A HINNY WITH TWIN COLTS 
The large animal here shown is said to be the offspring of a half-blood Percheron stallion and 
a black Spanish jennet, and her twin foals (one of which lived only a few days) are supposed 
to have been sired by a gray mammoth jack. The colts would therefore be three-fourths 
ass and one-fourth horse. (Fig. 5.) 
collect some evidence on the matter, in 
the shape of statements and photo- 
graphs. 
One case first appeared in the No- 
vember issue of the American Journal 
of Veterinary Medicine, Chicago, and 
again in American Farming for Feb- 
ruary, 1916. The facts presented below 
were furnished me by the owner and the 
veterinarian who attended the case. 
J..M. Bryant, of Quincy, Ind., about 
nine years ago bred a dark chestnut 
“half blood” Percheron stallion to a 
black Spanish jennet. The hinny thus 
produced is now 8 years old, 14% hands 
high and weighs 900 pounds. Her 
whole aspect is very ass-like, especially 
her hind parts, but Mr. Bryant says 
her head has more the appearance of 
her sire—her ears being dark chestnut 
color, the same as the stallion. The 
tail shows a good brush or switch while 
the ass has a “‘rat tail.”” She has never 
brayed like a jennet. Some have 
doubted her breeding until they heard 
her voice, which resembles more the 
neigh of a horse. Twice before the 
present case this female produced foals, 
but in both cases the birth was abnormal 
and the colts died. Dr. L. A. Ray, the 
veterinarian who attended the birth in 
question, says of these earlier foals, 
“They were much deformed and were 
unable to swallow, and one had a double 
head from the eyes down.”’ 
This “hinny’” was bred to a gray 
mammoth jack on July 7, 1914, and on 
July 11, 1915, ‘produced the pair of 
twins shown in the cut (Fig. 5). 
The twins were both females. One 
was 25 inches high, black with white 
points, and lived only 7 days. The 
other was 30 inches high and gray in 
color. Dr. Ray on February 17, 1916,
