which, by well probing daily, and injections of a solution of

TUMOR UPON THE FACE. 



Those who are much among young horses will have occa- 

 sionally observed osseous swellings arising upon the side of 

 the face, midway between the eye and angle of the mouth. 

 They grow from the superior maxillary bones, have a rounded 

 form, and are broadish at their bases, with hardly any per- 

 ceptible heat of surface, and very little tenderness on pressure. 

 Sometimes one appears; oftener, I believe, there exist a 

 pair. What their origin may be, I know not, unless they be 

 the effects of blows. In composition they are evidently 

 osseous, or osseo-cartilaginous : in fact, they are veritable 

 exostoses. They are nowise hurtful or injurious; but they 

 extremely disfigure the countenance of the animal: they give 

 him a sour, ill-tempered look, and on this account are often 

 sought to be got rid of. 



A three-year old horse came to my regiment, out of the 

 dealer^s hands, with a tumour of this description upon the 

 off side of his face. Not liking the appearance of it, the 

 colonel was desirous I should get rid of it. I blistered it 

 repeatedly. I next tried the effects of an iodine ointment 

 upon it : all to very little purpose however. It was thought 

 to have diminished ; but this, in truth, was very little. I 

 had a notion that stripping it of its periosteal covering, and 

 leaving it bare, might cause it to exfoliate away : but this 

 seemed to be attended with some danger of sloughing 

 open the maxillary sinus ; and therefore the project was 

 abandoned. 



Mr. Charles Percivall, V.S. Royal Artillery, has sent me 

 the following account of the same disease : — 



A four-year-old gelding came into the Horse Infirmary 

 at Woolwich, with a tumour upon the maxillary bone of the 

 off side, followed, some days after, by enlargement of the 

 submaxillary glands, and discharge from the nose on the same
