ON ZHBRA-HORSE HYBRIDS. 59 
hasty retreat. Biddy was the first fairly large animal he ventured 
to approach. One day I tied her up in a court about forty feet 
square, a cloth having been previously bound over her eyes. 
The Zebra in course of time ventured within a few yards; later 
he laid his head across her quarters, and then, for quite a long 
time, across her withers. He next licked her lips, and ended by 
gently nibbling at her ears. Lividently at length satisfied a big 
Horse was after all not so terrible an object, he retired to his 
box and finished his corn. Having once learned the peculiarities 
of a mare he never forgets them. Some of the mares he dislikes, 
while he is very fond of others, getting quite excited when they 
pass his own particular quarters. Donkeys, however, he com- 
pletely refuses to take the smallest notice of. 
Remus—born on the 18th of May, 1896--was, at birth, 
relatively smaller and far less active than Romulus; the period 
of gestation was three hundred and forty-six days. When a day 
old he measured 354 in., his girth being 28 in. On the 18th of 
June he had increased to 384 in., the girth being 36 in. When 
six months old he measured 44% in., the girth being 473 in., the 
circumference at the knee 9$ in., and below the knee 53 in. 
Romulus at six months was 42 in. 
From the first Remus has been extremely friendly, and yet 
in some respects he is more Zebra-like than Romulus. For 
some days he was little more than a machine,—an automaton 
capable of following a moving object and of sucking. All the 
special sense organs were apparently at work, but the brain 
seemed incapable of making much use of the information col- 
lected. If I moved away he followed me, and sucked at my 
fingers or anything else offered him. He heard his dam when 
she called, but he was unable to discover whence the sound came, 
and when he saw her at a few yards distance he failed to recognize 
her. He seemed to like aloes and water quite as much as sugar 
and milk, and did not mind either strong smelling-salts or 
freshly-made mustard. ‘Though he kicked aimlessly when 
pinched, he paid no heed to the application of either warm or 
very cold substances to his skin. When a dog was first intro- 
duced to Romulus, his excitement was intense. He rushed 
about at a furious rate, striking as opportunity offered with his 
fore-feet, and holding his head high and stepping high, as if
