io8 Of the Difeafes of the EYES. 



defcribe thefe internal diforders with their 

 fymptoms. 



The fym- 'Bhefe generally make their appearance, 



ptom^of vvi^en a horfe is turned five, coming fix ; 



ancrca?a-^ at which time one eye becomes clouded, 



rads. the eyelids being fwelled, and very often 



fhut up ; and a thin water generally runs 



from the difeafed eye down the cheek, fo 



fliarp as fometimes to excoriate the fkin ; 



the veins of the temple, under the eye, 



and along the nofe, are turgid and full : 



though iometimes it happens that the eye 



runs but little. 



This diforder comes and goes till the 

 cataract is ripe ; then all pain and running 

 difappear, and the horfe becomes totally 

 blind, which is generally in about two 

 years. During this time feme horfes have 

 more frequent returns than others ; which 

 continue in fome a week or more, in others 

 three or four; returning once in two or 

 three months, and they are feldom fo long 

 as five without a relapfe. 



Adryca- There is another kind of moon blind- 



laraaje- fjefs, which is alio the forerunner of ca- 



taradls, where no humour or weeping 



attends. The eye is never fhut up or 



clofed here, but will now and then look 



thick
