l8 ANNALS OF HORSEMANSHIP. 



this method produced a rotatory inftead of 

 a re6liUnear motion. When a horfe has run 

 away, I have, to avoid the wafte of force 

 in my own arms, calculated the neceflary 

 diminution of it in his legs ; but, unfortu- 

 nately, eftimating it as the fquares of the 

 diflances multiplied into the times, I was 

 frequently daflied againll walls, pitched over 

 gates, and plunged into ponds, before I dif- 

 covered that it is not as the fquares of the 

 times, but merely as the times. I mention 

 thefe circumftances by way of caution to other 

 theories ; not being at all difcouraged myfelf 

 by fuch trifling failures, and hoping, by 

 your affiftance, to convince the world that 

 no man can ever become a perfedl rider, un- 

 lefs he has iirfl: made mathematics his hob- 

 by-horfe. You will pardon this innocent play 

 of words on a fubjedt fo ferious, and believe 

 me to be. Sir, with great efteem. 

 Yours, &c.
