Chap. XXI. Of a Wound on the Ejey &:c. 6^ 



in his Eyes, from an ill Conformation of the Eye itfelfj as 

 for Inftance, when the Eye happens to be tou large or too 

 fmall, or when the Pupil, or clear tranfparent Part of the 

 Eye is narrow, and fomewhat longifh, as is obfervable in 

 many Horfes; for in this Cafe the Cryftalline Humour 

 feems to be over-much comprefs'd by the circumambient 

 Parts ; and if any Rheum, or flux of Humours, happen to 

 fall into an Eye that has this Defed in it, the Infirmity 

 will readily Increafe, and in time the Retina^ or Bottom of 

 the Eye, will be quite hid, fo as to produce Blindnefs. Yet 

 notwithllanding all thefe Imperfedions, a Horfe's Eyes 

 may be very good) if he be otherwife of a hearty Difpoii^ 

 tion ; and they may continue good during his Life, if 

 there be proper Care taken of him, and that he meets with 

 no Accident; however, as all Di/eafes are the worfe the 

 more they are complicated, therefore when any Accident 

 happens to the Eyes, its Cure w^ill be the more difficult, 

 where there is, befides the Difeafe, a natural Defedl and 

 Imperfedion in the Eye itfelf. 



Having thus diftinguifh'd between thofe Difeafes of the 

 Eyes that proceed from external Accidents, and thofe that 

 arife from internal Caufes, or from an ill Conformation of 

 the Eye itfelf, or when there is a Complication of thofe 

 Caufes ; we are in hopes, by this general Divifion, the Dif- 

 eafes incident to the Eyes of Horfes will be much the bet- 

 ter underftood, becaufe all the different Sorts of Blindnefs, 

 and all other Accidents whatfoever happening to the Eyes, 

 are reducible to one or other of thefe general Caufes, which 

 not being fufficiently attended unto by Farriers, has made 

 thofe Cures hitherto very imperfe<5l.
