II. Actinomycosis. Though much more common in cattle 

 than horses, yet the occasional occurrence of this in the face of 

 the soliped must not pass unnoticed. 



III. Myxoma of Septum Nasi. This is a mucous degenera- 

 tion of the cartilage with destruction and liquefaction of the tissue 

 and the formation of mucous cysts, embracing the whole thick- 

 ness of the septum and standing out in each nasal chamber, of 

 the size of a grain of barley to a hazel-nut. These have been 

 frequently found in the horse, and have been described by I,eiser- 

 ing, Miiller, Bruckmiiller, Siedamgrotzky and Kitt. Myxoma 

 has also been met with in the submucosa of the nose in cattle, 

 a.MdL Jibro-myxoma in the horse. 



Myxo-malacia (Kitt) of the turbinated and facial bones lead- 

 ing to thickening and closure of the walls of the outlet into the 

 nose is a cause of dropsy of the antrum with distension down- 

 ward to obstruct the nasal passage and upward causing bulging, 

 attenuation and absorption of the maxillary, molar, and lachrymal 

 bones. Relief of the tension can be had by perforation of the 

 wall of the sinus through the turbinated or maxillary bone, but 

 the morbid process in the bone remains. 



IV. Sarcoma, Osteosarcoma and Carcinoma. These are 

 found growing from the periosteum, or even starting in the can- 

 cellated tissue and projecting into the nose, where they give rise 

 to symptoms like those of fibrous polypi. Being much softer in 

 texture and more liable to ulceration and degeneration they are 

 likely to cause a much more offensive discharge. There is also 

 more tendency to the implication of the submaxillary lymphatic 

 glands. The only treatment is surgical and recurrence is always 

 to be feared. (See Diseases of the Orbit.) 



We have found them filUng the nasal sinuses, and again ex- 

 tending through the maxillary plates into the roof of the mouth. 



V. Fatty Tumors of the nose are described by Roll, Gurlt, 

 Bruckmiiller, etc., as existing on the septum and in the sinuses. 

 Being simple, they can be removed with great confidence as to 

 non-recurrence. 



VI. Osseous Tumors of the Nasal walls. These are de- 

 scribed by Roll as osteophytes in the maxillary sinus in chronic 

 catarrh, and by Gamgee as osteomata attached to the outer wall 

 of the nasal chamber, which had to be detached by saw and bone 

 forceps. I have found these latter of a soft porous structure easily
