V. 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 

 detached by the knife, and in other cases dense and requiring, 

 chisel, saw and forceps. In one instance the tumor grew from a 

 dense hypertrophy of the maxillary bone which could not be 

 entirely removed because the molar alveoli were implicated. 



VI. Cysts named by Roll and others as present in the mucosa 

 of the ethmoid cells in solipedes often contain larva of the 

 strongylus armatus. 



VII. Angioma may be but an exaggerated development of the 

 abundant venous plexus and erectile tissue on the surface of the 

 turbinated bones. There appears to be at other times an actual 

 increase of the vascular tissue. As might be expected it has no 

 abrupt margin, but gradually shades off into the healthy tissue. 

 The prominent centre has a bluish red or brownish hue. It ob- 

 structs breathing, is apt to bleed under violent exertions in 

 draught, or in contested races, and readily ulcerates with a bloody 

 discharge. If it subsides and heals, it is followed by a whitish 

 puckering like the so-called cicatrix of glanders.
