Experiments and their Verification 



fore have a bar only across toe (also tilted to left) and the quarters 

 near the heels swelled in the web of the shoe so as to form the same 

 contact with ground as with the double bars. The hind shoes are set a 

 little differently, the near being full, and the off flush at the toe. A 

 week before that the subject was tried with the same shoes, but without 

 toe-weights. The extensions and separations of fore and hind are given 

 in Fig. 107. Always allowing for the increase of separation due to the 

 increase of stride and speed of the second trial, there is here a greater

separation of fore and hind by 0.4 feet or 4.8 inches (4.26 3.86) a 

 part of which, at least, seems to be due to the toe-weights. 



Taking this same case and replacing a 3 oz. toe-weight on off or 

 right fore for the 2 oz., there appears a different extension, as given in 

 Fig. 108; namely, the left fore increases its extension to about 1.56 

 inches and the left hind leg now shows an increased extension over 

 that of the right hind leg by 1.8 inches. This sudden reversal of ex- 

 tension behind, from right to left hind, is due to the effect produced 

 by the heavier toe-weight on right fore.
