ON THE WALKING PACE. 159 



on the point of striking tlie ground, will nut reach the place 

 of the fore-foot on the same side. 



The elevated and lengthened trot is represented in fig. 49, 

 which hns already served to show the rider and his horse 

 furiiisliLd with the ii:s ruments for the purpose of forming 

 tracings of the various paces. The animal is depicted at the 

 instant which, in the notation, is represented by a dot ; that 

 is to say, during the time of suspension, at the moment when 

 the left diagonal biped has just riseu and the right diagonal 

 biped is about to descend. 



OF THE WALKING PACE. 



Experiments on the icalking pace. The explanations into 

 which we have entered in order to analyse the tracings of a 

 trot, will facilitate the interpretation of that of the walking 

 pace, represented in fig. 50. These tracings have been obtained 

 from the same horse as the preceding ones. 



If we let fall a perpendicular from tho points at which the 

 curves commence, we shall have the position of tho successive 

 impacts of the four legs. On account of the thickness of the 

 style employed to trace these curves, the foot corresponding 

 \\ith each of them is easily recognised, therefore we cau 

 maik on each of these perpendicular lines the initial letters 

 of the foot which at this moment reaches the ground. The 

 order of succession of impacts is represented by the letters 

 A I), P G, A G, P D ; that is to say, right fore-foot, left hind- 

 fnot, left fore-foot, r'ujht hind foot, which is the succession 

 admitted by writers on the subject. 



There remaius to be determined the greater or less regu- 

 larity in the succession of these impacts, and the relative 

 extent of the intervals which separate them. For this purpose 

 it is sufficient to construct the notation of the rhythm, of the 

 pressure of each foot according to the registered curves. 

 This notation for fig. 50 shows that the interval which sepa- 

 rates the impacts is always the same, and, consequently, that 

 the horse rests during the same time on the lateral as on the 

 diagonal bipeds. But this is not always the case. 



That we may render the successive positions of the centre 

 of gravity easily understood, we will explain in few words the
