I^or Sits nor Bridles can his Rage rejirain^ 

 And rugged Rocks are interpos'd in vain ; 

 He makes his Way o'er Mountains^ and contemns 

 Unruly Torrents^ and unforded Streams. 



Dryden'j Virg. Georg. Book III. 

 Sutfar above the refly the furious Mare., 

 Sarr'dfrom the Male, is Frantick with Defpair : 

 For when her pouting Vent declares her Pain^ 

 She tears her Harnefs^ and/he rends the Rein : 

 For this when Venus gave them Rage and Pow^r^ ^ 



Their Majiers mangled "Members they devour^ ^ > 



Of Love defrauded in their longing Hour. Ibid. J

Of the "D'tfeafes of the Ejes, 



THere are no Difeafes whereunto Horfes are more liable, 

 than thofe that happen to the Eyes, the Reafon of 

 which will not be very difficult to any who is acquaint- 

 ed with the Oeconomy of a Horfe, but particularly with 

 the Strudure and Mechanifm of the Eye, which is fuch a 

 tender Part, and fo fenfible to the Touch, that the leaft 

 Foreign Matter from without, as a Grain of Sand, or 

 little Dull, will put any Creature into exquifite Pain, and 

 the leaft Determination of Blood and Spirits from within 

 more than ought to come into thofe Parts by the commoi 

 Courfeof Circulation, will have the fame EfFecft. Bu 

 when we conlider the natural Adivity of a Horfe, am 

 that the common Service required of him expofes him mon 

 to Heats and Colds, and to all Manner of Fatigue an< 

 Toil, than any other Creature ; and that of Confequenc 

 he is render'd more liable to Sicknefs, and fuch as is of th 

 worft Kind, he muft therefore be more fubjeft to Infirmitii 

 of the Eyes, and fuch as without a great deal of Care wi 

 be apt to end in abfolute Blindnefs. 



.. 7)Y /. r Now all the Difeafes of the Eyes proced 

 the Eves proceed ^'^^^^^ ^^^^ external Caufes, fuch asWoundi 

 either from ex- Bf^^'fes, Duft, or Other foreign matter gettir 

 ternalor inter- with'n the Eyelids ; or from internal Caufc 

 nal Cau/esy or fuch as are the Effect of Sicknefs, or any Ifl' 

 from anill Con- dlfpofition of the Blood. And laftly, 

 formation of Horfe may be render*d obnoxious to Difeaf© 

 the Eyes^ jj
