This is a diseased growth in the nose, of which there are four varieties.

The common gelatinus polypus is a tumour of the consistence of jelly, pear-shaped, yellowish, slightly streaked with blood-vessels, attached by a narrow neck to the mucous membrane, and apparently consisting of organised lymph. The patient has a constant feeling of stuffing and cold in the head, which is increased in damp weather. If he forces his breath strongly through the affected nostril, while he closes the other, the polypus may be brought into view. There are very often more than one of these tumours. If the polypus be permitted to remain, it continually increases in size, blocks up the nostril, obstructs the other nostril, causes prodigious deformity of the cheek, prevents the passage of the tears, and may even cause death by pressure on the brain.

The hydatid Polypus is a rare species, consisting of a number of thin vesicles filled with a watery fluid, and attached by a stalk.

The carcinomatous Polypus is nothing more than a scirrhous-tumour in the nose. It may be known by its occurring to elderly persons, by the cancerous habit of body, the hardness of the tumour, and lancinating pain.

The fungoid Polypus is a soft red tumour, growing with great rapidity, frequently bleeding, and pursuing the ordinary course of fungus haematodes.

The two last descriptions of Polypus belong to that class of tumours called malignant, and must be treated accordingly. The-treatment of nasal Polypus by removal, either by the forceps or by ligature, is not considered satisfactory, the growth returning again rapidly, and again requiring removal. Mr. Bryant of Guy's Hospital, finds that Tannin used as snuff, whilst it has no effect on the healthy membrane, causes the withering up and disappearance of the Polypus. It should be blown daily up the nostrils with a quill. The removal of the Polypus before the Tannin is commenced is not even necessary. And the best point in the treatment is that the Polypus does not return.
