TUMOURS. 83 



I published some notes on a case,* which I think may not be 

 unworthy a place here. I said : 



" M. Lafosse,f professor of clinical medicine in the veteri- 

 nary school of Toulouse, had under his treatment a four- 

 year-old mare, which, two months before admission into the 

 infirmary, was affected with a phlegmonous tumour in the 

 vicinity of the left ear. This was opened; the wound that 

 resulted rapidly contracted, but a fistula remained. On the 

 8th of February, 1855, when Lafosse first saw the case, he 

 found a painful tumour, with a granulating wound just behind 

 the scutiform cartilage, and near the upper part of the parotid 

 gland. The mare was restless, and the parts could only be 

 examined in a complete manner the day after, when she was 

 cast. By probing, he ascertained that at the bottom of the 

 fistulous tract was some hard substance, which he supposed 

 to be the scutiform cartilage in An ossified state, or a portion 

 of the temporal bone exfoliating. A severe operation was 

 performed, and the solid object, with some difficulty, extracted. 

 It was double, deeply seated, and firmly adherent to surround- 

 ing textures. Slight haemorrhage occurred, from division of 

 the anterior auricular artery, which was easily stopped; the 

 wound was dressed, and the animal soon recovered, having 

 shown only a few symptoms of sore throat after the operation. 



" I shall not translate M. Lafosse's description of the pro- 

 ducts he extracted. They were composed of tooth-substance ; 

 and although it has been questioned whether it is real tooth 

 that is developed in the shape of accidental growths in the 

 vicinity of the ear, still it is now a well-established fact, how- 

 ever puzzling to the minds of some it may be to comprehend 

 the origin of their existence.
