HANDBOOK OF THE TURF, 135 



Indivisible Prize. An indivisible prize is one in 

 which a dead heat is again run for second place, and in which 

 the horses running agree to divide the money or run for an 

 indivisible prize. 



Inflate. The act of inflating the pneumatic tire of a 

 bike sulky previous to a heat, by means of an air-pump. There 

 is of course more or less leakage to these tires, consequent 

 upon their age, use, etc., hence the act of inflating must be per- 

 formed often or less frequently as circumstances require. 



Inherited Qualities. Explained by the quotation : 



Flexibility of ail iciilar iij;anu'iits may be acquired by early training 

 ami retinlar exercise, but. tlie jjroportions of tlie body are inherited. 

 —The Horse in Motion, J. D. B. Stillnian. 



Inspectors. Under the old racing rules, a term applied 

 to those officers of the course now known as patrol judges. 



Intercliang-able Gait. A horse that both paces and 

 trots, is said to have an " interchangeble gait." 



Interfering. An animal is said to interfere when one 

 foot strikes the opposite, as it passes it, in motion. The inner 

 surface of the fetlock joint is the part most liable to this injury, 

 although it may occur to any part of the ankle. It takes place 

 more often in the hind than in the fore legs. It causes a bruise 

 of the skin and underlying tissues, and is generally accompan- 

 ied by an abrasion of the surface, causing lameness, dangerous 

 tripping and thickening of the injured parts. The trouble is 

 chiefly due to deformity or faulty conformation, and when 

 arising from this cause is not easy to overcome. But in many 

 cases it may be prevented by special shoeing. In general, the 

 outside heel and quarter of the foot on the injured leg should 

 be lowered sufficiently to change the relative position of the 

 fetlock joint, by bringing it further away from the center plane 

 of the body, thereby allowing the other foot to pass by without 

 striking. 



Interplialang^eal Articulation. One of the joints 

 of the foot or leg of the horse, situated between any two suc- 

 cessive phalanges of the same leg. 



Intermaxillary Space. A name given to the V- 

 shaped channel, or groove, formed by the spread of the 

 branches of the lower jaw, — which should be sufficiently deep to 

 make its presence quite perceptible. Where this groove is 

 not well defined, but clothed with a thick tissue, the head has 

 a coarse appearance. This space should be broad between the 

 angles of the jaw, in order that the top of the windpipe may 

 have abundant room for its action at whatever position of the 

 head.
