Eye. When it is very fmall, and fhows itfelf orily in the 

 Bottom of the watry Humour, it is then called a Dragon ; 

 if more towards the Surface, a Speck ; and when it comes 

 to its Maturity, and covers the whole Pupil, or Apple of 

 the Eye, or when it is grown pretty large, it is called a 

 Pearl. But there is one Sort of Blindnefs, which is as 

 common and ufual among Horfes as any other, and thaC 

 is, where there is no vifible Defect in the Eyes, but the out- 

 ward Coat and Humours appear tranfparenr, and without 

 Blemifh, and this Sort is as difficult to be removed as any; 

 becaufe the Fault lies in the Compreflion of the Retina^ or 

 Optick Nerve, by an over-great Diltention of the Vellels 

 that are interwoven in it. 



When the Eye is only covered with a Film T^^^e Cure of 

 .or membranous Subftance, unlefs that has exurnalBlind- 

 its Origin from a Scar made on the clear ^^f^- 

 tranfparent Part of the Cor?iea^ or horny Coat, it may, and 

 is often cured by external Applications only, and fuch as 

 are very eafy and fimple ; as the Juice of Celandine, Eye- 

 jbright, and the like, dropt into the Eye ; but when there 

 is a Scar, or if the Film adheres very clofe to the Subftance 

 of the Eye, Things of a more powerful Operation will then 

 be requir'd, as the camphorated Water, or the Water made 

 by a Solution of the Lapis mirabilis, as directed in the 2 ijl 

 Chapter ; or the following Eye-IVater^ which I have often 

 lexperienced to be moft effedual, not only to clear the Eye 

 from Films, ^r. but do the greateft Service in all Rheums 

 and Defluxions, and even cure thofe where there has been 

 m apparent Defeat on the Cornea. 



" Take unflack'd Lime four Ounces, and pour upon it 

 ■' a Quart of boiling Water; after it has fettled fome 

 ' Time, and grown clear, pour it off gently from the 

 ■' Lime, and then filter it through Brown Paper, and put 

 ' it afterwards into a clean Brafs or Copper Pan, and dif- 

 ' iblve in it one Ounce of crude Sal Ar?noniacky letting it 

 ' ftand in that Veflel until it turns to a very beautiful blue 

 ' Colour, then filter it as before, and keep it for Ufe. 

 ' Let four or five Drops of this Water be inftill'd into the 

 ' Horfe's Eye every Day, once or oftner, as there fhall be 

 ' Occafion." 



This Water will keep a long while, and is not only 

 feful to the Eyes, but to wafh all old obftinate Ulcers ; 

 nd therefore may at any Time be made m a larger 

 > 'antity,
