PACES OF THE IIOESE. 147 



price. Each one luis suffered himself to be guided in this 

 respect by theoretical considerations. Those who admit equal 

 intervals between the four footfalls, have thought that they 

 found in this type more clearness and a more decided dis- 

 tinction between tlte amble and the trot. The other writers 

 have attempted the realisation of a certain ideal in the kind 

 of pace which served them as a type. For Ka.ibe, it was the 

 maximum of stability, which, according- to his theory, ia 

 obtained when the weight of the body rests longer on the two 

 diagonal feet than on the two lateral feet ; whence arises the 

 choice of the type represented by the notation No. 6. Lecoq, 

 thinking, on the contrary, that the most rapid pace is the best, 

 lias chosen as his type the pace in which the body rests longer on 

 the two lateral feet than on the diagonal ones (notation No. 4). 

 Whatever may be the value of these considerations, of 

 which practical men alone can judge, it seems to us that the 

 physiologist must first of all endeavour to search for facts, and 

 must take simply such types as experiment may reveal to him. 

 It is for this purpose that the investigations have been made with 

 registering apparatus, the result of which will now be given. 



APPARATUS INTENDED FOE. THE STUDY OF THE MODES 

 OF LOCOMOTION OF THE HORSE. 



For the experimental shoe employed in the experiments made 

 on man has been substituted, on the horse, a ball of india- 

 rubber filled with horsehair, and attached to the horse's hoof 

 by a contrivance Avhich adapts it to the shoe.
