Eye. When it is very fmall, and {hows itfelf only in the 

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

 if more towards the Surface, a Zpeck ; 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 Blindnef'', which is as 

 common and ufual among Horfes as any other, and that 

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

 ward Coat and Humours appear tranfparenr, and without 

 Blemifli, and this Sort is as difficult to be reaioved as any; 

 becaufe the Fault lies in the Comprefhon of the Retina, or 

 Optick Nerve, by an over-great Diftention of the Vell'els 

 that are interwoven in it. 



When the Eye is onlycover'd with a Film ^^ Cure of 

 or membranous Subllance, unlefs that has «xternalBlind- 

 its Origin from a Scar made on the clear ^''■f^' 

 tranfparent Part of the Cortiea, 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- 

 bright, 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 mirabiiis, as direded in the 2 ijl 

 Chapter ; or the following Eye-JVater, which I have otter* 

 experienced to be moft effei5lual, 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 

 an apparent Defefi: 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- 

 *' folve in it one Ounce of crude Sal Annoniack, letting it 

 ** Hand in that Vellel 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 (hall be 

 '' Occafion." 



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

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

 and therefore may at any Time be made in a larger 

 Quantitv.
