In this exhibit the name of the most prominent horse in 

 the generation has been selected for designating the several 

 generations. Since the time of the advent of the bicycle 

 wheel, the surging advances of speed which characterize a 

 generation, have continued, as they were before, but the 

 horse has not fallen behind the predicted speed. In time the 

 sudden advance due to this radical improvement in the sulky, 

 will probably be taken up again, and the horse will gradually 

 come back into line with what was shown in the earlier gen- 

 erations. I do not think there is any evidence that the final 

 speed of the horse will differ materially from what was 

 predicted twenty years ago. 



It may be said in closing that when the earlier paper was 

 published, in 1883, there were many who scouted the idea 

 that the trotting horse would ever trot a mile in 98 seconds. 

 It has happened that some of these same persons have now 

 thought it proper to poke fun at the writer because the horse
