Percivall informs us that the true polypus is at- 

 tached to mucous membranes, and is usually found in 

 the nasal cavities. He tells us that attending the diffi- 

 culty of breathing is a mucous discharge from one or 

 both nostrils, sometimes attended by a discharge of 

 blood. Occasionally, however, pure blood runs con- 

 tinuously from the nose. Inspection in a full light dis-

Treatment. — The services of a veterinary surgeon are, as a 

 matter of course, here needed. The patient must be cast and the 

 head fixed in a position so as to take advantage of the light. The 

 operator then passes into the nostril and around the tumor an in- 

 strument called an ecraiseur, which will remove the tumor without 

 loss of blood. If the instrument is not at hand, the surgeon will 

 pass a ligature around the base of the tumor, and in the course of 

 a couple of days it will be detached. Peecivall recommends 

 -.hat, in bringing down the tumor for operation, we must not use 

 any great force. The pedicle being but a duplicature of the skin,, 

 and Dot a portion of the polypus itself, may be divided anywhere. 

 In some cases, the polypus is so high up within the nostril that, 

 'n order to get at its base, it becomes necessary to make an incis- 

 ion through the wall of the nostril. 



Chabert, in his " Veterinary Instructions," relates the follow- 

 ing : " A horse in a cavalry regiment had been gradually losing 

 flesh, and was quickly and painfully blown at every little exer- 

 tion. Fetid matter began to run from his off nostril, and the 

 gland correspondent enlarged. The horse was supposed by the 

 sergeant-farrier to be glandered, (there being no veterinary sur- 

 geons then in the French service,) and was treated accordingly. 

 After a time, to the confusion and astonishment of the man, a 

 fleshy substance began to appear in the nostril, and which rapidly 

 increased in size. At length a great mass protruded, and the far- 

 1 ior cut it off. No benefit followed ; the nostril was still stopped* 

 the breathing laborious, and the horse daily became thinner and 

 weaker. After the lapse of a twelvemonth, the case attracted 

 the attention of M. Tears, the surgeon of the regiment. He cast 

 the horse and slit up the nostril, when he not only found it com- 

 pletely filled with polypus, and the septum narium bulging into; 

 the other division of the cavity, but, from long-continupd inflam-
