 cosa, clouded or vascular cornea, one or both eyes invaded, one or more 

 worms in aqueous of each. Connection with filaria of peritoneum and 

 paresis. Treatment: Incision near margin and parallel to cornea under

 vina : F. Cervina : In France, Belgium and Italy ; in damp localities, at all

 Subpalpebral, in lachrymal ducts or sac. Epiphora, congestion, photopho- 

 bia, tenderness, opacity and erosion of cornea. Diagnosis by finding the 

 worms. Treatment : Pick out worms with forceps, wash out with syringe,

Sporozoa. Coccidia were found by Krause in the ocular 

 muscles of the ox, dog and cat. 



Diptera. Different flies are attracted to the eyes of animals, 

 the muscse to suck the tears while the tabanus and simulium dash 

 into the eye attracted by its glitter. The chrysops coecutiens 

 takes its name from its propensity to attack the eye. 



Van Setten, Onderdenham, Holland, extracted through an in- 

 cision in the cornea of a horse, a parasite, which Blanchard and 

 Railliet claim to have been the larva of an oe-strus probably a 

 hypoderma. 



Pediculidae. When lice abound on the surface of the body 

 they are quite liable to attack the palpebrse and often lay their 

 eggs on the eyelashes. The species are those peculiar to the 

 animal attacked and may be either hsematopinus or trichodectes. 

 An ointment of yellow oxide of mercury will usually correct the 

 blepharitis and destroy the fiarasites. 



Acarina. Sarcoptic Acari when colonized on the skin of 

 the head are especially prone to attack the soft skin of the eyelids.
