the herbivora, but e.speciall}' cattle and sheep, are liable to a dif- 

 fuse anthrax of the eyelid with a special petechial or brownish 

 condition of the palpebral conjunctiva. Malignant oedema and 

 other local bacteridian affections affect the loose textures of the 

 eyelid in a similar manner, but with extrication of gas and crack- 

 ling under pressure. Such cases are complicated by local in- 

 flammation. When in the ab.sence of inflammation the lids pit 

 on pressure, one should seek for some disease of the heart, kid- 

 ney or liver, also for indications of similar dropsical effusions in 

 other parts of the body. Distomatosis and, to a less extent, pul- 

 monary and duodenal strongylosis are especially common factors 

 in sheep. In distomatosis (liver rot) a simultaneous dropsy is 

 often present in the intermaxillary space, the chest or the ab- 

 domen. The puffiness of the eye is especially marked in the pal- 

 pebral conjunctiva, and is exposed by everting the eyelid over 

 the tip of the finger. In trichinosis in man and less frequently 

 in swine, dropsy of the eyelid is often present at the end of 

 the first week. Other swellings of the lids partaking more of the 

 nature of inflammation, result from the stings of wasps, hornets 

 and other insects, from urticaria (in horses especially) and from 

 petechial fever in solipeds. 



In treating such cases the general disorder, if present, must be 

 first attended to, then the removal of any local irritant, and finally 

 the antagonizing of any local inflammation or infection. Astrin- 

 gent and antiseptic lotions are especially called for. 



EMPHYSEMA OF THE EYEEIDS. 



This has been already referred to as occurring in malignant 

 oedema, black quarter and other gas producing infections. It 

 ma}' also come from lacerations made in punctinnng the lachrymal 

 sac, and from fracture of the margin of the orbit — -the air enter- 

 ing the connective tissue in this case from the cavities of the 

 nasal sinuses. The lid feels puffy and crackles when pressed and 

 apart from a general infection it requires only soothing and anti- 

 septic dressings.
