Whether it would be possible to obtain a higher 
rate of hereditary speed, after horses had been taught 
to practise the rota instead of the cross - gallop, is 
problematical. 
In the rotatory or rota-gallop, a different system of 
foot-fallings prevails ; the consecutive supports revolve, 
as it were, in one or the other direction around the 
body of the animal. This method of galloping is satis¬ 
factorily demonstrated by series 56, two strides of a 
small coursing hound, with a national reputation for 
speed, and, although only about 16 inches high, the 
winner of many trophies from larger animals. 
We will commence the analysis with phase 6, which 
exhibits the hound on A, and about to spring therefrom 
into the air, where we find him in 7, with all the legs 
flexed under the body ; the two fore feet far to the rear 
of •, on which he presently alights, and quickly follows 
with O, from which he takes another spring, and in 9 we 
find a phase somewhat resembling the unique modern 
conventionality ol the galloping horse. After a flight with 
outstretched legs, the landing takes place on A. In 
11 the support is transferred to A, and we arrive at a 
virtual repetition of the phase with which we commenced 
in 6. 
In series 57 a powerful, heavily built mastiff is doing 
his best to emulate the speed of the racing hound ; his 
weight, however, is against him, and although he effects 
a spring from a fore-foot, it is beyond his capability to 
spring from a hind-foot. 
Owing to the extreme heat of the day, the manipulation 
MOTION. 
of series 58 leaves much to be desired ; but it is a good 
illustration of the stride of a fallow-deer in captivity, 
followed by its frightened fawn. 
In phase 2 A is on the ground, and is followed by 
A ; had not long confinement in a small park impaired 
the elasticity which the deer would have exhibited in its 
natural state, a phase would have occurred between those 
of 3 and 4, in which all the feet would have been off 
the ground. A is followed by O, and that again by •. 
Between 6 and 7 the animal was entirely free from 
support, which now begins to be furnished by A, with 
a recapitulation of 2. The fawn in the meanwhile was 
soaring aloft, nor did it descend until a considerable 
distance beyond where we leave it in 9. 
The wapiti, or, as it is sometimes called, the elk, has 
the same rotative sequence of limb movements and foot- 
impacts as the dog and the deer; so also has the 
antelope, and it is probable it will be found with the 
moose. 
The diagram reproduces at a glance the sequential 
phases of the rota-gallop ; or, the rotation may be accom¬ 
plished in the reverse direction.
