ANNALS OF HORSEMANSHIP. 



LETTER THE THIRD. 



From a Half-nvay Houfe bettueen Cambridge and Newmarket, 



March 26, 1789. 

 SIR, 



HAVING long been earnellly engaged 

 in the ftudy of mathematical fcience, and 

 being fond of riding, two purfuits ufually 

 thought incompatible, I have been enabled, 

 by means of this lingular union, to ftrike 

 oiit fome important difcoveries in both 

 branches. The mathematical improvements 

 in riding v^ill, I hope, deferve a place in 

 the Annals of Horfemanfhip : my equeflrian 

 difcoveries in mathematics you mufl permit 

 me to.referve for the Ladies Diary, 



My love for equeftrian agitation is, I be- 

 lieve, more general than that of any other 

 perfon ; for whatever fatisfadtion may be 



C ufually
