search for informa- 
tion about the breed. The principal 
newspapers of Uruguay cooperated by 
printing the American Genetic Associa- 
tion’s appeal, at the instance of Mr. Hill, 
and another member of the association,

He was finally able to secure the accom-

the district of Chubut. They were at 
once published in several of the most 
widely circulated newspapers of Monte- 
video, accompanied by another appeal 
from the Uruguayan Department of 
Agriculture, in which ranchers were 
asked to assist the American Genetic 
Association in getting more detailed 
information. But in view of the evident 
rarity of Nata cattle at the present day, 
it seems advisable to publish these 
photographs in the JOURNAL OF HERED- 
Iry without further delay. 
A comparison of the accompanying 
photographs, with Darwin’s description, 
makes it seem probable that the animals 
pictured are not full-blood fatas, but a
