lost in securing this, no matter how well the subject feels, and 

 no attempt should be made to resume work if any irritation is 

 felt. A solution of cocaine is not likely to be at hand, but, if it is, 

 a drop or two will relieve a lot of the immediate pain and facilitate 

 subsequent examination. 



Minute solid particles tend to lodge under the upper lid, so that 

 if the upper licl is seized by the lashes and drawn forwards and 

 downwards over the lower lid the skin surface of the lower lid 

 may serve to wipe away foreign material. If the particle is still 

 felt in the eye after this manoeuvre, the best thing to do is to take 

 the old-fashioned advice and rub the other eye. This evokes a free 

 flow of tears in both eyes, and this flow may sweep a foreign body 

 loosely implanted on the cornea into the lower fornix, from whence 

 it can easily be removed. Rubbing the affected eye is, of course, 

 more like to imbed the foreign body than to release it. 



Should both these methods fail instil oil if much time is likely to 

 elapse before expert medical attention is available, but this should 

 always be secured if a feeling of discomfort persists, whether a 

 foreign body can be seen or not. 



When fragments of broken glass or splinters of metal may have 

 entered or cut the eye, avoid any manipulation other than removal 

 of very gross pieces, as more harm than good is done by unskilled 

 attentions.
