When two horses run a dead heat for first place, all prizes to which first and second horses would have been entitled shall be divided equally between them; and this applies in dividing prizes whatever the number of horses running a dead heat and whatever places for which the dead heat is run. Each horse shall be deemed a winner and liable to penalty for the amount he shall receive.
