sist in the continued application of the 1 per cent, carbolic 

 acid solution, or in applying continually a cloth saturated 

 with a solution of 5 to 10 parts of antipyrine and 100 parts 

 of water. After the painful and feverish stage is past a few 

 drops of a solution of 2 parts of potassium iodide and 100 

 parts of water may be used two times per day. If the cornea 

 be perforated the aqueous humor escapes, and this leads, in 

 most cases, to inflammation of the entire eye, resulting in 

 loss of sight and generally in the destruction of the eye- 

 ball. 



Occasionally a perforating wound heals by granula- 

 tion, the iris becomes free and sight is restored. But most 

 frequently in such cases the iris remains attached to the 

 wound or scar tissue of the cornea and prohibits the light 

 from passing into the eye. If the perforation is near the 

 margin of the cornea, a few drops of a solution of 1 gr. of 

 eserine to 1 ounce of water may be applied, two times per 

 day. But if the perforation is near the centre of the cornea 

 a few drops of a solution of atropine 1 gr. to water 1 oz. may 

 be used, night and morning. By the use of eserine the 

 pupil is contracted and the free borders of the iris are taken 

 away from the marginal wound in the cornea. By the use 

 of atripine the pupil is expanded and the borders of the iris 

 are removed from the edges of the central corneal wound. 

 Infectious and general inflammation of the eye may be ob- 

 viated by adjusting over the eye a cotton or linen cloth moist- 

 ened every half hour with a solution of carbolic acid 1 part to 

 water 100 parts; or corrosive sublimate 1 part and water 

 1000 parts!

Inflammation of the cornea may involve the super- 

 fi.cial layer, or the middle layer of the cornea; it may em- 

 brace only part of the cornea or may be diffuse — extend over 

 the entire cornea. The partial or limited form is generally
