FIBROUS TUMOURS. 429 



with blood, especially during exercise or work. The animal 

 makes a snuffling sound in its breathing, and frequently sneezes. 

 The tumour cannot always be seen, but by growth becomes 

 visible to the examiner. Sometimes it grows in the contrary 

 direction, falls into the isthmus faucis, and is apt to become 

 temporarily lodged in the larynx, causing the animal to breathe 

 with the greatest difficulty, with a loud roaring sound, and 

 often to fall down from exhaustion and want of breath. By 

 great effort the animal coughs the obstructing tumour from the 

 larynx into the fauces again, and all at once the roaring sound 

 and difficulty of breathing disappear. Such cases are termed 

 " Bellones " by horse-coupers. 



The only treatment for polypus is removal; and the best 

 method is evulsion by the forceps. The instrument must be 

 passed up alongside of the polypus to its roots, where they 

 must be fixed by strong pressure on the handles ; and then the 

 connections of the tumour must be torn by a compound move- 

 ment of turning and pulling. I have removed them very 

 successfully in this w^ay. The nostril ought to be afterwards 

 frequently syringed with an astringent wash, such as a solution 

 of the tincture of the perchloride of iron. 



When the polypus grows into the fauces, it is quite possible 

 to remove it — if it can be discovered by the hand — by enclosing 

 its pedicle in a noose of strong wire, and tearing it away by 

 strong and continuous traction. If it were possible to apply 

 the " Ecraseur," the removal of this polypus would be rendered 

 a very easy matter. Fibrous tumours, similar to polypi, are 

 found in the ventricles of the brain. 



Fibrous tumours, especially in the horse, are often due to the 

 imprisonment of pus in the deep-seated inter-muscular structures. 

 For example, an apparently fibrous tumour, with well-defined 

 borders, and no appearance of inflamm.ation, is often found in the 

 inferior cervical region, beneath the levator humeri muscle. It 

 arises from the pressure of the collar, and when cut into, 

 will be found to consist of the enormously thickened walls of 

 an old abscess — small in itself, and containing a little pus. 

 Again, these tumours may be found upon those portions of the 

 horse's sides that are liable to be bruised by the shaft of the cart. 

 Indeed, with the exception of the subcutaneous tumours already 

 described, the majority of the so-called fibrous tumours of the
