In the illustrations the sequences of phases are arranged 
in the direction of the movement, or are marked by an 
arrow. 
When the consecutive phases of a movement have 
been synchronously photographed from two or more points 
of view, the fore-shortened phases are arranged in the 
ANAL YSES.

same direction as the laterals; the corresponding phases of 
any series—if the small size of some of their numbers 
prevent their being readily seen—can be ascertained by 
counting the succession. 
The time-intervals between the phases are marked in 
thousandths of a second; the time of a complete stride, 
approximately, in hundredths of a second. 
The distance measurements are, approximately, given 
in inches, and in metres roughly calculated on the basis 
of forty inches to a metre. 
In the analyses of the gaits the word “spring” must 
not always be taken to imply a leap ; it is frequently used 
as a convenient term to indicate the last impulse of a foot 
prior to its being lifted from the ground. 
During very rapid motion by a good horse, the aggre¬ 
gate of the body preserves a nearly horizontal line, the 
period of transit without support being usually too brief 
for the attraction of gravitation to have much effect, and 
the body of the animal is nearer to the ground by the 
height of the fetlock or pastern-joint than when standing 
at rest.
