The pathology and surgical treatment of tumors . coughharassing in character, and difficult breathing alternating with tempo-rary attacks of dyspnea, are some of the leading clinical features. Notinfrequently, papilloma of the larynx undergoes transformation into car-cinoma, as was probably the case in the instance referred to in the sec-tion treating of the Transformation of Benign into Malignant Tumors. Digestive Tract.—The mucous membrane of the cavity of the mouthis derived from the epiblast and is frequently the seat of favorite localities are the mucous membrane of the cheek, theprolabium of the lip, the tongue, the soft palate, and the pharynx. Thenaso-pharyngeal space is frequently studded with papillomatous vegeta-tions. The stomach is almost exempt from this affection. The fre-quency with which the mucous membrane of the intestinal canal isaffected increases in a downward direction. Papillomata are rare in theintestines, while in the rectum they are frequent, and are either PAPILLOMA AND ONYCHOMA. 145.

The writer has repeatedly seen the mucous membrane of thelower part of the rectum studded with papillary tumors varying in sizefrom a hempseed to a cherry (). The symptoms which attend thisaffection of the rectum are hemor-rhage, usually slight, tenesmus, anda glairy discharge. Urhiary Organs.—The urinarytract is very often the seat of papil-loma, and no part of it is are frequently located inthe urethra, and especially around themargin of the meatus in the this locality they are often multi-ple, and they are a source of greatdistress to the patient.
