But for tllis thebipeds in the walk. it i i i x ^ l)ody would have no support (From an instantaneous photograph.) ^ . during the interval between thesuccessive movements. The consequence of this fact is that the dura-tion of the contact of the foot with the ground is always longer thanthat of its elevation, contrary to the opinions of Vincent and Goiifon,. GENERALITIES OF THE GAITS. All Colin, and Raabe and his disciples, who admit the absolute equalityof the two phases of contact and of elevation. These two periods of the walk, well explained l)y M. Lenoble duTeil/ have been called by him jjeriods of exchange of the contact. Inthe middle of each of them there evidently exists a moment duringwhich the body is equally supported })y the two members at the sametime. This author has also had reason to make three groups of thepreceding six periods of the complete step : two of advancement, twoof complete contact, and two of change of contact. It is easy to understand that the change of the contact with thesoil, in the walk, for example, is all the longer and easier to ascertainas the ffait is slower. As soon as the latter is accelerated so as to sim-ulate leaping, it is then seen to diminish correspondingly. Finally,it disappears immediately as soon as leaping is manifested.
