An Eye Bath, to clear the Eye from extraneous Matters, and 

 to assist the Sight; by Mr. John Duckett Ross, No.

SIR. 



E1NG employed in the jewellery business, I have fre~ EyeliabIe~to 

 quently suffered greatly from extraneous substances getting accidents in 

 i. at- iitl i . certain em- 



into my eyes, at different times, while 1 have been at work; ploy meats. 



and 1 have witnessed many accidents of a similar kind 

 which have happened to enamel-grinders, turners in metal, 

 ; ewellers, lapidaries, and other artificers. These circum- 

 stances led me to attempt some means, which would relieve 

 such misfortunes, and also strengthen my own eyes, which ' 

 were naturally weak. I have now succeeded in inventing 

 an eye bath, possessing all these advantages; which 1 beo- Eye bath, 

 leave to lay before the Society of Arts &c, and hope it will 

 be patronized by them. 



The machine I have 6ent forms an elegant ornament for 

 a lady's or gentleman's dressing-room, and has been found 

 very serviceable in use, of which I will furnish the Society 

 with certificates. 



I remain, Sir, 

 Your most humble and obedient servant,
