CHAI.AZION. 



This is a pea-like tumor growing from the tarsal cartilage, its 

 flattened side toward the mucosa, which is red and angry, and 

 its round surface toward the skin. When manipulated between 

 the fingers it moves with the tarsus. It is usually of slow growth 

 and may continue for years apparently unchanged. Some have 

 thought it tuberculous, but its true nature is uncertain. Warner 

 records the disease in the horse. 



Treatment consists in incision and removal of the tumor, cur- 

 retting of the cavity, and after antiseptic douching, suturing the 

 lips. 



TUBERCUIvOSIS OF THE EYELID. 



Described by Jewsejenke in the lower lid of birds, this is mani- 

 fested by small, hard round knots, covered by bluish red, or yel- 

 lowish red skin, and when incised showing a characteristic miliary 

 tubercle, with bacilli and sometimes' a caseated centre. It is 

 treated by incision, curretting and caustics. 



TURNED-IN EYEIyASH. TRICHIASIS. 



Sometimes an eyelash grows inward so as to impinge upon the 

 front of the eyeball, or even to extend between this and the eye- 

 lid. The condition exists in entropion but trichiasis is rather the 

 deviation of one or two cilia by reason of their false direction, in- 

 dividually. It may occur as the result of a pre-existing inflam- 

 mation affecting the edge of the lid and the follicle, and the 

 offending hair is not only badly directed but small and shrunken 

 as well. On this account it is not always easy to recognize it, 

 and accordingly in cases of conjunctivitis without apparent cause
