liberally applied, and maintained thereafter on soft pledgets of 

 surgical cotton, will often have the best results. All foreign 

 bodies must be carefully removed, lacerated flaps and shreds may 

 require suturing, dead portions excision, and finally abscesses or 

 excessive exudate may require the lance, but cooling, antiseptic 

 lotions and an elevated position of the head, are among the most 

 prominent resorts. 



RETRO-BULBAR ABSCESS. 



Schindelka has observed this in the horse, in connection with 

 petechial fever. If connected with meningeal abscess it will be 

 necessarily fatal. In favorable cases evacuate the pus as soon as 

 detected and dress with pledgets of cotton saturated with a mer- 

 curic chloride solution (i : 2000) or other antiseptic. 



PERIOSTITIS OF THE ORBIT. 



This may be shown by the firm swelling of the bone and, in 

 case a wound has been formed, by the contact of the probe with 

 the denuded, hard, rough bone. When thus exposed or necrosed 

 on the surface, or when an exostosis has formed, the bone may 

 be laid open and scraped down to the healthy tissue, and then 

 dressed with antiseptic pledgets. 



TUMORS OF THE ORBIT. 



These may be of different kinds, as sarcoma, encephaloid, 

 osteoma and actinomycosis. They demand thorough surgical 

 treatment, except perhaps in the case of the latter, which may re- 

 cover under iodide of potassium. Emmerich records an extensive 

 sarcoma of the orbit in a cow, weighing six pounds and extend- 

 ing into the nasal sinuses, and chambers, and implicating the 

 cerebral meninges. Moller records cases of .sarcoma and car-
