Description of Mr* Ross's Eye Bath. Plate V, Fig. 3, 

 4, 5, and 6. 



The eye bath ^"'S* *' ^ ilte ^* ls a perspective view of the eye bath, 

 described. which is preserved in the Society's Repository. This ap- 



paratus is supported on a pedestal or tripod. The bath 

 partis represented on a larger scale in section, tig. 5, where 

 a b represents a glass vessel, which has a neck at the lower 

 end, and an aperture at its vertex, as is shown jn the plan, 

 iig. 6, to tit the eye. The neck is cemented into a brass 

 tube c c, which is supported, by being screwed into an orna- 

 mental piece of brass work at the top of the pedestal. This 

 tube encloses a common pewter syringe, the end of which, 

 is cemented into the neck' of the glass vessel, as the section 

 sufficiently explains. The handle e of the syringe has a 

 piece of brass screwed |o it, which slides up and down, be- 

 tween two pieces of brass at A, in the pedestal, and a glass 

 dish i is fixed below the frame, to receive any water which 

 may be spilled by accident. When the instrument is used, 

 the glass vessel is to be partly filled with water, (or any other 

 liquor wjth which the eye is to be syringed,) so as to cover 

 the orifice of the syringe; the patient then places his eye 

 over the aperture in the glass vessel a b, and suddenly lifts 

 up the brass slider at A, to which the handle of the syringe 

 is fixed, so as t« force the liquor contained in the syringe 

 through that in the glass vessel into the eye; the liquor 



, ,. which covers the point of the syringe takes off the force 



Its operation r " . 



cite* ao pain, with which the liquor would be thrown into the eye, so as 



to render the operation not in the least painful.
