over that in Fig. 146, the distance on the other two diagonal feet in- 

 creased by 0.44 ft. (3.06 2.62), showing in all the regulating effect 

 of weight on near hind, as well as a somewhat greater reaching out of 

 both fore in this stride of 17.24 ft. It appears again as if a greater 

 stride would have with it a greater separation of front and hind ex- 

 tremities. The conclusion is in a general way correct, and is sustained 

 by other investigations. The comparisons here of the two strides 

 given 16.18 ft. and 17.24 ft. and their respective average distances 

 between fore and hind 2.94 ft. and 3.26 ft. will present with suffi-

cient clearness the general effect of a change of shoeing; and it will 

 also serve as an illustration of the danger that lies in the lengthening 

 out of the animal's body by the strain that is put on its back and its 

 tendons. It is, therefore, well to bear in mind this distance and its pro- 

 portion to the length of the animal as it appears when at rest ; that is 

 to say, such a distance between the extremities when the subject is at 

 rest will, with some horses, decrease somewhat under great speed be- 

 cause of the backward propelling power of the fore legs and the 

 anxiety of the hind legs to gain ground and, so to speak, take a hold 

 of it to effect propulsion. The same observation can often be made in
